    @Phaedrux Thx 🙂 i was too dumb to see that i have to change the motor directions and edit the homing files so that it goes in the right direction.
    Now this issue is solved, thanks a lot

  • Endstops High / Low & Homing fail

    I installed a Duet 3 Mini 5+ on an old 3D-Printer (German Rep Rap X400)
    This the first time that i configured the Whole config file and a did a few "Mistakes" in the config tool.

    I think i set the Endstops wrong, i should have set the endstops to "high endstops".
    In General the Printer works fine, but when i home the Origin is in the far right Corner, in the Slicer and Height-Map its in the Front left.

    ; Endstops
    M574 X1 P"io4.in" S1 ; configure X axis endstop
    M574 Y1 P"io1.in" S1 ; configure Y axis endstop
    M574 Z1 S2 ; configure Z axis endstop
    

    This is my Endstop configuration. When i switch to X2 and Y2, the printhead will "crash" in the endstops when i use "home all".
    I think he finds the Homing-Point the first time, but then crashes when he does the "move back 5mm" movement in the "homeall.g". But i am not 100% sure that it does not "crash" into the endstop in the first run.

    G91 ; relative positioning
    G1 H2 Z2 F6000 ; move Z relative to current position to avoid dragging nozzle over the bed
    G90 ; absolute positioning
    
    ; home XY
    var xTravel = move.axes[0].max - move.axes[0].min + 5 ; calculate how far X can travel plus 5mm
    var yTravel = move.axes[1].max - move.axes[1].min + 5 ; calculate how far Y can travel plus 5mm
    G91 ; relative positioning
    G1 H1 X{-var.xTravel} Y{-var.yTravel} F3000 ; coarse home in the -X and -Y directions
    G1 H2 X5 Y5 F6000 ; move back 5mm
    G1 H1 X{-var.xTravel} Y{-var.yTravel} F300 ; fine home in the -X and -Y directions
    G90 ; absolute positioning
    
    ; home Z
    var xCenter = move.compensation.probeGrid.mins[0] + (move.compensation.probeGrid.maxs[0] - move.compensation.probeGrid.mins[0]) / 2 - sensors.probes[0].offsets[0]
    var yCenter = move.compensation.probeGrid.mins[1] + (move.compensation.probeGrid.maxs[1] - move.compensation.probeGrid.mins[1]) / 2 - sensors.probes[0].offsets[1]
    G1 X{var.xCenter} Y{var.yCenter} F6000 ; go to bed centre
    G30 ; probe the bed
    

    Thats my whole homeall.g
    I am no pro and tried to find this case in the Forum but had no luck.

    Maybe you have an idea to fix this issue. I would appreciate the help.
