You need to enable logging and check what happens to trigger it. Possible reasons: - filament end detected - serious error from firmware - firmware requested pause - user hit pause - Printer connection got lost (undervoltage of pi, EMF( and you have not selected to continue print after quick reconnect or reconnect triggers reset preventing continue.
In any case you should see some hint in print log about the reason or in console if it was active when it happened.
