QSP2 servo amp | 19 December, 2014

My QSP2 motors keep shutting off with an error message on the screen that says Z1 motion fail. Z safe motion motion failed due to previous error. When homing the heads I observe the servo amp indicator LEDs. They are all green while the gantries are homing, but when head 1 drops down to calibrate the quadalign, the Z1 servo amp indicator turns from green to amber, then they all turn amber, then the motors shut off with the error meessage above.

Is it ok to swap the Z1 and Z2 amps to see if the problem follows? or should I switch the power supplies?

Swap the amps but first manually check by hand to make sure the z-axis is free to move up and down. Sometimes a part can get stuck in the gears.

Good Luck
