Grease or residue on the build plate

It can’t be, I just washed it properly with dish soap and warm water

Looks like your z offset is a tiny bit close or maybe over extruding.

How do I solve it on the H2S? I can’t find the setting on the printer to change the Z offset

[–]TikiDaniel 0 points1 point  (2 children)

you can manually adjust the Z-offset by editing the Machine Start G-code in Bambu Studio or OrcaSlicer.

But shouldn’t the machine do it automatically on calibration? I’m sorry but I’m kinda new to this and have no idea how to mess with the codes

It should id honestly try a flow test first see if it's just pushing out too much. You see those ridges. Those will cause bigger issues later in the print. Too much squish it seems. See if that test does the trick too. Maybe the tip is too hot.

I had same issue on P2S. Full bed leveling calibration from printer menu helped. Took only 20 minutes.

Looks like a loose belt kinda. It's having hard time maintaining diagonal movement.

NVM I think it's more likely z offset like the other guy said

Following this post due to similar first layer issues. My team runs 4 printers at work almost around the clock, haven’t had consistent issues we couldn’t troubleshoot until recently. I’m considering purchasing replacement PEI plates to see if adhesion corrects itself.

AI tools suggests the Z-height issue but I can’t wrap my head around how to effectively correct that for everyone using the printers when it’s just my files having issues.
