I am printing a 3 color print and the whole first layer is white but the printer started out with red for the prime lines then changed color to blue for the brim and part of the purge tower then changed to white for the first layer of the print ? it did exactly as the sliced preview but I couldn’t find anyway to change it I just don’t know why the first two filament changes for no reason when it could have just loaded first layer color for the prime lines and first layer of purge tower.
Submit an issue on github for bambu studio. That is a terrible way for the slicer to behave.
