This is a 3 axis cnc milling machine that can mill circuit boards as well as aluminum or other soft metals. The software that comes with the planet-cnc controller can generate g-code from dxf or gerber files. The jog pendant allows one to mill manually, with digital readouts of the axis positions on the pc interface.
This mill, like the Pocket Printer, uses the aluminum extrusions as slides. You will need to adjust your printer settings to get a good fit when printing the slides. The exploded drawing and BOM should give you a good idea of how it goes together. I did not include the screws or other hardware, so you will have to figure those things out. This has not been thoroughly tested, but is working well so far. It is very precise and accurate. I use a tool makers vise when milling aluminum, which adds a lot of mass for smoother cutting. I hope this gives others some ideas for other designs.
I have added a folder with all the Inventor files.
