Hi All, I'm new to this forum. I wanted to introduce a new open-source, DIY CNC milling machine project I am just getting off the ground (see
lobocnc.com). It is a lightweight desktop machine that falls somewhere between a CNC router and a more conventional milling machine. I've been using it for making acoustic guitar parts (inlays, carving bridges, cutting blind fret slots, etc.) as well as lots of other odds and ends. It uses closed-loop steppers, and with the feedback, you can easily switch back & forth between manual and CNC machining without losing track of your position. (The encoders essentially act as a digital readout.)
I've got complete drawings, part lists and vendor lists at the Lobo CNC web site. I've got a few sets of the structural sheet metal parts (see photo) done by a local shop that I am selling at cost. You can use it with standard NEMA 17 motors and drivers, but I've also got a custom controller board I designed that supports closed-loop control.
Check it out at
lobocnc.com and let me know what you think.
