Since 2.02.57 Bambu Studio was install, I have not been able to communicate correctly with my A1’s AMS lite with any new slices. It seems to always be looking for an external spool or uses the wrong spool. The existing sliced prints on my SD card work just fine. Only fix has been to roll back to 2.01.50. With 2.01.50, I can slice models and the AMS Lite works correctly again.
