Comment on I'm Unable to get any PETG HF Filament to Stick on the Bed after having Switched from a 0.4mm to a 0.2mm Nozzle [Bambu P1S]

A quick and dirty thing to try is to increase your first layer height, .1mm layer is a pretty fine layer line. Bumping the height up can give you a bit more contact area and increase adhesion some. And slow down. The default settings are NOT gospel and the HF doesn’t mean you can or should print that fast. I find when using such fine nozzles I often need to reduce feed rates by 30 to 40% to get things to hold. And I even drop the acceleration rates by 10 to 15% to keep corners from not sticking well.

Speed ain’t everything.
