[Solved] BambuLab X1C AMS Automatically switch slots when filament is out

If your Bambu Lab X1C printer stops and waits for a refill when a spool runs out instead of switching the AMS to use an equivalent filament, do the following:

  • Check that the spools have the exact same parameters in the Bambulab printer, including color and temperature characteristics.
  • Make sure the printer is not using firmware Version 01.08.02.00.
  • Verify that the equivalent spools show up as backups for each other in a sort of circular icon showing the equivalent spools in the slicer print screen.
