Can you post the results of M122 and M98 P"config.g"? Please verify that your motor phases are wired correctly. https://duet3d.dozuki.com/Wiki/Choosing_and_connecting_stepper_motors#Section_Identifying_the_stepper_motor_phases Once you have the phases correctly identified if you're still getting the error message they the motor on a different driver to see if the error follows the motors. similarly, try a motor that worked on another driver and try it on the X/Y to see if the error is still present. This will help us determine if it's a driver problem.

Reduce the PWM of the heater. This way the heater will heat up slower along the heat to soak into the build platform at a more constant over all temperature. I believe that you can set the PWM on the heater tuning.
