Thanks for bringing this to our attention but this doesn't seem to be a reproducible problem.

We may be missing something but this may sound like an unfortunate coincidence as our developers couldn't reproduce and study the problem, so please make sure to thoroughly double-check this case with the help of our Customer Support. https://help.prusa3d.com/article/customer-support_2287

Chances are that the filament sensor settings have been unintentionally modified, or the filament sensor mechanism is slightly dirty, misplaced, or deformed.

Hi thanks for the reply, to note you did use the non mmu profile on prusa slicer so as not to enable the purge tower, i belive this is where the error lies. I can reproduce this so it is not a coincidence and everything is fully stock fillament sensors work fine. no loading issues and printer report correct state at all times. would you like me to upload a 3mf of how i mean? also to note you were using conenct to print from? many thanks
