Klipper ignoring z offset any help greatly appreciated

Basic Information:

Flsun Super Racer
MCU / Printerboard: mks robin nano v3

for some reason its as if klipper either doesnt save the z height or something else is causing it to constantly run too close the bed or just barely above it. I am using a delta printer and after delta calibrate, probe calibrate, bed mesh level and then adjusting the z height on the first print to fine tune it. then it dials in really quick and prints a great first layer but by the second layer its running too tight again so i adjust the z up to fix the issue i get it dialed in again and by the next layer its back way to close to the bed again. Its as if it completely ignores the z height and goes where ever it wants i have had it print a wonderful print i save the z offset and restart_firmware to start another print and then it runs it so close to the bed that the filament cant print and starts missing filament. then i adjust the crap out of it like 0.300 or 0.500 and its good till the either the next layer or next print sometimes. I tried removing negaitive z offset of -1.5 after leveling and it wont print says move out of range as soon as i put it back it works again something is definately causing it to ignore z height adjustment if its dialed in and i save it on the next print its too close again like it has not merit of the z height all help is greatly appreciated below is my klippy log thanks

From your logs

probe: z_offset: 16.568
The SAVE_CONFIG command will update the printer config file
with the above and restart the printer.
save_config: set [probe] z_offset = 16.568
SAVE_CONFIG to '/home/pi/klipper_config/printer.cfg' (backup in '/home/pi/klipper_config/printer-20230205_101100.cfg')

and then after the restart:

[probe]
...
z_offset = 16.568

So apparently, saving your calibrated z_offset works.

Iā€™m not aware of any Klipper setting or issue that would provoke what you are describing. For me this sounds like:

  • a mechanical issue with your printer
  • improper delta calibration
