Please read the instructions that come with your HobbyCNC controller/motor kit very carefully. Here are a couple of gotchas that we found through trial and error:
- Watch your jumper settings, especially when setting Vref. These must match the software settings in EMC2.
- Install a bleed resistor on the big capacitor, and do not touch any part of the electrical system unless this cap is fully discharged.
- Install a power LED/1k resistor (not included) between 5V pad and ground on your board. This also shows you the status of the big cap.
- Use consistent motor wire coloring.
- Do not plug/unplug wires until the system has been powered down for a couple of minutes.
- Take the time to build a case. Good airflow for cooling is critical.
- The included power switch is meant for much smaller wires. Purchase a beefier one and throw the stock part out
- Solder all three drive chips to the board, then hold up the heat sink to mark all 6 drill holes at once. If you lay these out with a square beforehand you’ll never get the alignment right.

Chris will talk about the DIYLILCNC project, an open source set of plans for a low-cost, easy-to-build robotic fabricator. Specific topics will include: crowdfunded hardware development; the upcoming release of version DIYLILCNC v2.0–aka the BigShoulder; an in-progress software development project aimed at fostering open-source physical design & hacking collaborations.
The main goals of dorkbot are: to create an informal, friendly environment in which people can talk about the work they’re doing and to foster discussion about that work; to help bring together people from different backgrounds who are interested in similar things; to give us all an opportunity to see the strange things our neighbors are doing with electricity. dorkbot isn’t really a forum for formal artist talks or lectures, but rather a chance for diverse people to have friendly conversations about interesting ideas.
Get up close and personal with a DIYLILCNC in action! Taylor and Chris will be running demos, answering questions, and having fun at Maker Faire NYC 2011.
Saturday, Sept 17 10 a.m. – 7 p.m.
Sunday, Sept 18 10 a.m. – 6 p.m.
Organized by the staff of Make magazine, makezine.com and craftzine.com, Maker Faire is a newfangled fair that brings together science, art, craft and engineering plus music in a fun, energized, and exciting public forum.
The aim is to inspire people of all ages to roll up their sleeves and become makers. This family-friendly event showcases the amazing work of all kinds of makers – anyone who is embracing the DIY spirit and wants to share their accomplishments with an appreciative audience.
The next Open Hardware Summit will be held on September 15th, 2011.
Taylor Hokanson will host a breakout session covering open-source DIY CNC technology, and Chris Reilly will conduct a live demo of the DIYLILCNC and open-source CAD/CAM software.
The Open Hardware Summit is the world’s first comprehensive conference on open hardware. The Open Hardware Summit is a venue to discuss and draw attention to the rapidly growing open source hardware movement. Speakers at the Summit include world renowned leaders from industry, academia and the DIY community. The summit focuses on hardware as a system through a series of discussions and panels on BUSINESS, LAW, MANUFACTURING, SCALING, DESIGN and EDUCATION. The one-day Summit seeks to empower companies, large and small, to produce electronic objects in an open source fashion.
Sunday, August 7: noon – 5:30 pm
Monday, August 8: 9 – 5:30 pm, 9 – 11 pm
Tuesday, August 9: 9 am – 5:30 pm

The Studio is the place for making and creating at SIGGRAPH 2011. Roll your sleeves up and get hands on in this three-ring circus of technological wonders. It is an amazing space where experts, attendees, and the latest technologies are brought together to create new works, experiment, and collaborate. Leave your old work behind, come to The Studio, and create something new.
In the Studio, you’ll find technologies specifically set up for you to use and create with. Our experts make special arrangements with research labs, developers, universities, and vendors to provide access to technologies that are not easily accessible elsewhere. Attendees can experiment and create new works with large-format printing, motion capture, interactive music, the latest software suites, high-end computing workstations, laser scanning, and many new additions to The Studio.
More than ever before, the Studio is for people of all ages, interests, and disciplines who want to create new works. You’ll see kids making their own creations, live interactive music on our stage, in-depth workshops in our classroom, attendees working with Emerging Technologies presenters and Art Gallery artists, and wearable technologies on attendees. It’s a fun space, a creative space, a learning space, a discovery space, a space for you.
