Beta 01.01.02.07 Issue Thread
I’m posting this thread for my self and anyone else that may find an issue that is either present in this beta or STILL present in the printer to share with everyone else.
First Issue I’ve found:
Nozzle clumping with PETG HF filament before start of print.
I just did a multi-color print with two different brands of PETG HF. The main color was on the right nozzle with Bambu Lab PETG HF Black (245c) and Generic PETG HS(220c) on the left. I actually just cleaned both nozzles while heated up before the start of the print as I noticed they both had a lot of build up on them and let them cool down while completely clean. After starting the print I noticed both nozzles heated up to full temperature for their profile before starting and during the nozzle offset calibration. This caused the nozzles to ooze before the tip gets to the sensor. The sensor then rubs the nozzle in circles and forces the filament that already started to ooze up the tip and all over the nozzle before the print even started. I’m not sure if this is new for this beta firmware but it doesn’t seem necessary for the nozzles to be at full temperature during the calibration. Maybe close, but not at full temp. I also notice with the H2D my nozzles are getting little balls of PETG HF in random spots on the print that I don’t get using the exact same Bambu Lab PETG HF that is fully dry with my A1M. This issue with the balling of filament is unique to my H2D and not the filament.
