How to best set z offset for higher temps than the built in macros

Sovol SV08
1

I print at higher temps and want to set my z offset at these temps but the built in macros always fo ce me to 65c for the bed and something lower for the nozzle as well. I print at 85c and 270 nozzle and would like to calibrate the z offset for this thermal variance.

How to best achieve this? Or how I can I easily adjust the already calibrated z offset from the lower temps when I print at these higher temps?

The Z axis on your printer is how far the nozzle is above the bed.

Changing the Z offset won’t change the temperatures at all.

Klipper does have a temperature offset but it is intended to correct for inaccurate sensors.

Print temperatures are (usually) handled in the slicer software.

Are you trying to change the preheat settings? They are typically handled by the User Interface, Mainsail, Fluidd, Klipperscreen, and Sovol’s built in interface each have their own settings.

I want to calibrate the z offset when the bed and nozzle are at printing temps. For me, the printing temps built in to the macros and gcode are not high enough for me. When the bed and nozzle are at higher temps they will expand etc.. giving a more accurate offset at those temps

Open macro.cfg in Mainsail or Fluidd. Find the section below.

Note: _CALIBRATION_ZOFFSET calls CLEAN_NOZZLE and relies on the temperature that is set in it.

Change the temperatures however you want. If you are not familiar with the g-codes for temperature (M104, M109, M140, M190) see here
