Bambu Lab PA6-GF Profiles not available yet?

Another option is that you can use the printer bed to dry the filament. It’s not the most efficient setup but the moisture is expelled. If you have an X1C there is a built in “drying” routine you can run. If you have a P series you can set the bed temperature manually. Either case you need a filament box or printed cover to contain the heat around the filament to be dried.

I haven’t honestly printed much with PA6-GF but I have printed a decent amount with the newer ABS-GF and I haven’t had much issue with the .4 nozzle. If you clogging issues I would look at using the bigger size nozzle.
