Printer

Bambu X1 and any P1P p1s

How to reproduce

I have 5 p1p and 2 p1s and an X1 Carbon. After I upgraded from 1.8.4 to 1.9 I am no longer able to sync ANY AMS to bambu studio. I have tried everything from reinstalling BAMBU Slicer to restarting the printers and the computer. I then attempted to downgrade to 1.8.4 and everything instantly synced and worked again with no issues no matter how many times I resync. Then I upgraded to 1.9.3 again and the problem was immediate. I was forced to revert back to 1.8.4

Actual results

I have 5 p1p and 2 p1s and an X1 Carbon. After I upgraded from 1.8.4 to 1.9 I am no longer able to sync ANY AMS to bambu studio. I have tried everything from reinstalling BAMBU Slicer to restarting the printers and the computer. I then attempted to downgrade to 1.8.4 and everything instantly synced and worked again with no issues no matter how many times I resync. Then I upgraded to 1.9.3 again and the problem was immediate. I was forced to revert back to 1.8.4

Expected results

All AMS units SHOULD sync like they did in 1.8.4 If I try to use just the sync button I get "no compatible filaments found, even though I have 4 rolls of your own filament with the RFID. I have 4 AMS units connected to the X1 and just one on the other printers however the results are the same. Conclusion it is a bug in BS above 1.8.4 as this version works flawlessly.

May I ask if you have enabled multi_machine? If you have enabled group control, it may affect synchronization and cause issues for you.
