Printing PETG-CF Or ABS-GF Or Any Other Fiber Containing Material on the Bambu Labs H2C Using a 0.4mm Nozzle

Support :SUPPORT:

I am making this post for future humans who search "Can I print PETG-CF or ABS-GF on a Bambu Labs H2C 0.4mm Nozzle". The short answer is yes. The long answer is that I have 3 failed prints due to clogged nozzles after ~1kg of fiber filament through the nozzle. If you want to print fiber filaments through a 0.4mm nozzle, you will need to switch nozzles after <1kg of filament, or perform multiple cold pulls after each instance of printing fiber filaments.
