Mr WheresWaldo, If I remember correctly you have or had a Creator Pro? Today, what ever I set the heatbed to, it is always defaulting to 120. Even if I set the heatbed to 0 in Simplify3d. I turned the preheat settings to 0 and turned the bed off in preheat. I even tried older prints that I've successfully printed in the past and it still defaults to 120 during preheat.
