I bought a spool of Light Oak and one of Black Walnut. The X1C with AMS behaves oddly with both of these and is fine with PLA basic, matte, and metal. It looks like the printer is able to read the RFID tag because it comes up with the correct color in both cases. It then rotates the spool next to it and decides it doesn’t know what it is. Bambu Studio doesn’t deal with this well. I am using hand calibrated profiles with Orca and telling it that, yes I want to use that AMS slot.
The downside of making everything automatic is that when it doesn’t work correctly it can be a huge problem.
It is probably something simple like a bad batch of RFID tags. The printer knows there is something there but because it isn’t quite right the software gets confused. If you put in an override like it is a 3rd party filament, that goes away when the tag gets read again. I am sort of looking forward to running the spool out so I can safely open the spool and inspect the tags.
I had it work for a few hours once but the next day it was confused again.
I do quite like both flavors of the PLA-wood I have tried. I hope someone addresses this issue because it was quite annoying to have to run the calibration.
