RRF 3.0 + Bed Heating issue
-
Board: Duet2Wifi:
After migrating to RRF3.0 - I am getting a heating error every time I try to heat up the bed.Error: Heating fault on heater 0, temperature rising much more slowly than the expected 1.8°C/sec
While this certainly is a nice thermal runaway feature. The tolerance seem a bit off, for a bed.
I am sure I have misconfigured something.Any ideas?

M572 D0 S0.45 ; Pressure advance causes the extruder drive position to be advanced or retarded during printing moves by an additional amount (0.8% of tube (56cm) = 0.448 proportional to the rate of extrusion. At the end of a move when the extrusion rate is decreasing, this may result in the extruder drive moving backwards (i.e. retracting). Therefore, if you enable this feature, you may need to reduce the amount of retraction you use in your slicing program to avoid over-retraction.; Miscellaneous

That error should go away if you tune the bed heater using M303.
