Dual Extruder with single work cooling fan
Hi Repetier,
I've got two extruders but am only using a single print cooling fan with a nozzle directed under each hot end.
Firmware is the development 1.0.0dev
As both nozzles use the same print cooling fan I set both the "Print cooling fan pin" and "Print second fan pin" to the same output (heater 3).
Unfortunately with this setup the print cooling fan will not run. I've tried setting up both extruders individually with the other print fan disabled and it works fine. From this I'm guessing that the in use extruder is commanding the output "on" whilst the second extruder is simultaneously commanding the same output to "off".
Is this the case and is there a remedy for it (I haven't got any more outputs available on the control board).
Thanks as always for your patience and time.
Cheers,
