Duex Heater 3
-
I havea Problem with my Duet/Duex Combo, the duet is a V1.03 und the duex5 a V0.8a.
this is my second printer and i played the firmware from my other one on it. There are the boards both the newest ones.
No my Problem, the Heater 3 Output of my duex is allways on and has 24V.
Could it be that i have to change some things in the firmware? Because i dont even have configured heater 3 in the firmware at all.

Ok i found out that my other printer does exactly the same, so i think i have something conrigured wrong

you have to invert the heater outputs I believe using !

Yes it sounds like a heater pin is inverted, or needs to be inverted. Post your config.g please.

I found the error, i got the firmware from a friend and he used a Chamber heater that is allways on. I turned it off and everything is fine now
