OrcaSlicer Version

2.3.1-beta
2.3.1-alpha
(and some nightly inbetween alpha and beta. Did not try older versions.)

Operating System (OS)

Windows 10 22H2 10.0.19045

Printer

Bambu X1C

How to reproduce

Load model
Set model to external non-AMS filament (Slot 5)
Press Slice Plate
Press Print Plate
Deselect "Enable AMS" as usual
Press Send

Actual results

X1C on firmware v01.08.02.00: Printer prints, no issues

X1C on firmware v01.10.00.00:

Printer gets to the stage where it heats the nozzle to printing temperature
Nothing happens anymore
After about 12-14mins Orca displays an error: Failed to get AMS mapping table; please select "Resume" to retry. [07FF 8012 181114]

Expected results

Printer prints with external filament on firmware v01.10.00.00, no issues.

Project file & Debug log uploads

orca_debug.zip

Anything else?

This problem still occurs after a complete factory reset of the printer.
The printer is in LAN-Only/Dev mode.

I am guessing here that this may be related to changes in how the Bambu firmware handles external filament mapping?
Their Bambu Studio does not have the option to enable or disable the AMS anymore when sending a print, instead the user has to select the mapping as external in the AMS/filament dropdown. See Screenshots for Details.
