Re: Multicam MG Series 304 - conversion to run with Mach3?
Pull a motor off and compare the mounting dimensions to a standard NEMA 34 stepper. A 750W servo motor would replace those. On the other hand, if the existing motors and drives are working, you can replace the controller and leave the motors.
Rather than Mach3, take a look at Centroid products. The Centroid Acorn would be a perfect fit. As far as motor replacement ClearPath or DMM Tech servos would be my choice for replacements. I have used both with good results. For maximum performance the DMM Tech servos would be the better choice and are a bit less cost than the ClearPath. But the ClearPath is a bit easier to install with less parts.
