    this is not valid in rrf3

    M308 S1 P"e0temp" Y"thermistor" T100000 B4138 ; configure sensor 1 as thermistor on pin e0temp

    B4138 is incorrect. find the correct value in your thermistor documentation.

    one is zprobe won't deploy

    you did not post your deploy script.

    other is driver disconnected

    what does that mean?

    mesh leveling carriage goes violently to side than front etc

    does normal movement work ok?

    did you acutally update to rrf3 ?

    You've set a travel speed between probe points of 200mm/s which is a bit high. That could explain the violence.



  • @Phaedrux yes that makes sense and sorry for the ill-informed post I was at work and trying to remember what errors I was getting last night what info do you need



  • @Veti yeah the true value is actually in my config.override the only two things in there is the PID tuned for h1 and h2 didn't seem the need to post that since I was at inquiring about the BL touch and z homing



  • @bks31 said in bl touch:

    yeah the true value is actually in my config.override

    what true value?



  • @Veti my bad sorry I was working and confused but somehow when I got home i must of switched my config file or something but everything was off got everythimg homing right and got bed heater and sensor working but heater is showing -273 °c I changed the thermistor checking for a short but that's the the case I ran a m98 and says missing p paramater not sure where tho but what should my h1 look like ; Configuration file for Duet WiFi (firmware version 3)

  • @bks31 said in bl touch:

    m98

    M98 P"config.g"

    what should my h1 look like ;

    i dont know what you are referring to.



  • @Veti my heater config you said earlier b value doesn't belong trying to get my heater #1 for hotend not to fault



  • i said the beta value is incorrect.
    that is not for the heater but for the thermistor. the temperature measuring device.
    the beta values is used to determine the actual temperature.
    if you have a wrong value, the actual temperature will differ from the one displayed



  • @Veti yea I get that but wouldn't that cause for my heater to throw error code sorry let me clarify what would be the correct parameter for my hot end thermistor because temp shows -273



  • @bks31 said in bl touch:

    what would be the correct parameter for my hot end thermistor because temp shows -273

    find the correct value in the thermistor documentation





  • that file is protected





  • please link to the actual amazon page.
    maybe its in the description





  • its written in the details

    Negative Temperature Coefficient (NTC) Thermistor Model: B3950
