@Caveman said in want to use E1 instead of E0 for heating.:

M308 S1 P"e0temp" Y"thermistor" T100000 B4725 C7.060000e-8
M950 H1 C"e0heat" T1 ; create nozzle heater output on e0heat and map it to sensor 1
M143 H1 S280 ; Set temperature limit for heater 1 to 260C

Change M950 H1 C"e0heat" T1 to M950 H1 C"e1heat" T1

And change the wiring obviously.

Caveman

thanks a lot. it's working again!!!

Caveman

ehm nope still having an issue fans not working on my duet

Phaedrux

You're going to have to be more specific.

Caveman

none of my fans are working i gues fuse is blown?

Caveman

yep crap it is blown. hope I can find one here

Caveman

and how di I do pid for bed in rrf3.2?

Phaedrux

Maybe stick to RRF 3.1.1. Setting up a new build with a beta firmware isn't the best way to go about it.

The heater tuning algorithm has changed in 3.2.
