I need help understanding the Z offset system on the SV08.
Every time I initiate a print, it returns with an offset number roughly +0.900.
The printable offset is +/- 0.15mm, using PLA, which is causing me to have to calibrate for every print.
The machine restarts after Z calibration like it is storing the offset, but then on the consecutive print it is offset again.
I read some posts on reddit mentioning to change line 304 of macro.cfg to _CALIBRATION_ZOFFSET and made that change, but almost dug a ditch in the left edge of my bed plate.
Is this a mechanical offset of the inductive probe that needs to be corrected?
Some others on reddit suggested just adding the offset calibration to the macro for the filament.
I trust that is the expected behaviour but I am not sure. The only thing that I can tell is that :
I have exactly the same behaviour with z offset (and that working well for the first layer without manual adjustments even if the z change at restart)
I changed the configuration for the probe and that was a very big game changer for that you said (when the bed is cold, sometimes the print is cancelled before to print anything but I click to retry and it’s fine)
I ended up making the changes as outlined in one of gERGO’s YouTube videos. After this, and mesh calibration, the prints have started with a reasonable enough offset to print.
This includes changing the profiles in the slicer to allow heat soak at more appropriate temperatures.
