On my original voron tap, I had z_offset set to zero.
With the Chaoticlab CNC Tap V2.0 I had bed adhesion issues until I ran PROBE_CALIBRATE in Klipper and discovered I needed a -0.385mm z_offset.
Intuitively, I would expect the nozzle to hit the bed, the tap sensor to activate, then that would be the zero offset.
Is this normal? How would I account for the negative offset value? Is that the distance the tap travels before triggering? Or does it have to do with latency between the sensor triggering and it being registered with Klipper?
