Hi,
Can anyone tell me what voltage should be going to the motor on each pair of lines.
This problem is on A axis RT with no load power 360 + & 360 - works well, under load -360 loses steps.
Tried swaping axis same results loses steps one way.

Just tested out at the motor connection first pair read 3.9 to 4 volts, second pair read 5.8 to 6 volts same readings whether clock wise or anti clock.

Anyone come across this before.

regards

Phill
