Thermal Runaway, Heater_ID: bed
Thermal Runaway, system stopped! Heater_ID: bed - Printer halted. kill() called!
after this issue occurred, i rest the printer and set to pre heat bet to 60C after 20 minutes there was a time where the bed temp gradually dropped off to 56C for less than 1 minute then returned to 60C for 50 minutes then temp dropped again to 54 and had error "occurred"
my logic: if it were a thermister issue it would not show a gradual decrease and then a gradual increase to back set point and i would expect to see more erratic temperature readings.
i am trying to get a digital thermometer to monitor bed temp, or should i just replace the bed?
