As I started a new print this morning the display changed, it was showing EXT 200/200 bed 60/60, it now shows ext def/200 bed def/60, I've tried the usual switch on switch off and reloading the file, any ideas ?
Prontorface shows
extruder temperature sensor defect
heated bed working
I swapped both thermistors and reset the printer, same display messages and prontorface message
