start_print doesnt seem to be working

[WaskaLabs]

Have tried with a few varieties of function calls to attempt to get this working.

printer.start_print with:

("FILE.gcode", 1)
("FILE", 1)
("FILE.3mf", 1)

... and various less likely to work just to test. Cant seem to get it working on this API or others found on GitHub. Possible patch from Bambu?

Using P1S

Connection and light control work fine, Printer status: UNKNOWN

Haven't tested this in a while but from what I remember start_print requires the file to already be available on the printer. Try the upload_file to upload your sliced 3mf file and then the start print command with the filename with ".3mf" extension.
