    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

    You'll have to do this.



  • @Phaedrux im hopeless at this stuff ! i loaded that file onto the sd card and now i get this message from the web face

    Your Duet rejected the HTTP request: page not found
    Check that the SD card is mounted and has the correct files in its /www folder



  • @JTM said in Temprature sensor error unknown temperature sensor channel:

    i loaded that file onto the sd card

    you have to upack the zip file

    the content of the zip file has to be in the folder www on the sd card



  • @Veti i extracted those files to the sd card www file? is that right?



  • @Veti i switched it on and off and now its working !!!! i have web interface again !



  • now my zprobe doesnt deploy 😞 on the bright side the temp probe is showing temp, but when i tried to heat the hotend i got an error it was too slow.

    Alright you're getting somewhere.

    Have you uploaded the 3.0 and 3.1.1 zip files?

    @Phaedrux said in Temprature sensor error unknown temperature sensor channel:

    Alright, if 3.0 is installed you should try replacing the DWC files with the zip linked above. That may get you back on track.

    Once in the web interface, just upload the whole 3.0 zip file as is to the /sys folder in DWC. Then upload the 3.1.1 zip file. Don't extract them first.



  • @Phaedrux yes mate, when sending the M115 command i now get firmware 3.1.1

    The heaters will need to be PID tuned. That should get rid of the too slow error.

    Here's how: https://duet3d.dozuki.com/Guide/Ender+3+Pro+and+Duet+Maestro+Guide+Part+4:+Calibration/40#s161

    For the probe please post your config.g and deployprobe.g and retractprobe.g macros from the /sys folder. Also homeall.g

    Copy and paste the text here.

    In the deploy and retract files change the P3 to P0 and remove the I1



  • @Phaedrux i changed the macro test files to P0 and delted the I1 but didnt work, re added the I1 and the macros work, but when i try to home z i get this error message?
    G28 Z
    Error: in file macro line 9: G30: Z probe 0 not found

  • thanks everyone for your help, it is really appreciated !

    Does that line in your config.g actually have double M558 at the start?

    Can you post your full config.g?

    You've got M558 in there twice. Take one of them out.

    That should be B57600 not 8

  • @Phaedrux Thanks for the help mate, did as you suggested and went to home all axis and got

    G28 X
    Operation has been cancelled

    I suggest going through this guide to ensure endstops are working and motors are moving are going the right direction.

    https://duet3d.dozuki.com/Guide/Ender+3+Pro+and+Duet+Maestro+Guide+Part+3:+Commissioning/39



  • @Phaedrux Thanks for all your help Mate, still going through the checks, the motors and end stops seem to all be wired correctly and moving the right way, i keep getting this message when homing z

    G28 Z
    Error: in file macro line 9: G30: Z probe 0 not found
    Error: Homing failed

    i will keep looking 🙂 the M280 deploy and retract macros work but homing doesnt activate the probe so im guessing the Gcode for homing is missing something?



  • please post your revised config so we can see your current M558 line that configures your z probe

  • i think you might need C"^zprobe.in" added to the line with M558?

    M558 P9 C"^zprobe.in" H5 F100 T2000 ; set Z probe type to bltouch and the dive height + speeds

    edit: presuming thats where your zprobe is connected?
