use PT100 sensor for extruder 0 sensor

  • hi all
    I want to know if I can use PT100 with PT100 Daughter Board for extruder 0 tool 0 sensor
    what the command I should to use
    I try to use command M305 but I think this command for bed heater .
    also I try to connect PT100 direct to tool 0 sensor but it give me wrong reading for temperature
    so can any one tell my witch command define tool sensor

  • If you're having issues with making the configuration with the web based reprap configurator, try V1 instead. I ran into all sorts of trouble when trying to set up PT100 with the new.

    I think I saw a thread that may have fixed the issue, but I haven't tried it myself.

    But yes, I use PT100 on daughterboard for both bed and extruder.

    ;H0 = bed
    ;H1 = E0 hotend
    M307 H0 B0 P1 F10 V0                                 ; 10Hz PID, ignore voltage compensation (mains powered)
    M305 P0 X201                                         ; Configure thermocouple for heater 0
    M143 H0 S120                                         ; Set temperature limit for heater 0 to 120C
    M301 H1 S0.70                                        ; Set heater 1 PWM limit to 70%
    M305 P1 X200                                         ; Configure thermocouple for heater 1
    M143 H1 S280                                         ; Set temperature limit for heater 1 to 280C

  • yep it's work
    before that I try command M305 more then 100 time and it's won't work
    after I restart the controller I use command M305 P1 X202 and the magic happen from first time 🤔 🤔
    thanks ☺ 👌

  • Do you have two PT100 boards, or is M305 P1 X202 meant to be something else?

  • yes I have two PT100 boards
