MMU_CALIBRATE_BOWDEN BOWDEN_LENGTH depends on extruder_homing_endstop - working as intended? wiki update needed? #588

In some testing recently I found the following behavior:
If
extruder_homing_endstop: collision
, then during Bowden calibrationBOWDEN_LENGTH
needs to be shorter than the actual value (this is how the wiki describes it, measure the distance and subtract a bit from it). In this case it performs a fast move atBOWDEN_LENGTH
, then short moves until collision is detected. Calibration fails if collision occurs during the fastBOWDEN_LENGTH
move.If
extruder_homing_endstop: extruder
, thenBOWDEN_LENGTH
needs to be longer than the actual value. In this case it performs a single fast move until the extruder switch is triggered. Calibration fails if the switch is not triggered by the end of the fastBOWDEN_LENGTH
move. Following the wiki guide to subtract from the measured distance will result in calibration failure in this case.If the above behavior is the intended function, could the wiki be updated to advise either adding or subtracting from the measured distance, depending on
extruder_homing_endstop
setting?The text was updated successfully, but these errors were encountered:
