Edit: If youre making your own gcode, or drilling your own holes, DO NOT go by the 9mm hole diameter recommended on the packaging of the threaded inserts I used. They are too loose in MDF. Go with 5/16″ / 8mm. I’m just going to throw on a ridiculous title because it looks like no one gets to my videos from my blog. This (last) week I did a quick painfully slow little mod to my Shapeoko 2 where I … Continue reading
It only took 3 weeks, but I now have both a functional Desktop CNC machine and a viable workflow for 2.5-D milling. This video summarizes my journey from a simple SVG made in Inkscape to a milled test piece in cardboard that I will proudly hang in my office.
… and I only ruined one Sharpie. After far more than a weekend of work, I have wired up the Shapeoko’s stepper motors to its Arduino and run my CNC through its first tests. The system has been tuned and calibrated and is now ready for a build. There were a lot of mistakes made along the way however… watch the video for the full story. Too lazy to write a debriefing now.
In case you hadn’t noticed, I was kinda majorly geeking out over this Arduino-controlled machine last week. Over the holidays, the Shapeoko 2 CNC kit I had ordered from Inventables arrived. I spent most of my free time in the beginning of January putting together my first serious workshop toy/tool. I documented the entire process as well as I could (I was far too busy trying to make sense of all the metric hardware) and summarized the entire process in … Continue reading
After a ton of procrastination this weekend, I finally got around to setting up stage 1 of my motion control contraption. Using a simple Arduino program to step forward and backwards in a loop, I got a few test shots with my Nikon bolted to the rig. The shutter was triggered via the Arduino to prevent the camera from taking a picture while the rig was in motion. The resulting stitched video is by no stretch of the imagination smooth, … Continue reading
Just to prove that I haven’t been only playing video games, I humbly present to you a simple opto-isolator test circuit. This is the first step to remotely triggering my camera’s shutter remotely without putting it in any danger of a voltage spike from the rest of my motion control system and Arduino. The optocoupler is essentially a light-driven transistor with no physical link between the input and the output. The next step for me is to wire this up … Continue reading
