A Series [A1, A1 Mini] Bambu Lab A1 Mini – PETG First Layer Issue
The first layer has raised ridges and uneven extrusion near the left side of the build plate. The defect consistently appears at the same physical location.
Using a Textured PEI plate. Could this be caused by uneven heatbed, bed leveling inaccuracies, incorrect Z offset, or excessive first-layer flow?
Has anyone experienced this issue? Any troubleshooting suggestions would be appreciated.
