      Now I'm stuck with error at bed heating.
      Error: Heater 0 fault: temperature rising much more slowly than the expected 1.7°C/sec
      Duet 2 Wifi power a solid state relay for a 220v heater.

      I executed M307 H0 S90
      M307 H0 results in below.
      Heater 0 model: gain 340.0, time constant 140.0, dead time 5.5, max PWM 1.00, calibration voltage 0.0, mode bang-bang

      Then I tried to save the value
      M307 H0 A340 C140 D5.5 V0 B0
      But it result in
      Warning: M307: Heater 0 appears to be over-powered. If left on at full power, its temperature is predicted to reach 365C

        That's expected. The warning is letting you know what the max uncontrolled temp could be.

          @Phaedrux Ok, but I still not able to heat the bed. It start heating but halt after few seconds. Error: Heater 0 fault: temperature rising much more slowly than the expected 1.7°C/sec

            Are you sure you saved the PID tuning results with M500? Do you also have an M501 at the end of config.g to load the saved results?

                In config.g change M307 H0 B1 S1.00 to B0

                Then delete your config-override.g and run M307 H0 S90 again after a reboot. Then save with M500.

                  Also make sure you're starting from a cold bed state.

                    Update:
                    My bad, it might be M303 H0 S90
