position_endstop in section 'stepper_z' must be between position_min and position_max

[Stevi84]

Hi all, i have another question ^^. my printer gives me an error message. After Z_ENDSTOP_CALIBRATE Klipper will restart. after i got the error message `position_endstop in section 'stepper_z' must be between position_min and position_max' . When i put it in the printer.cfg

position_min: -3
position_endstop: 0 -----> this entry here
position_max: 380

the error message is gone.
But when i restart the Z_ENDSTOP_CALIBRATE

Klipper is set a # before the entry

position_min: -3
#position_endstop: 0 -----> this entry here
position_max: 380

and the error message comes again O-o.
Can someone explain this behave?


Thank you

BR

The active position_endstop after you save_config is down the bottom of the file, in the save_config special block. From the error, I can infer that the value is slightly negative: fundamentally this is fine, it just means the endstop is slightly below the bed.

I assume this is a voron 2? If so, your position_min should be -5 as seen in all stock configs. This allows the endstop to work properly, as well as accommodating the fact that the gantry may well drop below "0" during the qgl process.

Yes it is a V2.4 with inductive probe.
