I’ve been going around and around with my P1S and cannot get the AMS to change filament types and colors to match what I have in the setup in the ‘Prepare’ tab of the slicer. I’ve tried everything that has been discussed in this thread short of deleting and reinstalling the software as mentioned. Occaisionaly the AMS will randomoly get it correct when I changout filaments but sometimes it doesn’t like tonight. However, after messing around with things for a couple of hours I tried the Handy app. Change the filament type and color through the App and it went right through correctly in the Device tab as well as the Prepare tab in Studio. Go figure.
