I needed a better CNC router so I took to FreeCAD to create a workable design. I sourced up all the parts and welded the frame together. I slapped a 6-axis GRBL build onto an Arduino Mega 2560, piped it into a breadboard and out to some Nema23 steppers. They roll through 3D printed gears to ballscrews that drive the whole mess.
When it was all done, four months had passed. I routered up some softwood, then engraved some acrylic. I wrote an autoleveler into my CNC controller software, then probed and milled a circuit board. Finally, I stumbled through trying to mill 0.25” aluminum with a HSS bit. Darn near didn’t get that done.
In the end, I have a new CNC router that should be more than capable of doing the things I need done for the next few years. I hope you enjoy the video. If you want to look at the CAD file, or try to make one of these, visit this web page:

Good times! Quite an adventure.
