Bambu A1 Abs Problem

Bambu Lab A1 Series Troubleshooting
1

Hi,
I’m currently using Bambu Studio with a Bambu Lab A1 printer. While the slicer successfully slices models using materials like ABS, ASA, and PETG, the printer doesn’t allow me to start the print.

This issue didn’t exist before — I used to be able to print with these materials without any problems.
I’m using a 0.4 mm nozzle and a textured PEI plate.

Could you please help me identify the reason behind this?
I would really appreciate your guidance.

Is your A1 inside an enclosure? ASA and ABS need high chamber temperatures to print and also very high nozzle temperatures.

I was able to reach high nozzle temperatures before without any issues, so that’s not the problem. I’ve only been experiencing this issue for the past week. Also, my printer isn’t enclosed in any case — but it wasn’t enclosed during previous successful prints either, so I’m quite surprised by this situation.
