SOLVED Hot end thermistors/thermocouples for duet 2 wifi
Just set up my duet and everything is working like a dream thanks to the great documentation provided. My last hurdle is the hot end temp read.
I’m running a hemera with a Semtec104. The hot end is connected to e0heat and the sensor is connected to e0temp. This is also reflected in the firmware. However my temps are at 2000c
Rereading the sensor documentation I clocked the use of the daughter boards. I’m now unsure wether this is required in order to use the Semtec sensor
I’ve ordered a p100 sensor and breakout board regardless as I intend to print at higher temps but could somebody shed light on wether a DB is required for the semtec heater or am I overlooking another detail.
Yet to pid tune as the reading was so far off
Appreciate your time
@siopshop the Semtec 104 thermistors do not require the daughter board. Connect them directly to the TEMP inputs of the Duet.

This is what I thought. The heater cartridge is on e0heat and the sensor is on e0temp. The heater parameters are also set to Semitic 104 gt.
The error I’m receiving is - temperature reading fault on heater 1: unknown temperature sensor channel
Will post up the config shortly
I’ve attached a pic of the board
Am I being a total idiot ?
@dc42 All sorted. Amazing platform. Amazing support.
@siopshop I'm glad you got it working.
