fsensor_stop_and_save_print

The printer hasn't had any modifications made to it for a long time.  However today, it has started giving this error, multiple times.

I'm using Octoprint to drive the printer, and looking in the console I'm getting :

I remove the filament, trim the end (to remove the blob / but an angle on it), replace it, and away it goes again.   It might go 20 seconds, it might go 10 minutes, then it happens again.

Looking at the gcode in the Prusa Gcode viewer, there is nothing there telling it to change filament, which leads me to think that it is a printer rather than gcode problem.

Any suggestions on where to look next ?

TIA
