Hello to everybody. I get the following error [Unknown command:“Z\_OFFSET\_APPLY\_ENDSTOP”] when Im trying to update z offset from fluidd interface save button. I have a delta kossel printer with manual probe system (microswitch) Any idea? [klippy.log](https://klipper.discourse.group/uploads/short-url/1VSkL4P0FXeitT3UlVPURHl9oJr.log) (354.1 KB) ---

Delta printers don’t have a z endstop, so this command will not work. ---

Ok, if this doesnt work how can I save a new z offset (in easy way) permanently? Now, every time I turn on the printer I have to remember to change z offset manually. And why does it show this button if it doesn’t work on delta printers? ---

The button is being shown by Fluidd. You would need to ask the those developers why it’s being shown. You can either add a gcode offset to your start gcode, or you can adjust the endstop positions of your A, B, and C motors. ---

Try this one: Z\_OFFSET\_APPLY\_PROBE [https://www.klipper3d.org/G-Codes.html#z\_offset\_apply\_probe](https://www.klipper3d.org/G-Codes.html#z_offset_apply_probe) ---

Thank you all, I think its a fluidd problem, jakep\_82 is right, I rose the topic in fluidd core team. ---

Fluidd fix it, but I still have the problem. While config file is ok now, klipper seems to ignore z adjustment in Z\_OFFSET\_APPLY\_PROBE. ---
