Hi @mineau23
of course you should make sure, that your bit doesn’t move up. If this is guaranteed, I recommend:
- change your Driver from DRV8825 to TMC2209 V3 (see here: Solving Z axis lifting problems, stepper losses)
You can change only the driver of z-axis, Vref should be at 1.1V and you need to change the step-config in Estlcam.
That makes a huge difference!
