Bambu Lab A1

How to reproduce

I have an A1 printer, synced with the AMS. I select the colors for my model in the slicer using the colors from the AMS. Then when I want to print, the preview shows up prompting to select the colors in the AMS to correspond to the colors selected in the slicer. They are automatically selected to be the right ones.

Actual results

The 3D preview of the print shows the right colors for a spit second, then permutes the colors. The print print normally, and not with the colors shown in the end in the preview. The preview on my printer shows the correct colors.

Expected results

The right colors should be showing.

I am also seeing this! Even on projects that have a single colour, it somehow still shows the wrong colour in the preview box

Same here with my X1C. OrcaSlicer 2.1.1 The Preview shows X+1 color. Choosen color 2, preview 3 or choosen color 1, preview show 2

Duplicated of #5765 #6203?

Same. Been doing this for quite awhile now. In addition, Orca selects the wrong AMS slot when you don't have spools in every slot, and you select a slot after one that is empty. For example, If I have spools in slots 1, 3, and 4, and I set the model to print from the filament in slot 3, Orca selects AMS slot 1, at least that's what shows in preview. The only fix is to remove the filament in the first slot, or move the one in slot 3 to slot 2, and re-slice.
