Hi again Curtis,
I suppose I have to connect pc and RP388 with a null-modem cable? (asking because I hate to destroy things that I want to use)
As I am rather a 'hardware' type of man than a 'software' type, the simplest way for me is to be able to use (freeware) software that outputs g-code. I could make a controller that supports the g-code and can control the power pcb board, but then again I need the schematics of the power pcb and the sheets of the CMD-40 bridges I think. I can't write a translation tool from g-code to Cybervec, so I'm stuck at that part. If I find the time this evening I'll connect the rp388 to my pc and see what happens before I can take any further steps.
