I have a problem in our Brother HS-50A wire EDM machine.

X and Y axes stop for an alarm. When moved manually, axis stops easily for this error when gripping the lead screw by hand. It's seems that motors have rather low force. Power supply of servo cards shows 24 VDC and no drop seen. I have also swapped the XY servo card from working machine, but problem persists. We had similar problem earlier in Z-axis, and we found that motor brushes were jammed, but we cannot find any problem from other motors.

Any idea what's wrong in our machine.
