CNC Machine Prototype
This is a proof of concept CNC machine I built, really just to see how hard it would be and so I could learn what not to do for version 2 (which is in the works). It is created from almost entirely salvaged parts, mostly from old scanners and printers which use highly accurate stepper motors to move their print heads. I have now added larger stepper motors to the X and Y axis. This machine is really only capable of milling soft materials like foam and wax but it does it very accurately. The software used for modeling is Solidworks with the CAM files generated in HSMworks. The CNC machine itself uses very simple ULN2003 drivers controlled with LinuxCNC.
Version 2 will use linear bearings to eliminate binding on the ends of the rods. The frame will also be cut with a laser, hopefully helping with alignment.
