Well I've just about got this thing going, but now I have an error with the spindle. I believe the machine is fine, but the regenerative braking on the spindle motor may be too much for my phase converter. I need to figure out if I can some how add bleeder resistors, or capacitors to take up this energy. Only other option is to purchase a larger phase converter, but that is a big cost to incur, especially if it ends up being a fault with the machine after all.

Any ideas?
