[BUG] Incorrect home z
trafficstars
How to observe the problem:
- configure probe offset perfectly (*)
- place some sheet on the bed
- home z
- thanks to the touch sensor the 0 is now the surface of the sheet
- move z down until the nozzle has light contact with the sheet => if the value is 0.2mm, this is the home z calibration error
(*) probe offset:
- sheet on the bed under the center sensing position
- BL OFF
- run probe offset
- adjust until the nozzle has light contact with the sheet, this offset is the difference between the sensor and the nozzle.
Hypothesis:
- may be 0.1mm offset is added at probe offset time?
- may be z homing is done in the wrong way relative to the BL correction? (sensor is placed in the middle, but this is not the nozzle position)
- may be the mesh does not consider the offset between nozzle position and sensor position?
- any other idea?
