I printed a model in PETG shortly after a PLA print, which was fine, and it damaged the plate as shown. What’s odd is I’ve printed this same model with this same filament on this printer and it was fine. The temps in the gcode are the same between those prints.

Is this a Z-offset issue? Would PLA and PETG require different Z-offsets on the same printer?

Edit for more details: Creality Ender 3 V3 SE, stock plate.

    Thanks for this! Yes, I do know they aren’t necessary related. However, I had no problems with the Z-offset on my machine until I did auto bed leveling. And subsequent leveling have also left the nozzle too high for proper adhesion (at least with PLA). So they are related in terms of my process of adjustment, whereby I have to adjust Z-offset after a bed level.

    For the first few months I’ve had the machine, it’s moved around my shop a bit so I have been running bed leveling more frequently than perhaps normal, since I assumed movement is bad for leveling. Now I think I have it somewhere semi-permanent it should be less of an issue going forward.

    I can also adjust Z-offset on-the-fly, which I usually do during a specific bed leveling test print.
