How would I change the config to use e1temp?
First, I’m sorry having confused the sensor and the heater port names 🤦
Now, in order to use a different heater port, you just have to change this line in your config
M950 H1 C"e0heat" T1 ; create nozzle heater output on e0heat and map it to sensor 1
to this:
M950 H1 C"e1heat" T1 ; create nozzle heater output on e1heat and map it to sensor 1
Your heater is still called H1, and it will still be mapped to sensor 1 (T1), but now, the Duet assumes the heater to be connected to a different port. That’s exactly what you have to do next: wire the heater to e1heat of the Duet.
