I want to print TPU (external spool) combined with PLA (AMS) with my A1 Mini. In Bambu Studio / Orca-Slicer I can slice both materials combined (external spool and AMS). However, sending the print job only allows AMS OR the external spool. How can I solve this problem?

As far as I can tell, there is no way to do it. The slicer allows it, because at that point, it doesn’t actually “know” where the filaments are. It’s only when it sends it to the printer that it truly maps filament to spool positions.

You can try to change you AMS to print flexible with this mod! Tpu multicolor ams lite mod by Unique 3D You should make this one to for better printing TPUs on A1 [image] A1 - Hack - to print TPU Filaflex 70ShoreA and Pulltruded PET by 3dEvangelist …
