SOLVED BLTouch isn´t working after change to Duex 5

  • My BL Touch was working well till today as I´ve installed Duex 5 Board.
    I used the Heater 3 Pin to drive the servo of BLTouch.

    I have configured Heater 7 in Config.g
    M307 H7 A-1 C-1 D-1
    I didn´t touch the mode entry
    M558 P9 H5 F100 T2000

    If I send the Test Command the Heater LED is set on

    Any suggestions?

    Remove the I1 parameter from the M280 commands that you use to control the BLTouch in deployprobe.g and retractprobe.g, and anywhere else that you use them.

  • Thanks David,

    that was the reason. 🙂
