Bambu Lab A1 Series Troubleshooting
1

Hi
From having a well-functioning A1. I have had a lot of different errors, it scratches the lithophane at layers 80-120, which I have been able to print before.
Another model that I have printed before looks like this, see movie.
Bambu Studio
printing time about 20-30 hours
I have run the calibration
Standard setting for general PLA
Filament from the spool
Latest firmware, uses the same PLA filament and degrees 220 67 same as when it worked.
I have cleaned the bed with dish soap and hot water.

What to do?

I can almost make out your fingerprint :wink:

You’ll need to take a clean, stiff brush, plenty of warm water, dishwashing liquid and thoroughly clean the plate. Maybe add a splash of Isoprop before and after.
Then try not to touch the print plate surface or use gloves or even just a folded paper towel to keep the fingers from the print area. Just like I tell my kids: Never leave any evidence :joy:
