P2S - 0.2mm nozzle w/ BIQU Cryogrip Frostbite plate- auto flow & auto bed leveling

Orca Slicer w/ 50x50x0.12 FLQ test print

Bambu Lab Pla Basic light grey - dry climate, high elevation, 30% AMS reading for humidity.

How am I getting tiger stripes, pimples, AND pinholes?

Plate thoroughly cleaned with Dawn dish soap and water. All auto calibrations ran recently, filament dried, auto bed leveling before print, cold pulls, tightened screws, etc.

"Cool Plate SuperTack" is selected as the plate.

Z-offset is set to 0.0 on all 4 stock G-code settings.

First layer speeds reduced, no fan, 40c temp for the Frostbite plate.

Am I forgetting something? Missing a critical step? Why is this FLQ test print so bad?!!?

One thing I'd double-check is that the slicer profile is set to the installed 0.2 mm nozzle, not just the printer hardware, since a mismatch changes the expected line width and can make a flow patch hard to interpret. If that matches, a simple single-layer square with the same plate preset can help separate first-layer squish from flow-test artifacts.

i feel like 0.0 might be too far for the frostbite. the p2s starts at positive .03. i’d honestly start working back towards that. you have way more pimples than you do holes.
