Purge Nozzle and Dry Filament to Eliminate Moisture Pressure

1. Remove the current PETG filament from the printer. 2. Dry the spool at 65°C–70°C for 6–8 hours in a dedicated filament dryer. 3. While the filament dries, perform a cold pull on the P1 nozzle to clear any residual debris that may be trapping moisture-laden material. 4. Reload the dried filament and initiate a test print; successful moisture removal is confirmed if the printer no longer exhibits pressurized oozing during non-extruding travel moves.
