yes, disable steppers
then hand raise the nozzle using the lead screws,
measuring that its even on both sides, and paper thickness away from the bed
then raise the end-stop so it just clicks, or it may light up if you are using a mech V1.2 end-stop.
then on your software, home Z axis and it will rise, and it will lower to the end-stop location,
measure with paper again and make sure it is even on BOTH sides.
if it is uneven on the opposite side to the end-stop, disable steppers, or unplug the stepper, than lower just that side until at the right height, then plug back in
home Z-axis again and measure.
