For the M552 just use M552 S1
For the heater heating too slowly error that's different. You must PID tune the heaters.

Heaters are tuned and work just fine again. Joy!
Now unless there are other things I might need to do, I have to go back and redo the calibration since the first layer of my test print is too close to the bed.
