      Hi,

      I'm running the M3030 H1 S220 command to tune my hot end. It's running just fine, but it states that it is turning the fan on and off (OK, off).

      The extruder fan turns on normally. But I have a nozzle fan, and thought that would turn on. Should I turn that on manually?

      Am I missing a command line option?

      The nozzle cooler (Berd Air) is on F0 and I can happily turn it on and off via the touch screen.

      Not printing yet, but getting very close.

      Thanks.

      Michael

        Check the fan assignment in the tool section

          To tune the heater with the fan control, start with the fan off, and use M303 T0 S220 instead of H1. This will tune it as a tool and use the fan as part of the tuning process.
