Heater 1 not shutting off
-
I am setting up a Duet 2 wifi with a Duex 5, I have everything hooked up the way I want it but on my Heater 1 when it reaches temp it does not shut off it keeps heating until the board throws an error. Both of my hotends are volcanos. I have even tried changing heater 1 to another heater output and still the same problem.

I found the problem when I ran the pid tunning it didn't tune correctly I was running M303 T0 S245 and it did fault a few times before I could get it to tune. I just ran M303 T0 H1 S245 and it tuned a lot better I can now turn the heater on and it holds where it is suppose to.

@silver1882 said in Heater 1 not shutting off:
M303 T0 H1 S245
That's a mish mash of two commands, so I wonder which it actually ran.
M303 T0 S245 would tune the tool itself using the associated heater and cooling fan to try and account for any temp losses from the fan.
M303 H1 S245 would tune heater1 without fan input.
Do you remember what faults you got?

It said that it was heating up to slow, at present I do not have a tool fan hooked up so it did give an error that the temp wasn't dropping from the cooling fan.
-
Ok that makes sense. M303 H1 S245 is what you'd want in that case.
