Ok I've nearly got to the stage where I can test my Y axis on my router.

The travel is approx 4ft with 2510 ballscrew (driven) My motors are the largest 34's from Zapp. I know a few of you have commented on the overkill of these and the problems with loss of torque with higher RPM etc, but I have the motors now and I might as well see if I can run with them.

I'm looking for cheapish drives for these motors. I've figured that my machine will more than likely run on nema 34's anyway, so even if I have to reduce the size of the motor they will probably running from the same sort of drive. I've looked at the 2MA2278 240V drives on ebay, but don't really know how good they will be? Has anyone had any experience with these drives or others that they could recommend please?

Thanks,

Adam.
