Solved Extruder heater not showing up on DWC.
-
@jay_s_uk ummm,
That seems to be the Duet Firmware which should be the same DWC?Firmware: RepRapFirmware for Duet 3 MB6HC 3.3 (2021-06-15)
That has both the BED and the Extruder at the same temp now.

@kcress ah, it's on the general settings tab.
Your config looks correct in that it uses temp0 for the bed and temp1 for the hotend. So I would be looking at your wiring now.
You're also probable not using B4138 thermistors so you need to update your config with the correct thermistor information. -
Thanks.
The thermistors might be correct. Because I couldn't tell if they were the same or not I turned on the extruder heat, (50W), that got up to that fairly quickly while I was looking for the DWC version.Aw yes! I see it now. Thanks. Man-o-man, I looked for it everywhere - I thought.
Duet Web Control 3.3.0

Can't see a HW issue. I unplugged them from the original controller and moved them over to the 6HC.
One sez "E Temp"
the other "Bed Temp"

@kcress can you take a picture from another angle? It's difficult to see where the wires go.
Do you have the config from the other controller so you know what the right thermistors are? -

Still both are called "Heater 1" and I think show the extruder temp.

Take out the second M140 that has H1
M140 is specifically for the bed heater, not extruders.

A come-back note:
Noting that the heaters were reading too low. With the original Vivendo Troodon M308:
M308 S0 P"temp0" Y"thermistor" T100000 B4138 C0 R4700 ; define bed temperature sensor
The temperatures were corrected by removal of "R4700"
which is a compensation for what divider resistor is used on the Duet board or clone. Removing the R4700 and leaving it the default (whatever it is on the Duet 6HC) corrected the temp readings. -
@kcress thanks, yes they are 2k2 resistors on the 6HC which is why the documentation recommends not putting the R value in in recent firmware as the defaults should be correct.
