Re: [CAD_CAM_EDM_DRO] Maybe OT, reprap build started

Glad to hear that. So can you share some URLs? I'm not talking about
drawings for bits of plastic, but about PCB schematics and microprocessor
source code for things like temperature controllers. Also I'm wondering how
to calibrate the extrusion speed to the head motion speed. Has anyone made
up some tables correlating filament size with temperature and extrusion
speed and nozzle size and head travel speed? That's where the important
knowledge is if you don't want to re-invent the wheel. Moving things in
X-Y-Z is the easy part.
