BL-Touch don´t trigger by Home Z

  • CupaCabra

    I have a other Problem with my Printer and BLTouch.
    I home X and Y, in the second step are Home Z.
    The Bed go´s UP but wehn i Trigger the BL-Touch mith my Finger the Pin are stif and the Bed want chrash into the BLTouch.

    my HomeZ config

    @CupaCabra
    Have you edited also the homeall.g?
    You have to change the M98 for calling the macros for deploy and retract...

    your thermistors are configured wrong. that is the default and incorrect for your thermistors.

    As far as I could see the deploy and retract of bltouch is missing on homeall.g.

    Ok, i change the Config.g

    but the thermistors shows the Temp. right.

    i use the PT100 Thermistors

    that is in no way reflected in your config.

    @DIY-O-Sphere are not in the G30 deploy and the retract command inside.

    @CupaCabra
    And where do you call the G30?
    It's not incuded in the homeall.g

    Normaly it would look like this:

    PT 100 would be configured like this (change the spi to match the correct terminal)

    M308 S0 P"spi.cs1" Y"rtd-max31865" ; configure sensor 0 as thermocouple via CS pin spi.cs1
    M950 H0 C"bedheat" T0 ; create bed heater output on bedheat and map it to sensor 0
    M143 H0 S120 ; set temperature limit for heater 0 to 120C
    M307 H0 B0 S1.00 ; disable bang-bang mode for the nozzle heater and set PWM limit
    M308 S1 P"spi.cs2" Y"rtd-max31865" ; configure sensor 1 as thermocouple via CS pin spi.cs2
    M950 H1 C"e0heat" T1 ; create nozzle heater output on e0heat and map it to sensor 1
    M143 H1 S280 ; set temperature limit for heater 1 to 280C
    M307 H1 B0 S1.00 ; disable bang-bang mode for the nozzle heater and set PWM limit
    M308 S2 P"spi.cs3" Y"rtd-max31865" ; configure sensor 2 as thermocouple via CS pin spi.cs3
    M950 H2 C"e1heat" T2 ; create nozzle heater output on e1heat and map it to sensor 2
    M143 H2 S280 ; set temperature limit for heater 2 to 280C
    M307 H2 B0 S1.00 ; disable bang-bang mode for the nozzle heater and set PWM limit

    but if you get output without this, this strongly indicated that you do not have pt100 sensors.
