It’s my belief that history is a wheel. “Inconsistency is my very essence” -says the wheel- “Rise up on my spokes if you like, but don’t complain when you are cast back down into the depths. Good times pass away, but then so do the bad. Mutability is our tragedy, but it is also our hope. The worst of times, like the best, are always passing away”.— Boethius, From 24 Hour Party People

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
