Recently purchased 3 axis Promill, with non-working M-15 Centroid control. Looking to upgrade controller, without breaking the bank! Servos and drivers appear to be good, all 3 axis will jog. I spoke to a "guru" who says he can rig a PC to my drivers, if I can come up with operating software. Anyone have any suggestions? I'm just a tired old working man, trying to set up a small shop at home, to suppliment an upcoming retirement, with limited resources.
