I’m having the strangest issue with Bambu Handy. A few weeks ago I printed with TPU on one of my X1Cs. I used a top mounted spool holder and configured the filament as the external spool. Everything printed just fine and all was well in the world.
I have switched back to PLA in the AMS and cleared out the filament config for the external spool. If I am printing from Bambu Studio on my Mac, everything works as expected.
However, I cannot start a print from Bambu Handy for that printer anymore. No matter what I have the filament settings set for I continually get the “TPU is not supported by the AMS”.
Nowhere does it show that I am trying to print with TPU.
I have rebooted the printer multiple times, logged out of Handy and back in again and even reinstalled the app on my device. I’m not sure what needs to be done to get Handy to stop thinking I am trying to print with TPU.
