The proper function of man is to live, not to exist. I shall not waste my days in trying to prolong them. I shall use my time.— Jack London

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
