On October 8, the 2016 Charlotte Mini Maker Faire was held at Discovery Place Science. From audience to venue, the event played a number of roles. Local makers who had previously attended the event and others like it saw another opportunity to exhibit the things they were creating. For newcomers, it showcased the things that can be done with technology, art and everyday tools. In addition to these groups, the venue of Discovery Place proved more than adequate shelter from the wind and rain caused by Hurricane Matthew, which meant not only something to do for locals on a rainy day, but a great destination for those who had to evacuate from areas to the south and east and would otherwise be stuck in a hotel.

From ShopBot’s stance as exhibitor, this year’s Charlotte Mini Maker Faire was also different. Not only did they have the help of Eric Schneider, a local maker and Handibot owner from nearby Davidson, NC, but had to improvise the setup since the booth had been moved indoors (ShopBot’s was one of the stations originally planned to be outside on Tryon Street). The new location was Kids U, a multipurpose room that usually houses bugs, snakes and other critters, which were cleared out to spare them from the noise and crowd. The space was shared with Southern Piedmont Woodturners, a nonprofit organization dedicated to spreading the art and education of woodworking.

New technology meets a centuries-old process with Handibot-cut printmaking.
In true maker fashion, the experience was defined by improvisation. With the new location, people would have a hard time locating both groups. Luckily, Discovery Place had a five-foot-long T. Rex they had cut on their in-house ShopBot. The dino was put to work right away to help guide visitors over to the station. Immediately outside the room, Eric set up his printmaking station. He cut a set of letter and character stamps on his Handibot, as well as a series of layered pumpkin prints that, when used in a certain order, created a striking glow-in-the-dark print that anybody could make. The stamps proved not only popular with kids, but made parents and makers wonder how they were cut and drew them into Kids U, where they could see the Handibot in action, cutting names and figures drawn in SmoothSketch with FabMo, ShopBot’s wireless interface software.
Kids and parents who had made prints outside were interested to come in and see how the Handibot worked.
Despite all the last minute planning and changes, the Charlotte Mini Maker Faire was a huge success. Rather than prove a hindrance, the rain and wind actually drove a new audience into Discovery Place Science. Makers from all over the Charlotte area and beyond were able to share all the creative and interactive things they were doing, which provided a day full of welcome distraction from Hurricane Matthew and its effects.
One of my favorite things about attending Maker Faires (large or small) is the moment you witness someone make the connection of how something is made—and then see the leap they make to quickly translating that new information to something they want to make. Maker Faires are ripe with individuals and organizations ready to show and share what they know to empower others to learn, discover, and participate.
The Maker Ed event on Friday, September 30th kicked off the 7th Annual World Maker Faire in NY. The event gathers educators together to grow hands on learning, create makerspaces, collaborate on curriculum, and more. Education spaces, from science centers to libraries, from hospitals to schools, to administrators and educators, are working with students of all ages and abilities to create environments that engage and activate young minds. During Maker Ed, we heard example after example of success stories: kids who were disinterested and checking out of school that undergo a change—they lock in on things like music, electronics, construction—finding their voice, interests, and talents. Events like this are encouraging for the future of education.
ShopBot had two booths this year for the Saturday/Sunday, Oct 1st & 2nd, event and a team of 6 ShopBot staff on hand. One of our booths highlighted the Handibot® Smart Power Tool Adventure Edition and its accessories. Our Smooth Sketch app brought out the artist in kids and adults alike. ShopBot’s Al-Solo Nyonteh and Clarke Barry had visitors draw with a finger on the tablet or phone, press “go,” and the Handibot carved out drawings while they explained what CNC is. It’s a quick way to make the connection between drawing on the computer (CAD) and having the machine cut, carve, mill, or drill your file (CAM).
Brian Owen, our lead engineer on Handibot, demonstrated using a jig that comes with the Handibot, to extend the work area by tiling and showed off the plotter pen attachment – a crowd favorite!
The second ShopBot booth was home to the ShopBot Desktop MAX. You can go from product idea to full production manufacturing with a ShopBot Desktop MAX. Its cutting area of 36”x24” makes it a great fit for everything from guitar making to signs to full size furniture parts. Our very own Bill Young created a couple of jigs to make skateboards, many which were cut throughout the Maker Faire. He showed the whole process from glueing up 1/8” baltic birch, to forming the wavy shapes in custom jigs (created on the ShopBot of course!). Every hour or so, he and Kevin Putvin, our lead engineer who designed the Desktop MAX, cut one of the boards profile on a special jig made to replace the entire table on the MAX. People flocked to see the boards come to life. We had several artists decorate boards before the event that were meant to draw lots of people to our booth—and did!
What an amazing playground for our future leaders, inventors, academics, and creatives. I’m glad ShopBot is a part of this movement and that we can play a role in helping people make their future.

Within 2 hours of receiving his Desktop, David had it up and running.
David Sheffield was born and raised in Buffalo, NY. This city, like many Rust Belt towns, possesses a well-honed sense of pride for its sports teams and historical manufacturing contributions. David’s small manufacturing company, Buffalo Bottle Craft, creates simple products that let others around the country show pride for their sport teams, too.
Buffalo Bottle Craft makes bottle openers concealed in hockey pucks, baseballs and golf balls. Sold with a favorite sports team name or customized logo, David sells them to individuals and also has a thriving wholesale business. His 400 sq. ft. shop is located in The Foundry, started by a few of his friends. David’s manufacturing process utilizes the ShopBot Desktop model along with a Mimaki UV Digital Printer and a few other tools. Having already machined around 40,000 hockey pucks and 2000 golf balls in less than 3 years, David’s mastered machining these alternative materials.
The Puck Opener was David’s first product
The Baseball Opener is still made using a drill press
Trained as a mechanical engineer, David always wanted to start his own business. He gained exposure to many different processes including CNC while working for an engineering company that designs and builds assembly line systems. Making drinking glasses out of wine bottles was a good side business. But since each cup was handmade it wasn’t scalable. David is a huge sports fan, particularly hockey. After seeing a friend make a bottle opener out of round chunk of wood that looked like a hockey puck, he got an idea. Conferring with this friend, who wasn’t interested in making hockey puck bottle openers, he ventured into making them himself.
Initially David used a drill press. But again, the process wasn’t scalable. So began his hunt for an automated system, which brought him to ShopBot Tools. Compared to other CNC machines of similar size, the Desktop met his production needs. “I was looking for something I could pull out of the box and start up,” David reflects. “If you are doing small products like I am, having a full size machine doesn’t make sense.” In anticipation of its arrival, David watched a few video tutorials. And when the machine arrived, “I pulled it out of the crate, put it on the table and had it running within 2 hours,” he remembers. And with it running for 8 hours a day, the machine stands up to the challenge. A local company, Dynamic Saw, creates custom bits for him and his custom jigs help to machine 2000-3000 items for inventory.

This photo speaks for itself.
Buffalo Bottle Craft’s website allows customers to use their own designs to customize his products. David can handle up to 3000 customized items in an order. David found this same customized service in ShopBot’s lifetime tech support. “That is what drove me to the original purchase, and the forum and how helpful everyone was there,” David offers. “Just being able to talk with someone over the phone, Frank or any of those guys, or send them a part file to look at” has been invaluable.
David originally tried patenting his product but found the process costly ($5000 for initial drawings and paperwork from a lawyer) and not necessarily helpful, and decided not to pursue it further. “The terminology the lawyers use is a defensive thing, not an offensive thing. If someone copies your patent, then you have to go after them. It is your money again,” he experienced. As David sees it, “instead of putting resources towards a patent I am trying to be the first to market, the best product offered, and get the most people to see it. My resources are better spent doing it that way than going after a patent.” He does have a trademark on the name, which cost him $2000 to do.
During the past 3 years, David also figured out the marketing side of things. Like many young entrepreneurs, he posted his first product, the hockey puck, on Reddit: It drove sales forward. He’s done this with each subsequent product, only posting 1 or 2 times about them. “Reddit readers don’t like it when you try to sell them something,” David says. His products were featured in various beer publications after he sent them an email and a free sample. David laughs, “I only started doing that actively at the beginning of this year and wish I had done that years earlier. It has really helped generate wholesale traffic.” With 30-35 wholesale accounts at any given time and constant re-orders, David created display cases, too, to hold more multiple items.
Buffalo Bottle Craft has it’s own website, and the products are also sold through Amazon, Ebay, Etsy’s wholesale branch, in stores and brewpubs.
The display cases are made using Baltic Birch plywood.

Teachers and students with their finished projects
When Rick Sheldahl, Career and Technical Education Director of the Durham (NC) Public School System, and Don Ramsey, carpentry instructor at Southern School of Energy and Sustainability visited ShopBot in 2014, they were looking for an affordable CNC machine that could help their students set up a production shop. Rick had budgeted about $25,000 for the PRSalpha with a spindle that would take a full sheet of plywood. ShopBot welcomes visitors and gives tours (with an appointment), but it is primarily a production facility and does not maintain a showroom. So the only full-size gantry tool available to demo was the 4′ x 8′ ShopBot used in the production of ShopBots, which includes the Automatic Tool Changer (ATC) and Vacuum Hold Down system. Don and Rick were smitten. With visions of training students for the work world, creating quality furniture that could be sold and the proceeds going towards scholarships for the students, and summer programs that would not be subject to the “bells” of the regular school year, Rick reworked his budget to purchase the full Production package for Southern High.
Fast forward to the end of the school year, 2016. Rick found himself with an opportunity to purchase CNC equipment for other high schools in the Durham Public School System that would be useful for CTE and STEM education. So, he ordered a number of the smaller ShopBot CNC machines: Desktops (24″ x 18″ cutting area), and a Desktop MAX (24″ x 36″ cutting area) with Rotary Indexer, Buddy (24″ x 32″ cutting area) with a 4′ power stick for the Production Shop. Then, he arranged for training for the teachers who might have found themselves with a piece of equipment that they had not requested, and had no idea of how or why they might want to use it.
Background/experience of teachers and students from the Durham Public Schools (names cropped out to protect the privacy of students).
Training took place at ShopBot Tools on a Saturday in September 2016. Teachers and students from three high schools spent the day at ShopBot, getting hands-on experience with ShopBot Desktops and a Buddy. The background and experience level varied. Two teachers were coming from a very strong woodworking background, but with little experience using Computer-Aided Design (CAD) software. Michelle Joyner-Ricci runs the carpentry program at Jordan High School, and has years of experience with making things using traditional hand tools, power tools and mills. She had requested a milling machine that was adjusted by dialing in the measurements, and instead found a computer-controlled digital fabrication tool in her shop. Prior to the training, she had had a 30-minute introduction to the ShopBot Desktop and VCarve Pro CAD/CAM software at a CTE meeting over the summer. Don Ramsey and his student, a junior, came with a year’s experience using the PRSalpha Production system. They were ready to learn more about how to unlock the capabilities of VCarve Pro CAD/CAM software and the ShopBot.
The other three teachers were experienced in Computer-Aided Design (CAD) software such as Inventor, AutoCAD, and Revit, but had limited experience with how to take those designs and use Computer-Aided Milling/Machining (CAM) software to prepare them for machining on a CNC machine. Adam Davidson and his student from Riverside High School participate in the engineering curriculum, Project Lead the Way, which uses Inventor as its CAD program. The program includes PLTW’s CIM (Computer-Integrated Manufacturing) component to manufacture the objects designed in the 3D-rendering CAD software, but Mr. Davidson did not regularly use the older CNC machine they had at the school. Demetre Harris (Southern) uses Inventor, and James Lee (Southern) had 20+ years of experience using AutoCAD in the real world before singing on to teach AutoCAD at the high school level. Two other students from Southern also attended the class.
Instructors Sallye Coyle and Al Nyonteh introduced themselves and showed examples of the types of machining strategies possible with the ShopBot. Sallye also described the different types of bits used to create each of the strategies.
The ShopBot CNC machining at one depth (2D), engraving (VCarve) and machining in 3D (rounded 3D with pattern behind it)
Three general categories of bits are:
- End Mill Bit: flat on the bottom for machining at one depth (example: cutting through materials or pocketing to one depth)
- V-Bit: 60 or 90 degree for engraving or V-Carving
- Ball Nose Bit: round on the bottom for machining a 3D model
Hands-on experience with using the ShopBot control software to move a ShopBot around in X, Y and Z axes, and writing simple commands to tell the ShopBot where to go went a long way towards removing some of the mystery.
Moving the ShopBot around in the X, Y and Z axes.
Al and the teachers/students watching the ShopBot Desktop in action.
A tour of ShopBot’s facility gave ideas of what kinds of careers are available at a small-scale manufacturing facility: everything from Production to Engineering/Product Design/Electronics, to Customer Support areas such as Technical Support, Sales Marketing and Business Administration. Throughout the building are examples of things that were made with a ShopBot: vacuum tables for holding down parts while machining, prototypes of aluminum parts for new products, signs made of acrylic that include moving parts and lighting with LEDs controlled by Arduino programmable electronics (shields or circuit boards machined on a ShopBot), desks that take advantage of ShopBot’s precision to make living joints (bendable plywood) or press-fit joints, ShopBots making Handibots. Samples machined in 3D with or without the rotary indexer were also a source of inspiration.
Working in pairs, teachers and students went through an exercise that demonstrated the entire process from design idea to finished product. They used the CAD ( what and where) side of VCarve Pro to design a sign, the CAM (how) side to toolpath the design so that it would look engraved, and generated the machine code that the ShopBot would use to move the tool in the correct paths. Included in the design and toolpathing options was an example of how to place hold down screws in the work piece so that the work piece would not move under the spinning router bit, and the spinning bit would not hit a hold down screw.

Each participant then set up a ShopBot to machine their sign. Using a checklist and printed instructions, and with the help of the two ShopBot instructors, participants changed the bit, zeroes the X and Y axes, and placed the material on the machine bed in the appropriate orientation, zeroed the Z axis, ran the files to locate the screw hold position, screwed down the material, and ran their sign file. Safety precautions were emphasized, an instructions on how to “Air Cut” a file before actually placing the bit in the material saved at least one router bit from being set down onto a screw and getting broken.
After lunch, Ted Hall, ShopBot’s Founder and CEO, gave a brief talk about ShopBot’s origins and capabilities. He brought over a Handibot, ShopBot’s newest product, and talked about FabMo, the open source Control System that is being written in-house. Several teachers/students talked with Ted while others finished their sign projects.
Ted Hall, Founder and CEO of ShopBot, gave a brief history and philosophy of ShopBot. Samples of items created with a ShopBot abound in the training area and throughout the company.
Once everyone in the room had completed their first project, the afternoon was open so as to give demos and information on how to successfully use the software or set up the machining files in the way that would be most useful for the individual teacher and student. Importing 2D and 3D designs created in another CAD software, feeds and speeds and bit selection for different materials, how to create an array of holes for cabinet making, and how to use the Rotary Indexer were among the topics touched upon. Participants left with a notebook full of instructions, and ideas for lesson plans and 2D & 3D projects that link to Common Core and Next Generation Science Standards.

In this setting, students and teachers worked side-by-side to master techniques unfamiliar to both of them. The introduction of new technology often goes more smoothly when teachers are comfortable letting students take the lead in mastering new techniques and then sharing that knowledge with others. As the only teacher there with experience using the ShopBot, Mr. Ramsey proudly showed off pictures of the intricate signs that a young woman in his program had designed in Vectric’s VCarve Pro CAD/CAM software and machined on the ShopBot. She used the tutorials and videos available on the ShopBot and Vectric software websites to teach herself, and then others, sophisticated ways to import bitmaps (photos), trace them, and toolpath the designs. One of her files took five different bits, and the use of the ATC let her finish the project within one class session because she didn’t have to stop the ShopBot, then physically change the bit and re-zero the Z-axis in between the separate toolpaths. Mr. Ramsey also learned that it is important to have students from several grade levels work together so that his “experts” don’t all graduate at one time, and he has to start from scratch the next year.
At the end of the day, Mrs. Harris remarked that she was now more comfortable with the machine. SHe saw that there were many similarities to the 3D printer that she had used at the North Carolina Central University FabLab over the summer. Mr. Lee was not one of the teachers who had been given the gift of a ShopBot CNC, but left with information on what size ShopBot he would like to add to his classroom so that his AutoCAD students could actually prototype and test some of the designs that they had created on the computer.
A side note: many ShopBot employees attended local high schools in the counties that surround ShopBot headquarters in Durham, NC. Job positions range from Production through Engineering and Product or Software Development. Some employees started right out of (or even part-time during) high school, and some had internships at ShopBot before finishing their post-secondary education. Below are summaries of the journeys of three such employees:
Al Nyonteh, one of the instructors for the training, attended Riverside High School up to 1997 then transferred to a military school (Tarheel Challenge) for at-risk teens. After graduating in 1998, he studied architectural technology (a drafter that specializes on the architectural side of building construction) at a two-year college in Minnesota. Al worked in a commercial architectural firm for two years (in MN) and with an electrical engineer to create the drawings for the relocation of the electronics department at Circuit City (in VA). After moving back to NC, he worked as an independent contractor to prepare evacuation plans and submit health department drawings for group homes/alternative living facilities. Al joined the production team at ShopBot in 2014. He is motivated to learn everything about running a ShopBot, and often uses his lunch period and after-work time to design in VCarve Pro and machine on the ShopBot and Handibot. His gentle way of working with people and sense of humor make him a go-to person for in-house trainings, and when someone is needed to represent ShopBot at shows and Maker Faires.
Al Nyonteh, instructor, attended Durham Public Schools. He studied architectural technology in a two-year program in Minnesota. Al joined the production team in 2014, and is “fluent” in AutoCAD VCarve Pro CAD/CAM software, and running ShopBot tools using both ShopBot and FabMo control software.
Matt Schmitz went to Durham School of the Arts, where he studied sculpture and theatre tech. He says it was a great place to learn about creative thinking and iterative design. Sculpture and theater tech led to an interest in product design. Matt studied Mechanical Engineering at Brown, graduating in 2014. In 2012, as a sophomore in college, he interned at ShopBot, and worked with CEO Ted Hall to develop the first functional prototype for the portable CNC that would become Handibot. He interned at Google during his senior year, working on the Nest Project (a high-tech smoke/CO detector). He currently works in Product Development, developing the next generation of ShopBots, and for Production Support, developing tools and solutions for clients with specific production needs.
Matt Schmitz, an engineer with ShopBot working in Product Development and Production Support, studied sculpture and theater tech at Durham School of the Arts. While a student in Mechanical Engineering at Brown University, he did internships at ShopBot and Google.
Lee Beatrous attended Cedar Ridge High School (Orange County, NC), taking two years of woodshop class with instructor Keith Yow. Lee furthered his education at Appalachian State University. He started with a focus on Business Marketing but changed direction by entering ASU’s School of Technology and earning a BS in Industrial Design. After winning a Popular Design Vote at the High Point Furniture Market in a sponsored studio competition, Lee went on to work for GSI – a furniture manufacturer in Dallas, TX. He held the position as Project Design Manager for five years. Lee is currently working for ShopBot Tools at Handibot as a Manufacturing Engineer, seven years after working a summer internship at ShopBot in the Production department.

Catching Up with the NODUS Team
When we last checked in with Gustavo Bonet and the NODUS crew, they were using digital fabrication to realize project visions that ranged from architecture to furniture to art installations. In that time, NODUS’ reputation as a “fixer” has grown, allowing the team to move into a new space in Manhattan’s SoHo neighborhood that simultaneously serves as a gallery, collaboration area, and workspace. The space is designed to embody NODUS itself, reflecting the changing idea of what a workspace can be. For NODUS, this move doesn’t mean a change in the type of work they do, it just means more flexibility and fewer obstacles, and increased notoriety in the digital fabrication and design communities.
The New Space
The SoHo space will house the NODUS team, host alternative events, and display finished works. In addition, it will allow the team to explore new avenues in design, architecture and art. One of the scheduled events, for example, will feature a pastry chef who will explore the idea of the modern kitchen. With projects like these, Bonet’s team is focused on pushing boundaries. “We’re thinking outside of the box, and we’re at the cutting edge as far as workspaces go, transcending the realm of furniture or industrial design. It will feature things that will enrich your day. We’re catering to things that stand out.”
A Unique Take on the Design Process
On a day-to-day basis, even the role that their ShopBot plays in the process is unique. It’s seen less as a mass-production tool and more of another potential solution to meet the needs of the project at hand:
“We’re architects using the tools in a very hybrid way,” says Gustavo. “We’ve learned the basic commands and can approach projects from a problem-solving architectural standpoint. With proximity to the tools, adjustments can be made on the fly. We’re bridging the gap between art & architecture.”
The bOcean resort lobby reception wall was inspired by blades of seaweed swaying in the ocean.
One of the best examples of such a project is the lobby reception desk installation at the bOcean Resort in Fort Lauderdale, FL. Charged with designing a carved wood installation that would mimic seaweed swaying in the ocean, the NODUS team also looked to complement the art deco and features dotting the resort, as well as the storied mermaid show featured at the lobby bar, from where the upstairs pool is visible.. Their solution was an 8’ x 24’ surface comprised of 21 individual pieces, each cut on the ShopBot and assembled on-site like a large puzzle.
The Dwana Smallwood Performing Arts Center
With projects like the Dwana Smallwood center, NODUS is re-thinking the way CNC can be used for design.
For the Dwana Smallwood Performing Arts Center between the Brooklyn neighborhoods of Bushwick and Bedford-Stuyvesant, Nodus worked with architects at JPDA to develop a surface relief for the facade and interior echoing the rhythmic quality of a dance gesture rippling out, impacting its surroundings.
For the interior reception area, Nodus milled solid fiberboard panels tightly coordinated with the surrounding millwork for seamless integration. On the exterior facade, custom-cast, glass fiber-reinforced concrete panels provide graphic identity for the dance center, and continuity between exterior and interior.
For interior panels, Nodus prepared fabrication models, and surface milled fiberboard directly. For exterior panels, concrete forms were developed through an analogous process, then cast by hand.

Hines Fischer Furniture Prototypes
For the ICFF Studio 2015 Competition, Nodus worked with industrial designer Hines Fischer to fabricate prototypes for his Minun series. Nodus performed two-sided milling of all wood components and joinery included in the piece.
Two-sided milling of furniture pieces created a 3d effect.
Designing the Future
As to how NODUS sees future projects taking shape, it’s all about staying innovative.
“There’s no limit,” says Bonet. “It’s the idea of a workspace that’s changed, and it’s truly a collaborative environment/gallery/showroom. We’ve become the keystone of the industry, and what is rewarding is we’re seeing more and more people starting to respect and appreciate our role in the process.”
The NODUS team may be beginning the next chapter of their story with the SoHo gallery, but the main theme is always going to be collaboration and problem-solving. You can check out their latest projects on the nodusNYC website & Instagram, and stay tuned to ShopBot Tools for the latest updates!
TechShop DC/Arlington served as a great host location for the first ever DC-Arlington Camp ShopBot. Situated across from Reagan International Airport, a large and varied population utilizes the space and tools. And with three different models of ShopBot machines and array of other machines their members are not lacking in digital fabrication resources. One can tell that Gadsden Merrill, General Manager, and his staff work tirelessly creating an energetic environment.
The ShopBot team comprised of Sallye Coyle, Reggie Riddit, Thea Eck, Bill Young, and guest presenter Andy Pitts. Attendees drove in from as far away as Eastern PA and also from Baltimore and the surrounding Virginia communities. Experience ranged from absolute beginner to professional user with years of CNC practice, many types of material cut, and multiple Camps attended. And being at a makerspace, curious TechShop members popped in and out all day.
Sallye began the day discussing CNC and CAD/CAM along with the cache of digital fabrication tools now available to the average maker that aid in prototyping or embellishing projects. Thea then lead the group in several presentations including highlights of Vectric’s new Aspire 8.5 and how to calculate the dreaded feed rate and speeds for a project. Sallye showed some hidden gems in the SB3 software, which are often overlooked or not fully understood. Lunch gave everyone the opportunity to mingle, look around TechShop’s studios and talk one on one to ShopBot staff.
Following lunch, the Show and Tell session offered a few volunteers the chance to present their projects. Andy Pitts then launched into the afternoon presentations explaining how to set up a CAD file and then machine a two-sided bowl using Aspire software. Though simple upon first inspection, this complex bowl shape utilizes multiple two-rail sweeps and 45° 3D machining techniques. Sallye and Thea followed up with two presentations on 3D machining: 3D scan to 3D machining and practices in 3D designing/machining starting with the basics such types of bits and understanding stepover rates.
Bill Young discussed and then demoed FabMo, a new development currently used to operate the Handibot. Bill chimed in throughout the day with his expertise on a variety of material, software, and machining topics. The final presentation, machine maintenance and troubleshooting, got everyone out of their seats and crowded around TechShop’s PRS Alpha 4×8.
Like many Camps, the day sped by. Often times conversation came back to pricing items and calculating costs: electrical costs, material costs, production vs. custom items, how much to pay oneself and working with clients. Everyone seemed to gain new insight, some ‘hidden gem’, personal to them that will hopefully make machining or designing a little easier.
Thank you to the TechShop DC/Arlington staff and to the attendees for spending their Saturday with us.

Friends from 5 Continents sharing one last evening at SZOIL after Fab 12 in Shenzhen.
The Location: This year’s gathering of the International FabLab network took place in early August in Shenzhen, China. About an hour from Hong Kong, Shenzhen is a new city, grown up in the last 25 – 30 years from a fishing village to a modern industrial and commercial center. Except for the signs in Chinese characters, the view from my room on the 22nd floor of a hotel in the financial/convention district looked more like an American city than many international cities built on top of older civilizations: traffic was organized in proper lanes, turns signals flashing, horns blaring. Shenzhen’s location close to Hong Kong, the numerous factories to manufacture whatever it is you need, and the amazing network of creative spaces around Shenzhen made it the perfect location to hold the meeting.
Those FabLabbers with a bent towards creating their own could fill a suitcase with motors, drivers, boards, cables, or purchase real or knock off phones, cameras, projectors, and watches in the electronics markets. The shopping malls carried name brand clothing, shoes and purses from around the world, as well as motorized carts in the shape of animals for the kids to ride around the mall. Many malls had DIY sections, with build-your-own music boxes, pottery wheels, and painting classes. Grocery stores had Lays Potato chips bags with funny faces on them, cans of soda with the name in the familiar Coco Cola font as well as Chinese Characters, Dragon fruit, and chickens with head and feet still attached.
It seems that the crane is the national bird.

Sunday afternoon at the mall is a family affair
The Meeting: The annual Fab gathering is an important vehicle for building and maintaining the network of FabLabs. It is also a celebration honoring the graduates of Fab Academy, the 6 month long course based on MIT’s “How to Make (Almost) Anything.”
Mornings were filled with reports on the doings of FabLabs around the world, and announcements of interest to the greater community. And there is always Fabbercise, which can have its own share of familiarity and hilarity.

Afternoons brought options for workshops and sessions. Want to use a laser cutter to create hats or lamps? There’s a workshop for you. Want to discuss topics in education or humanitarianism? There’s a session for you. Want to catch up with old friends and make new ones? There’s plenty of time to connect, collaborate and share. Evening meals and after gave more opportunities to learn what is happening in FabLabs around the world. There was even the opportunity to see how products developed in a FabLab can be brought to market when 3NOD, one of the event sponsors, hosted a fabulous evening at their headquarters.

The focus of Fab12 was FABLAB 2.0, the ability of a FabLab to use its own digital fabrication tools to produce a fab lab and to produce the manufacturing machines of the future. Since the Handibot (www.handibot.com) was inspired by work of MIT students under the direction of MIT Professor Neil Gershenfeld, Center for Bits and Atoms ( www.cba.mit.edu ), it seemed only proper that a Handibot traveled to Shenzhen to take part in the festivities. Others brought their version of a digital fabrication tool created in a FabLab. Jens Dyvik used the ShopBot in the Shenzhen Open Innovation Lab (SZOIL) to fabricate parts for his VBird parametric CNC, and Steven Sui made his multipurpose CNC machine with GCC products such as the laser cutter and CNC machine. Nadya Peek offered workshops on how to create digital fabrication tools from cardboard kits and component motors and rails.

The Symposium: Friday’s symposium, open to the public, addressed 4 topics that scaled from the individual to the civilization.
- Systems That Make Systems
- Businesses That Make Businesses
- Organizations That Make Organizations
- Civilizations That Make Civilizations
The Fab Festival: The weekend event, open to the public at the Civic Center, was a celebration of all things Fab.
FabLabs in Peru are working with indigenous people to retain knowledge about such skills as weaving and furniture making. There is also a floating FabLab on the Amazon River.
FabLabs in India range from those at an Engineering University in Mumbai to an Ashram in the country that emphasizes project-based learning. Projects include how much it costs to raise animals, or create machinery that enhances lives. In Kerula, there will be 20 mobile FabLabs distributed around the province, each with a ShopBot Desktop.

ShopBot Sallye at Fab 12:
ShopBot and FabLabs have had a strong relationship for a number of years. ShopBot is a CNC of choice on the official FabLab buy list, so attending the Fab meetings is an opportunity to keep up with the exciting advances that those who participate in the FabLab network are making, offer training and tech support where needed, and learn what ShopBot needs to pay attention to in order to better serve the community. After 6 years of working with FabLabs, I feel that I have a growing network of contacts that works both ways. If someone has a question, they have my direct email and a cell phone number to call. Likewise, if a ShopBot user or ShopBot Tech Support needs a local representative to serve as “boots on the ground”, I have an idea of who has ShopBot experience that we can reach out to. Our plan is to expand that network and make it more accessible…look for an update to the ShopBot website in a few months.
It is always a bit surprising when someone refers to ShopBot as a “vendor”. We think of ourselves as friends and colleagues who just happen to manufacture an amazing CNC machine. Arriving a few days before each meeting is an opportunity to make new friends, pay attention to how people are actually using the machines, as well as to make sure that the local ShopBot is in proper working order for the meeting. For Fab 12, the ShopBot at SZOIL was mostly assembled, but Francisco S (Beach Lab, Sitges, Spain), Vicky (SZOIL) and I spent several hours resolving some Control Box/Spindle issues before laying down the support and spoil board. Since Francisco will be one of the trainers going to Kerala, India, to help with their deployment of 20 mobile FabLabs, he got some hands-on experience with hardware and software. Vicky, Fab Manager at SZOIL, began to take ownership of her ShopBot when she used a ratchet wrench for the first time to tighten the hardware for the support board. We ended the late night by taking a 3D scan that Vicky had created for printing on the 3D printer and machining it on the ShopBot.
With each international trip, I learn a bit more about how ShopBot is used outside of the US. Some lessons are not related to the ShopBot itself, but point out differences in the operating language of the computer, or electricians deciding to run the power to the control box in a way that does not conform to the specs of the tool. It can be a lesson about the types of material available locally. For example, in Shenzhen, there were two different kinds of sheet goods available in the lab. While both were referred to as “plywood”, they had very different characteristics. What I would call “plywood” is made up of thin layers of wood laid down with the grain rotated 90 degrees at each layer (ply). It is less resistant to changing size as the humidity level changes, and maintains a certain level of structural when dadoes or slots are machined into it. Sheet goods that are made up of long strips of solid wood glued up and covered with thin veneer may be more consistent in thickness than plywood, but it can lose its structural integrity as soon as the thin veneer has been machined through. I have never seen this type of sheet good in the US, but have now found it in Japan, Egypt and China.
Vicky, Fab Manager at SZOIL, tightening down the ShopBot support board.
Vicky’s first project with the ShopBot. She added bunny ears to the original .stl created from a 3D scan, then carved it on the ShopBot with a .25 ball nose bit. See our previous blog entry for the process to convert a 3D scan to a 3D ShopBot carving.
With “plywood” (above), thin layers of wood are peeled off of a log, laid down flat and laminated together. One does not have to pay attention to the grain of the sheet good when assembling cabinets or tables, since the grain of each “ply” is alternated 90 degrees to reduce the effects of changes in humidity level on size of each component.
The second type of sheet good is made of up solid strips of wood that are glued up the length of the board. Note the growth rings on the edge of the board. Only a thin layer of veneer adds strength to the glue up. Creating a dado or machining a hole/slot in the material could result in compromising the integrity of the sheet good because it could weaken where the strips are glued up.
There’s too much to talk about for me to put it all in this blog. Visit the Fab12 website, and look up Fab Foundation, Center for Bits and Atoms, and FabAcademy for more information on the wonderful things that are going on with the 1000+ FabLabs around the world.
From the time we first started, sharing has been an important part of ShopBot’s DNA. The files to build a ShopBot were originally released by Ted Hall as shareware and there have been a steady stream of project files available since then. The fabrication files for one of my first projects, “Honey’s Canoe,” have been available in various forms for 20 years, and are thought to be the first DIY CNC project to be shared publicly. Unfortunately, the infrastructure for sharing wasn’t quite up to the job in those days, so for the first couple of years we had to send all our files by mail on floppy disks!
We all learned to share in Kindergarten, it’s one of the most valuable things you’re taught. If you had a cookie and gave half to your friend, you’d be a better person for it. When you got older you might share a book or tool by lending it to someone. Sharing was easy, first the thing was yours and then someone else had it. You might get it back, but you couldn’t both have it at the same time.
Sharing became more complicated when things became digital. You could share something and still have it! Since the cost of making a copy of a digital file is functionally $0, you would think that sharing something you created costs you nothing. To do it right though there is a cost: a cost in time. Here are some things to think about when you are considering sharing a project:
Let me start by saying that I AM NOT A LAWYER and that this is just a layman’s understanding of a very complicated subject. Do your research, there are lots of resources on the web including the Creative Commons website.
With that out of the way, even though you may think you are sharing a thing—a chair, a table, a sign—what you’re really sharing are the files that describe that thing. The photos, CAD files, CNC part files, everything that tells what it is and how to make it. In the early days, we just made files available and basically said “have at it,” thinking that was all we had to do to make them useful. In the US and most of the rest of the world, all your files have been automatically copyrighted without you having to do a thing. No one can really use them until you add an “open license” that spells out the conditions that you place on using and distributing those files. This protects anyone that uses your files and prevents you from coming along in the future and saying “You didn’t have permission to use my files.”
Because of this automatic copyrighting, you have to assume that a file is protected by copyright unless an open license is attached to the file in some manner. It varies with the license, but generally there is either a file included with a project download that contains the terms of the license, or there’s something describing the license that you have to agree to before you download the file—and that license has to accompany the files any time you share the original files.
The Creative Commons folks do a great job of explaining how their licenses work, but here are a couple of terms and options that you should consider when deciding how to license your project files. Be aware that you can mix and match them to get just the combination that suits you :
Public Domain: You are giving the files to the public and anyone can do whatever they want with them.
Attribution: If someone shares your file they have to give you credit.
Share-alike: Any copies or modifications to the files have to be shared with the same or similar license.
Non-derivative: Anyone using the files can modify them for their own use, but can’t share their modified version and only reshare your original files.
Non-commercial: Your files are available for personal use, but can’t be used commercially without permission.
I know this is complicated and can be kind of a pain, but this licensing business is really important to understand before you decide to share files. Now, on to the nuts and bolts of sharing…
Files and formats:
The whole point of sharing projects is for them to be usable by someone else, and your job is to make it as easy as possible for people to fabricate your project. That means including files in formats that make it easy for the largest number of people.
We all love Vectric software and ShopBot includes it with all tools, so including those file formats is probably the most helpful. They let the end user make modifications to both customize the cutting to fit their particular tool and cutting style, and to make the project better suit their needs.
There are, however, ShopBotters and Handibotters that …gasp!… might not use VCarvePro or Aspire, or haven’t kept their copies up to date. That’s why we also recommend that you include an additional format or two—for those folks. A common vector format like .dxf , .dwh, .eps, .ai, or .svg works well for 2d cutting, and .stl is pretty universal for 3d models.
What about ShopBot .sbp files? It’s certainly helpful to include them and they make a lot of sense for things like Handibot projects where all the tools are the same size with the same cutting capabilities. If you include ShopBot files though, try to make sure that the cutting speeds and pass depths are on the conservative end of the spectrum.
Creating instructions is a lot of work and not much fun, but there’s some information that people just need to know. Details like materials, bit size, and any extra supplies that are needed. So at the minimum, please include a readme.txt file that includes that information and hopefully a little about yourself and how someone can contact you with praise (and questions). For anything but the simplest projects, including a little more complete set of instructions—maybe with some pictures—will be very helpful. And just like design files, use formats that are universal and accessible like .pdf and .html.
Storage and Updating:
Very few designs and projects are static, and almost all (hopefully) improve over the years. Keeping the online version in sync can be tough, but is really important. Lots of projects including Shelter 2.0 and Handibot use Github as a “repository,” but in general it was designed for software projects and is pretty tough for many people to use. DropBox is another option for storing and sharing files, and there are lots of tool-specific sharing sites like Handibot.com.
We all think we come up with project designs as a flash of inspiration and brilliance, but in reality they are almost always a composite of ideas that you have seen over the years. It’s often hard to place exactly where that inspiration came from and we all suffer a little from kleptonesia, defined in the Urban Dictionary as “(n.) condition characterized by forgetting the source of a stolen idea,” but it’s always better to err on the side of giving too much credit rather than not enough. If someone or something inspired you, make sure that you point that out!
Please don’t let all of this discourage you from sharing the things that you do. My intention is to make sure that when you do share files and projects that they are really useful to the end user, because that’s what it’s all about!
On a recent Professional Development session (PD) at the Chevron FabLab at California State University Bakersfield, Caroline McEnnis and Sallye Coyle of TIES (www.TIESTEACH.org) spent three days working with teachers, interns and staff to give them more experience with the digital fabrication tools and electronic components available in their Lab. Caroline had the attendees use a Kinects to scan themselves in 3D, then had the 3D printers print out tiny plastic versions of the scans. Later, Sallye showed the teachers how they could do more than print their 3D file (.stl) on a 3D printer. She had the teachers bring the models through VCarve Pro to create files that could be machined in wood on a ShopBot CNC.
3D printers printing heads scanned with a Kinect while teachers work on another project
Three of the scanned faces on a 2 x 6 board after running the roughing phases
Finished model with the original. Resolution was determined by the resolution of the scan, how the .stl was scaled from the original, and the size of the bit to carve the file (.25″ ball nose).
This is not a full tutorial, but an example of the steps we went through to machine the images in 2″ x 6″ boards. What could a teacher do with this? How about creating a totem pole with each student’s image as a class project? What can one teach about history and culture by studying totem poles? Are the more important images placed at the top of the totem pole, or at the bottom?
- Create the scan: The Internet has information on how to connect a Kinect to a PC to create a 3D scan. Here is one option. Virtually any 3D scan that creates an .stl would be appropriate.
- Bring the .stl into VCarve or Aspire (NOTE: version of VCarve Pro must be 7.5 or later):
- The HELP file in VCarve and Aspire is excellent; please refer to it in detail. The HELP is bookmarked, so when you click on the item you are interested in, it will go to that page.
- By clicking on the MODELING tab at the bottom of the left hand screen, you will see the options for working with a 3D model or component such as an .stl.
- When you import a component, you can choose what orientation to import the data. Keep clicking until you have the front view of the scan face up in the material.
- Change the view to the side view, and slide the bar until you have most of the image that can be machined from the top down (no undercuts). Delete the data below zero if you are only going to machine the face. If you want to do 2-sided carving, create both sides then separate the two 3D components for machining separately.
- You can only import one .stl at a time into VCarve Pro, so you may have to open a separate session of VCarve Pro for each face. As long as you know where to place them on the board, you can then machine them as needed (try putting a rectangle where each of the faces would go. You can then copy a vector or component from one session of VCarve/Aspire, then paste it into the same location on another session).
- Lay out the components on the virtual board, then toolpath them
- In the image below, the first of three 3D components laid out on the virtual representation of the board measured 24″ in the X (arbitrary length) x 5.5″ in the Y x 1.5″ in the Z (standard measurements of a 2″ x 6″), with the Z zero set to the top of the material. The component was placed in the center of a rectangle that was placed on the board. A second rectangle was also placed on the board to mark the location of a second 3D component.
- The height of the model was reduced to fit onto the thickness of the board. A model that has been flattened so that it keeps the features of the full 3D but would not be as thick as the original when viewed from the side is called bas (pronounced “baa”, French for “low”) relief.
- Select the rectangle surrounding the component and set the roughing pass. In this case, a .25″ end mill bit was used for the roughing passes. The screen below shows both 2D and 3D views. The 2D (left view) shows the placement of the component surrounded by a rectangular vector. The 3D (right view) shows the 3D rendering of the component with the roughing passes overlaid. The CAD menu screen (left side) and CAM menu side (right) are also shown. The 3D toolpathing options are circled.In this first sample for the 3D finish pass, two bit options were tested (virtually). While the .125″ ball nose bit would give more detail, it would take more time to machine than would the .25″ ball nose bit.
- Create two toolpaths, one for each bit. The use the icon that looks like a clock to see the estimated time for each of the toolpath options.
- Use the Preview icon to look at each of the toolpaths. Remember to reset the preview in between testing the toolpaths. This particular model does not really need the detail from a .125″ bit.
- Save the roughing and finish toolpaths (use the “floppy disk” icon)
- Save the roughing pass separately from the finish pass.
- Give each toolpath a name that you can remember later (you might include name of person scanned, roughing or finish pass, type of bit used, etc.).
- Do the same for each of the other faces
- Prepare the board for machining on the ShopBot
- Photo below shows board after faces completed how the hold down was placed outside the area of travel for the machining.
- The board was placed on the table so that the bit would not go outside the range of travel in the Y-axis (board moved away from the long edge of the table).
- Holes for screws to hold down the board were drilled before sheet rock screws were screwed through the board down to the sacrificial board under the 2 x 6. The length of the design area was measured (24″), and the screws placed outside that design area. See red oval for placement of screws at the top of the board.
- The X and Y axes were zeroed at the point where the first face would be machined to further ensure that the bit would not hit a screw while machining the file. Arrow points to where bit was positioned at place where file would start, then the Z2 command (or button on keypad screen) used to set that location as X and Y zero (0,0).
- Run all three roughing passes
- Run each of the ShopBot (.sbp) files that use the .25″ inch endmill to rough out the faces, one after the other
- Change the bit to the .25″ ball nose bit and do the finish passes, one after the other
- If necessary, use the scroll saw with a blade (or the band saw) to cut the faces into separate blocks
Other options for using 3D models:
- Take the file through 123Make to turn a 3D model into 2D build plans. Photos below show a 3D model of a boat “sliced” and machined in wood on a ShopBot and in acrylic with an Epilog laser cutter:
- In the example below, a CT scan of a duckbill dinosaur skull was taken through Rhino, then Aspire CAD/CAM software and “sliced” into 2″ thick panels of pink insulation foam which were machined on both sides. The sinuses and larynx were printed on the 3D printer, the whole thing reassembled, and a Ph.D. student used it in her dissertation:
Larry Sears and Sally Zlotnick Sears think[box]
is arguably one of the largest and most dynamic maker spaces in the country. think[box] is located at Case Western Reserve University’s Center for Innovation and Entrepreneurship, and provides a space for anyone – students, faculty, and alumni and members of the community – to tinker and creatively invent. Housed in a 7-story, 50,000 square foot facility, with 3 floors occupied and more to undergo renovation soon, this $35M project is one of the largest university-based innovation centers in the world. By numbers, think[box] receives over 5000 visits each month!
I recently spoke with Marcus Brathwaite, a Lab Technician at think[box]. One of Marcus’ responsibilities is to train people in use of the full size ShopBot tool in the maker space. Marcus graduated from the Cleveland Institute of Art in 2013 with a B.F.A. degree in Ceramics.
As a member of the team his mission is to bridge the gap between science and the arts by facilitating and developing art experiences in and around think[box]. His artwork investigates the past, present and future of human relationships to technology. Marcus said, “I was first exposed to the ShopBot when studying at Cleveland Institute of Art, which introduced art students to tools more commonly used by engineers. I visited Case Western to fabricate my art projects.”
think[box] serves students, alumni, and the public at large. The vast majority of users are students of mechanical engineering, computer science, biomedical engineering or aerospace engineering. Marcus said, “They use the ShopBot for project work — they all take 3D modeling classes and use SolidWorks primarily. The ShopBot is one of our most popular tools. I train folks to run this and other tools.”
Overall, noted Marcus, “the projects made here range from artistic to engineering-focused.” Here are just a small sample of the projects which make use of the ShopBot:
Portable Proximity Card Reader (a new-fangled ‘people counter’) In an effort to streamline the process of checking students in at large events, Case Western’s Student Affairs IT office has designed and made several hand-held proximity card readers compatible with Case ID’s. This completely in-house design costs less, has a greater capacity, and is significantly faster than the previously used magnetic stripe card readers. The ShopBot was used to mill a wooden mold for the thermoplastic clear cases of the counters.
Jaswig Students from Kent State milled all the pieces for prototyping this adjustable-height stand-up desk. It is now being used in homes, offices, and schools around the world.
Condado Tacos This custom exterior signage for Condado Tacos in Columbus, Ohio was made from SignFoam on the ShopBot with a v-carve bit.
Custom-built CNC router This 3-axis CNC table router was designed and built from scratch by students from the University of Akron. Fabrication occurred at think[box] where parts were cut using the ShopBot.
Mini Baja Car This vehicle competed in the Society of Automotive Engineer’s annual mini-baja competition where CWRU students designed and built the car from scratch. Although primarily fabricated in the Bingham Machine Shop, many supplemental tasks were completed in think[box]. In particular, students 3D printed mold-making patterns, cut out welding fixtures in the laser cutters, and fabricated composite floor panels for the finished car on the ShopBot.
Reading Wetu “Reading Wetu” is a project created with the first grade class of Ms. Erin Shakour at Orchard STEM School located on Cleveland’s westside during the fall 2014 semester. The reading Wetu occupies an 8′ x 8′ x 8′ area in the corner of her classroom, and houses her small library of children’s books. The structure is built entirely from 3/4″ thick plywood and yarn, and fabricated with the CNC router at think[box]. This project is part of a series of works that Marcus created in collaboration with Progressive Arts Alliance, a local arts organization whose focus is to provide STEAM (Science, Technology, Engineering, Arts, and Math) programming to the Cleveland Public School District.
I asked Marcus how students react to being introduced to the ShopBot and what it is like for them to use the tool. Marcus said, “They begin with a total fascination and awe about it, watching the tool move and cut projects. Even though CNC is an older technology it never ceases to engage interest of the new students.”
The next phase is one of “some intimidation,” noted Marcus, when students begin to understand the steps needed to get up and running. “Once they dive in and read tutorials and start using Partworks, it starts to become easier for them,” he added, “because they see that Partworks is much like software that they’re familiar with. The tool is well designed and intuitive to use, so once students get familiar with the software things become much smoother for them.”
We look forward to seeing a lot more uses for the ShopBot coming out of this amazing space!
