I'd be happy to send out my code when it's more or less working, but
it's not quite there yet, and I imagine could use alot of improvement.
I didn't mean to bang on EMC, I just didn't remember it having a
CAD/CAM app. There was an openGL gcode dry-run previewer which I
thought was pretty good. The control I've got is a dedicated DOS
machine with a 100MHz Pentium and an interface card that does things
like control coolant and tool changes. I spent alot of time five years
ago tearing out the PDP-11 (!) and it's three wirewrapped analog/digital
interface boards (!@#$#) in that machine and adapting it for PC
controls. Nowadays, for a machine like mine, limited by its stepper
resolution and maximum feedrates, EMC would probably perform as well.
I think my only concern about EMC was its output pulse timing and
maximum step rate, which seemed inadequate to take advantage of modern
microstepping motor drivers. Since those drivers run about 500 to 1000
bucks a pop, minus power supply and everything else, they're sort of
out of the enthusiast range anyway. Maybe it would be fun to build one...
