Need Suggestions on what hardware we need to convert an Older Thermwood c50 to Mach3. The CNC has Big MHO ( Baldor Servos) and West Amp Drivers # 33026-5. What Interface Boards will work with this config ?? Would we be better off changing out the Old Servos and Drives to new? We had a 5' X 10' Omnitech with Fanuc PC Front-end, but had to sell last Fall. So we are taking this Heavy Duty Router and trying to interface with Mach3. Any help would great !!
