My Z offset is consistently too high by about **0.1 mm** on every first layer. No matter how many times I calibrate, the nozzle always sits just a bit above where it should be. **Troubleshooting so far:** - Verified with `GET_POSITION` that no hidden gcode offset was active. Console showed `gcode base Z: 0.000`. - Ran `PROBE_CALIBRATE` + `SAVE_CONFIG` multiple times the value updates, but the nozzle still ends up 0.1 mm too high. - Looked at `[z_offset_calibration]` with `internal_endstop_offset: -0.25` → tested with it set to `0`. No effect on the 0.1 mm error. - Noticed that the main probe config had `#z_offset` commented out, so the actual active value was coming from the auto-generated **SAVE\_CONFIG** block at the bottom of the file. - Tried hardcoding the `z_offset` in the probe section and deleted the **probe z\_offset** part of the `SAVE_CONFIG` block while keeping input shaper and other auto-saved settings intact. I’m totally lost and have no idea what else to do. I’ve had this issue since day one of getting the printer. I haven’t changed any of the default settings ---

You can hardcode Z offset in filament profile like this, btw I have the same issue. ![image](https://canada1.discourse-cdn.com/flex030/uploads/sovolforum/original/2X/e/e47662b873e1a9d2945e99343e628ee5221f06c7.png) ---

Thanks! Glad I’m not alone. Hopefully, Sovol will patch a permanent fix! I have never encountered this issue with my other Klipper printers. I’ll keep digging. ---

I’m having the same issue, I think it’s to do with the printer using the same point twice to calibrate the Z offset, and the second time there is a tiny blob on the plate at that position. ---

I did some testing today and changed the internal\_endstop\_offset to -0.10 (in the printer.cfg file under [z\_offset\_calibration]) instead of the -0.25 that was there by default, and it seems like it worked! ---

> [@maker](#): > > internal\_endstop\_offset Isn’t that backwards? `internal_endstop_offset` doesn’t seem to be a standard Klipper setting, but usually to lower by 0.1 you would change a setting like that to `-0.35`, right? ---

So for anyone else, the way I am handling this is similar to the filament change, but for the whole machine profile. Under the Printer settings, and `Machine G-code` tab, I added this to the end of `Machine start G-code`: `; Added to lower Z by 0.1` `G90 ; Absolute` `G21 ; Use metric` `M83 ; Use relative distances for extrusion` `SET_GCODE_OFFSET Z=-0.1 MOVE=0` I added the extra items above the offset change since they were always included in generated GCODE first. I’m guessing `G21` is the only one that matters, but better safe than sorry. ---
