Bambu A1 with Bambu .2 nozzle printing Bambu PLA Tough on textured PEI plate.
About to loose my mind:
Issue:
Purge/test line at front of plate sticks properly.
Actual print first layer starts okay, then becomes extremely squished/smeared and develops drag marks/gouging by the nozzle.
- On larger models especially, layer 2 starts dragging across the print.
- Some areas form troughs with raised white edges, almost like the nozzle is plowing through the filament.
Current settings:
Initial layer height originally: 0.10
Initial layer width originally: 0.25
Outer wall speed reduced from 120 mm/s to 35 mm/s
Max volumetric flow already conservative at 2 mm³/s
Bed temp tested at 65 and 70
.2 nozzle profile correctly selected
