My latest config is uploaded Here is the respondse, but it does not make sense to me:

@MIke-1 now we are getting somewhere. We need to fix those errors.

Error: Unknown pin name 'duex.e1heat'

if you look in the documentation here:
https://docs.duet3d.com/Duet3D_hardware/Duet_2_family/Duet_2_WiFi_Ethernet_Hardware_Overview#pin-names

you will not find "duex.e1heat" the e1heat connector is on the duet 2 mainboard so change that to "e1heat" without the duex and then restart and run M98 Pconfig.g again

you will hopefully see that first error disappear and then probably the next two which relate to heater 1 not being setup correctly.

Next error, these three lines:
Error: Sensor 4 does not exist
Error: Bad command: mp"" Y"thermistor" T100000 B4138
Error: in file macro line 108: M308: missing parameter 'S'

This line is possibly the culprit
M308 S4 P"duex.e5temp" Y"thermistor" T100000 B4138

try the following in its place

M308 S1 P"e5temp" Y"thermistor" T100000 B4138

Once again save, run M98 Pconfig.g and lets see if thats fixed some more of the issues.

Using the same process have a a go fixing the other errors.

I updated the config but do not understand the issue.

The thermistor is the upper one with the 2 blue and 2 yellow wires just using 2

Once again save, run M98 Pconfig.g and lets see if thats fixed some more of the issues.

But why S1 in M308 S1?

sorry my cut and paste mistake. it should have been
M308 S4 P"e5temp" Y"thermistor" T100000 B4138

to replace this line
M308 S4 "P"duex.e3temp"" Y"thermistor" T100000 B4138 ; configure sensor 4 as thermistor on pin duex.e6temp

if S4 is actually connected to e3temp rather than e5temp then adjust the line accordingly.

I think this should work

M308 H4 C"duex.e3heat" T4 ; heater 3 on the extension board

Thanks a lot!!!

T3P3Tony

@MIke-1 that yellow and blue cable looks like its wired to a PT100 because its 4 wires not 2. but that aside, there is a fault in the config.g that it preventing the sensor from being created. looking at it with fresh eyes i think i spot the issue, there is another M308 in there which should be a M950

please replace this:

; Heater4

;M308 S1 P"e5temp" Y"thermistor" T100000 B4138
;M308 S1 P"e5temp" Y"thermistor" T100000 B4138

;M308 S4 "P"duex.e3temp"" Y"thermistor" T100000 B4138
M308 H4 C"duex.e3heat" T4 it to sensor 4
M307 H4 B0 S1.00 ; disable bang-bang mode for heater and set PWM limit
M143 H4 S280 ; set temperature limit for heater 4 to 280C

with this

; Heater4

M308 S4 P"e3temp" Y"thermistor" T100000 B4138
M950 H4 C"duex.e3heat" T4 it to sensor 4
M307 H4 B0 S1.00 ; disable bang-bang mode for heater and set PWM limit
M143 H4 S280 ; set temperature limit for heater 4 to 280C

I don't necessarily think we will get a correct temperature reading but we should get a configuration that stops failing at that point.

Also please update this table:

H1 T0 is linked to with 2 cables to E0Temp 9,4kOhm
H2 T1 is linked to the bottom board with the resistor 108Ohm
H3 T2 is linked with 4 wires connected to one of the top 150kOhm
H4 T3 is linked with 2 cables to E5Temp 9,4kOhm

because it looks like at least H4 is using S4 and is using a 4 wire sensor.

The T3 cable has 4 wire but is connected to only 2 pins on the board.

H1 T0 is linked to with 2 cables to E0Temp 9,4kOhm ;Sensor is on H1 and working
H2 T1 is linked to the bottom board with the resistor 108Ohm
H3 T2 is linked with 4 wires connected to one of the top 150kOhm
H4 T3 is linked with 2 cables to E3Temp 9,4kOhm ;Sensor is on H4 and working

Now it is time to fix the other 2 sensors

@MIke-1
T1 is working
M308 S2 P"spi.cs1" Y"rtd-max31865"

T2 is a 104nt-4-r025h42g should it be pluged into the board itself? How do I connect to that sensor?
M308 S3 P"spi.cs3" Y"104GT-2" is not working

Yes if it's a normal thermistor it needs to be connected to the board itself on a temperature input and not the PT100 daughterboard.

Then you'd need commands similar to these depending on what pin you use and what values are needed for the thermistor.

M308 S4 P"e3temp" Y"thermistor" T100000 B4725 C7.06e-8
M950 H4 C"duex.e3heat" T4 it to sensor 4

This is just an example though.

Can you post your config.g as it currently is now?

Mike 1

@Phaedrux

Now the heaters are all working
I used another plug for the sensor.

Sensorless homing is crashing at least for the x axis.

Might be a good idea to start a new thread about this issue. Include your config.g and homing files.
