Problem with power to the motors and/or feedback from the encoder on the motor.
If SV_STALL error is displayed, it is almost always caused by a previous error – such as full
power without motion, position error, encoder error, drive fault etc.

If you are getting
position errors
, disable stall detection in the PID menu of CNC11
and try moving again. Does the motor move as expected? Do you need to reverse the
direction of the axis?

Quadrature Errors are either a problem with the encoder shield, grounds, or faulty
wiring.
For other errors, please see the Operator's Manual.
