Cant home z in laser mode

  • Hi, I am having an issue in laser mode where when i try to home my z it will move all the way up but ignore the end stop. i dont have this problem if i switch to FFF mode.

    ; homez.g
    ; called to home the Z axis

    G91 ; relative positioning
    G1 S1 Z94 F1500 ; move quickly to Z axis endstop and stop there (first pass)
    G1 Z-3 F2400 ; go back a few mm
    G1 S1 Z94 F300 ; move slowly to Z axis endstop once more (second pass)
    G90 ; absolute positioning

  • In laser mode S sets the laser power, you need to use H instead to control the limit switch behaviour (can use H in FFF mode as well)

  • Thank you i will give this a shot i knew it had to be simple 🙂

  • @bearer thank you all working 🙂
