Hello,
I have to control a fan which adds fresh air into my enclosure after printing. Apparently it is not possible to trigger an output when print ends. In addition this fan must be powered off 10 minutes after.

I would be great to have a checkbox in the outputs configuration section called "Start when print ends", and also "startup delay" and "shutdown delay" fields.

I found a (bad) workaround: I triger the GPIO output with a G-code command at the end of my G-code script, and I have an Arduino (connected to this GPIO output) which delays for 10 minutes (!!!!!). I do not want to pause my G-code script during 10 minutes to turn off the fan.

Thank you!

I support this. A timeed event would be very useful.

I also want to control a fan to cool my print after printing.

This would also allow to use the relais card connected to my Raspi that I use to switch on my printer and the light via Octoprint. I have two more relais free which could be used foe enclosure fan etc.
