H2D I installed the 0.2s for some fine prints, and the device has malfunctioned in two ways: the printer no longer synchronizes the filaments. While Bambu Studio can still assign them correctly, if I touch them on the printer, they reset. In the menu I can only see the default filaments. Additionally, I had to disable nozzle clumping detection because it triggers unnecessarily.
At first I suspected the culprit was a wood filament I had left in one of the AMS units. studio did not like to sync the ams with that inside. I removed it and rebooted everything, but the problem persists. Has this happened to anyone else?
for the rest, print come good. (and cheap after tweaking the amount of material primed, defaults are a waste)
In the end I am just overriding all the stuff as usual, thank you 
Finally, the filaments are back in place and selectable. I reset the device, reconfigured it, and performed complete maintenance, including belt tensioning and full calibration. In the end, it was just a single duplicated filament profile (“PLA Bone”) for a 0.4mm nozzle. It was such old data that it only caused issues for the system after the latest updates. All in all, it didn’t take long, and I lost very little (just some basic PLA settings).
