Have had A1 for 5 plus years but resiliently i can not run 3mf files from Bambu Studio. If I change to stl or 3mf Basic it will run. All the files on Bambu Studio will change to Another Printer type Like A1 minny or P1s and when I change back to A1 and slice it Shows Twice the run time and if I try to run it runs very slow and goes through a odd start procedure.
