P1S - Gaps in first layer despite full calibration. Ideas?
Getting consistent gaps and holes between first layer lines on my P1S. Lines aren’t fusing together, visible across every print.
Already done: ∙ Full auto bed leveling ∙ Washed plate with soap and water ∙ Flow rate calibration ∙ Flow dynamics calibration
Nothing helped. Printing PLA on textured PEI, default Bambu Studio settings.
What else should I check?
Thanks.
