More of an observation/annoyance than a problem but…
It appears that I am unable to select TPU on the printer for printing from an external reel. I can set it in Bambu Slicer and the Handy app but not directly on the printer.
I have checked in Bambu slicer that I have check marks against TPU in my filament list.
Firmware 1.8
Interesting. Somehow, unfortunately, I don’t remember exactly how, I set the external roll to TPU and the machine remembers it.
You can set it anywhere other than on the printer and the printer will remember it.
I have the same problem. Does that mean that I have to manualy load the TPU into the right extruder and then select the TPU in BamubStudio and print?
Set the extruder to your type of TPU using Bambu Studio or Bambu Handy before you load the filament into the printer so it uses the correct temps.
