Temprature sensor error unknown temperature sensor channel

Are you sure you're using RRF3? Send M115 to verify your firmware version.

This is what I get from the configurator, which should work.

; Heaters
M308 S0 P"bedtemp" Y"thermistor" T100000 B3950     ; configure sensor 0 as thermistor on pin bedtemp
M950 H0 C"bedheat" T0                              ; create bed heater output on bedheat and map it to sensor 0
M307 H0 B0 S1.00                                   ; disable bang-bang mode for the bed heater and set PWM limit
M140 H0                                            ; map heated bed to heater 0
M143 H0 S120                                       ; set temperature limit for heater 0 to 120C
M308 S1 P"spi.cs1" Y"rtd-max31865"                 ; configure sensor 1 as thermocouple via CS pin spi.cs1
M950 H1 C"e0heat" T1                               ; create nozzle heater output on e0heat and map it to sensor 1
M307 H1 B0 S1.00                                   ; disable bang-bang mode for heater  and set PWM limit

I notice you have R395 F50 on the M308 line for the PT100 so maybe that's not right.

The PT100 sensor is the red wired one.

Are you sure you have the PT100 daughterboard? and are you sure it's installed correctly?

@Phaedrux Thanks for the reply, yes im pretty sure its a PT100 daughter board as its the new version with the jumpers just like the pic, also says PT100 RTD board on the board. I have it plugged in as per the pictures and also the wires are into the middle two terminals as per the pics on the link.
My firmware is :8:31:40 AMM115
FIRMWARE_NAME: RepRapFirmware for Duet 2 WiFi/Ethernet FIRMWARE_VERSION: 2.03 ELECTRONICS: Duet WiFi 1.02 or later FIRMWARE_DATE: 2019-06-13b2

I just tried deleting the R395 F50 line but still has the same error message. Thanks for replying it really is driving me up the wall lol

2.03

Ok there's your problem. You're still using a very old firmware version but your config file is using modern syntax.

You'll need to update your firmware.

If you have access to the web interface this will be easy and will consist of uploading 3 zip files, one for each firmware version we need to stop at along the way, 2.05.1, 3.0, and 3.1.1. After each upload it will install the new firmware and reboot. The web interface will get an update too.

https://github.com/Duet3D/RepRapFirmware/releases/download/2.05.1/Duet2Firmware-2.05.1.zip

https://github.com/Duet3D/RepRapFirmware/releases/download/3.0/Duet2and3Firmware-3.0.zip

https://github.com/Duet3D/RepRapFirmware/releases/download/3.1.1/Duet2and3Firmware-3.1.1.zip

Once you've done that update the firmware will understand the commands you have in config.g and things should start working.

Thanks so much for the help ! Ive uploaded two updates and the third came up an error? i see on my web interface the gcode console says updating firmware for two updates, taking a long time though is that normal?

Veti

what firmware version are you on now?

JTM

@Veti the first two are updating?

this is what comes up in the gcode console :
2:44:19 PMUpdating Firmware...
2:43:02 PMM997 S0:1
2:43:01 PMConnection established!
2:41:56 PMUpdating Firmware...

Update should be less than a minute. Reload page and try again; if page doesn't reload connect using USB and issue M997 command to repaet the update.

@bearer the wifi module has stopped working i plugged in the USB but cant load up the web interface ?

can issue the command over usb serial terminal? if not refer to https://duet3d.dozuki.com/Wiki/What_to_do_if_your_Duet_won't_respond

JTM

@bearer i dont know what ive done but i have connected via usb and using yat i cannot start the wifi as per the instructions on the link. I send the 552 S0 command and get ok, doesnt go into idle?

JTM

@bearer i get wifi module is being started?

A Former User

see this post; https://forum.duet3d.com/topic/18354/received-duet2-wifi-with-doa-wifi/6?_=1600236157757

if no change, run M997 S1 to reflash the wifi module and repeat?

JTM

i ran M997 S1 it reloaded the firmware, i finally have the blue led on for wifi but now i cant load the Duet web interface? the page is blank? my due panel works but i think the homing code has changed as my zprobe doesnt work it goes to manual?

This will likely do it. Sometimes the wifi firmware doesn't flash automatically. Doing it manually is usually enough to get it going.

This happened to me on a recent update and as soon as the wifi was reflashed it acted like nothing happened.

Phaedrux

When you were doing the initial updates did you upload the zip file as is, or did you extract them and use the M997 S1:0 to flash?

clear browser cache or visit it in incognite/private window?

alternatively remove SD card form Duet and extract https://github.com/Duet3D/RepRapFirmware/releases/download/3.1.1/DuetWebControl-SD-3.1.1.zip to the www folder on the sd card as described here https://duet3d.dozuki.com/Wiki/Installing_and_Updating_Firmware#Section_Updating_DuetWebControl_files

Phaedrux

If the web interface wasn't updated along the way with the firmware, you can manually install the DWC files by extracting the DWC zip file into the /www folder on the SD card with your PC.

https://github.com/Duet3D/RepRapFirmware/releases/download/3.1.1/DuetWebControl-SD-3.1.1.zip

JTM

@Phaedrux i extracted to documents then uploaded the lot from there?

Phaedrux

The zip files are meant to be uploaded as is. The DWC handles the extraction and firmware installation. This also ensures you have all the required IAP files and DWC files.

When you send M115 what does it say is installed for firmware version?

JTM

@Phaedrux version 3 now
