MF70 CNC Working!
Posted by retromaster on December 1, 2009
I’ve finally managed to complete all the axes and get the CNC-converted Proxxon MF70 to work. The photo above shows the whole machine, and here is a video:
The USB control board is able to do linear and circular interpolation on board. I’ve made the host-side into a Python module, and coded a few scripts that enable me to move the axes using the keyboard or interpret Gerber or NC drill codes. It’s all in quite early stages, though. Shortly after I recorded the video above, the controller got stuck in one of the line segments and ruined the workpiece, so it seems I’ve still got some debugging to do. Nevertheless, it all seems to be on track, and I am already planning improvements to the machine, with parts to be manufactured using the machine itself.
