X2 Mill motor Problem

[A11an]

I've had the brushes out and they look fine.

It seems like whatever measures the load is faulty?

I would of thought that it's more likely to be the controller, as that was a known weak point on the lower power machines.

I'd recommend searching/posting in the benchtop machine forum over on CNC zone (Benchtop Machines) as the X2 is quite popular over there, and most problems have been discussed at some point.

These otors and controllers are used in the small lathes as well. CNCZone seams to be awash with people having problems with the controllers. They all seem to upgrade in the end?

The general concensus seems to be to upgrade to a KB DC controller (KBIC is the bottom of the range and will most likely do everything you'll need it to)

KB website is Variable Speed DC Drives and DC Motor Speed Control, and Axis Controls is a UK supplier who I've used in the past(KBIC DC Speed Controllers)
