To check your filament.
Home the head. Lower the plate. Load filament at intended print temperature. Move the head to the front, Tap the extrude button multiple times. Support the extruded filament so it comes out straight and so it doesn’t stretch from its own weight.
If the filament is really wet you will hear it popping and possibly see puffs of steam coming out the nozzle.
Run the extruded filament between your fingers. It should be perfectly smooth. If it is damp you will feel rough bits and pock marks and that is how it will print.
