Hi,
I recently upgraded prusaslicer to 2.6 ( probably not related but I prefer leaving all information).
I'm printing litophanes with Overture professionnal white filament.
On my latest lithophane, At a random location ( begining of the print between 0 to 2h of print) I have a message to change the filament. once removed and put back, after a few minutes: same message.
there is no jamming, filament is going out nicely at change.
First time I have this trouble, only thing that has been changed is prusaslicer.
note : I checked the Gcode: no trace of M600 gcode
