So I can finally reliability print the PP filament I have.
Set up a filament profile turning off cooling for the first 6 layers, then max 50% fan speed, no auxiliary fan. Bed temperature at 100, chamber at 60. Seems to work well.
60mm/sec outer wall speed, 100 everything else.
Benchy came out decent enough. Some wispy hairs but not much else.
Super interesting filament to print with. I want to try combining into PLA as a "bushing" in a toy arm /shoulder joint among a few other ideas.
