  • @Chrabban said in Some help with Bltoutch:

    M280 P3 S10

    so when you issue this command manually nothing happens?

    there have been many reports with bad cabling on the bltouch side. check the crimp job of those wires.



  • @Veti

    Nothing happens when i try that command
    Allt the cables is good, just tried them with my multimeter 😕

    And you're certain you're using heater pin 3 as the servo control pin?
    And you're certain you have the heater pin 3 unbound as a heater in config.g?
    And you're certain you have no commands for heater pin 3 in config-override.g?


  • administrators

    As you are not using a DueX expansion board, you need to add parameter I1 (that's letter-i digit-1) to the M280 commands in deployprobe.g and retractprobe.g. See https://duet3d.dozuki.com/Wiki/Connecting_a_Z_probe#Section_Software_setup_Duet_2_WiFi_Ethernet_running_RepRapFirmware_Num_2.



  • it is working now 😄 it was the I1 that was the last thing, tnx for all the help 😄
