Klippain branch

  • I confirm using the main branch //was on dev branch but the macros in question look to be the same version

Version

v4.3.1-39-g3d60c20d

Describe the bug and expected behavior

My print ended on a move out of range error:
Move out of range: 208.744 156.325 300.020 [265542.968]

My Z max at the time was 300 and the print's height was 241.800 so my guess is the park in the END_PRINT somehow messed up the the calculation of max_z. The macro correctly takes the z offset into account, but when I apply a bed mesh, I can reproduce the error with the following g-code sequence.

G28
BED_MESH_PROFILE LOAD="default"
G90 
G1 Z270 F1500
PARK

It seems the bed mesh corrections or some kind of side effect there of are not taken into account when calculating the save z height. I have not been able to figure out where exactly the offset is coming from, maybe a result of the fade out of my mesh, and added a 1mm safety margin via overrides.
