After installing updated firmware when it finishes the cut and raises up it squeals for a couple of seconds. It does not do it hen raising with the knob on the control panel.
What could be wrong
@Finney
Double check your Max acceleration settings for you Z axis
Go to Settings-> Machine Settings-> Max Acceleration
It should be 30
However in some cases the machines left the factory at 60 by mistake. So in situations where the head has to move a long way up it will sometimes over shoot the max speed of the motor.
This is not related to the update it’s probably just a coincidence
