Klipper keeps deleting my Z offset instead of saving it (lemmings.world)

Every time I use calibrate_probe, I get the message "The SAVE_CONFIG command will update the printer config file with the above and restart the printer."

When I click Save Config, it restarts the firmware, and then I get the warning "Option 'z_offset' in section 'bltouch' must be specified."

If I go check my printer.cfg, the [bltouch] section now has z_offset commented out with the old value and I have to remove the comment and copy in the new value.

Am I missing something? What am I doing wrong?

You need to comment out your z_offset from yourbltouch config. It should look like this:

and your printer.cfg (System added values etc) should look like this:

If I do that, I get an error saying that my bltouch needs a z_offset, and it won't let me do anything until I un-comment it.

Any possibility that you've accidentally modified something in the automatically generated part of the config, so its failing to read the saved value? Perhaps you could attach your entire printer.cfg?

Please share the auto-generated part of your printer.cfg so we can help you.

Had the same issue. Try Z_OFFSET_APPLY_PROBE before SAVE_CONFIG.

If that doesnt help, try Z_OFFSET_APPLY_ENDSTOP instead.
