      Fan speed can be changed when printing, but as soon as the print G-code sets a fan speed, the change is undone. Is there an option to let the manual override become leading?

        On the DWC fan control there is a little "pin" button that lets you lock the fan value for the duration of the print. I don't think this is done with a specific gcode though. It would be nice if it were.

          If/when @dc42 accepts my Pull Request you could do this by setting both M106 Lnnn Xnnn parameters for the fan to the same value. This way the fan could only run at the given speed or being turned off.

            I have several PRs including yours to consider for release 2.02, however not much serious work on 2.02 is likely to happen until October, because we have a number of things to get ready for the TCT show at the end of September.

              The pin fan speed was new to me, but it's perfectly ok. Maybe in the future make the option available on the Panel Due, but consider it problem solved.for now.
