After testing the motors (un-mounted to the machine) they all jog correctly.
But, when they were mounted to the axis' on the machine, I would jog the axis then a few seconds later it would stop with a loud whining sound. Does this mean the motor has reached it's torque limit and stalled?
Since I only have a 4.5 amp power supply, I assigned only 1.2 amps per motor - thinking i need to share all the amps - is this correct? with 4 motors, can I set them all to 3 amps or do I need to share the 4.5 amp supply?
I did order a second power supply to run the two X axis motors.
Will more amps per motor give me more torque? I have 495oz steppers.
