      Heater fault at startup

      I need to place a 100 msec delay between M307 and M143 in order to avoid a heater fault on heater 0 at startup.

      I conclude there must be some delay between setting up heaters parameters and the setting up the limit temps.

      Am I right?

      Many thanks

        @audryhome I've never heard of a delay being needed before. Which firmware version are you using, and what type of temperature sensor?

          @dc42 Heater fault happens at power on only.
          So far, my best remedy is to put a 30 Sec delay at the end of config.g and this cures the symptom.
          Will investigate further. Possibly a config mismatch or a wiring problem, but since bed heater is also in the game, I doubt cabling is an issue since they are not running the same way on a bigbox.
