I’ve always lived cheaply. I live like a student, basically. And I like that because it means that money is not telling me what to do. I can do what I think is important for me to do. It freed me to do what seemed worth doing. So make a real effort to avoid getting sucked into all of the expensive lifestyle habits of typical Americans … because, if you do that, then the people with the money will dictate what you do with your life. You won’t be able to do what’s really important to you.— Richard Stallman (RMS)

I’ve been fascinated with machine tools and mechatronics for well over a decade, and have been indulging that fascination with a series of little benchtop CNC machines since about 2008, especially since my collection of related degrees lend legitimacy to … Continue reading
This was originally posted as Shapeoko: Part 6, because I apparently can’t count. A while ago I ordered a 300W ER-11 DC spindle kit from China to install in my Shapeoko. I finally got to the post office yesterday (stupid … Continue reading
I got some more time to work on my Shapeoko over the last few days, and now have mostly correct 3-axis motion. As before, details under the fold.
Naturally, this post is a follow-on to Shapeoko: Part 1 and Shapeoko: Part 2. I’ve basically put the machine together now, and can move the X and Z axis around from the host computer, but still have to figure out … Continue reading
This continues from where I left off in my previous post Shapeoko: Part 1. I alternated my Sunday afternoon/evening between tackling my grading backlog and building pieces of the Shapeoko. This pattern works well for tapping since they are both … Continue reading
My Shapeoko kit arrived from Inventables while I was away at SC. I’ve been trying to build myself a small CNC milling machine since 2009, and contemplating it for longer than that. It became clear that my original design, however … Continue reading
Another bit of progress on the CNC project: Better drive nuts! The design is attempting to avoid expensive, difficult-to-source, or chicken-and-egg problem machined parts. The biggest issues because of that policy come from the couplers which attach the lead screws … Continue reading
I got a set of RepRap Stepper Driver v.2.3 kits to use for my CNC project, and was having no end of trouble with them, but finally had a breakthrough that has two of the three working…and one definitely, definitely … Continue reading
