Load new filament into AMS while printing

Bambu Lab H2 Series Bambu Lab H2C
1

I have 3 rolls of the same filament. 1 has very little left, the second has about a third of a roll, and the last one is brand new.

I want to print something that takes most of a roll so I wanted to use up my partial roll first before using the brand new one.

My plan was:

  1. I load the first roll in the AMS and the second roll in the external spool.
  2. Start the print.
  3. Wait until the first roll (in the AMS) is used up and the printer switches to the external roll.
  4. Load the full roll in the AMS.
  5. Let the printer switches back to the AMS when the external roll is done.

Two questions about that plan:

  1. Does the H2C support switching between the two nozzles when auto back up is enabled?
  2. Can I load new filament into the AMS while the printer is printing.

I don’t want to load all rolls before starting the print because I don’t want the printer to start using the new roll before the other two.
