Core X-Y X moves wrong direction



  • Hi there,

    my y axis moves in the right direction, but my X Axis doesnt. If i change the the
    M569 P0 S1 ; Physical drive 0 goes backwards
    M569 P1 S1 ; Physical drive 1 goes backwards
    it all gets messed up dueto the core xy.

    so i need to tell the config only to flip the X axis. How to do so?

    Thanks

    EDIT: to make things more clear. i have a high endstop for x
    my homex:
    ; homex.g
    ; called to home the X axis

    G91 ; relative positioning
    G1 S1 Z5 F180 ;Sicherheitsabstand Z
    G1 S1 X320 F3000 ; move quickly to X axis endstop and stop there (first pass)
    G1 X-5 F6000 ; go back a few mm

    G90 ; absolute positioning

    and in config.g

    ; Axis Limits
    M208 X0 Y0 Z0 S1 ; Set axis minima
    M208 X250 Y250 Z350 S0 ; Set axis maxima

    ; Endstops
    M574 X2 Y1 Z1 S0 ;set endstop x high end y and z low ends





  • Ty!
    maybe this section indeed helps:

    
    ```For a CoreXY or H-Bot machine, RepRapFirmware assumes that the motor connected to the X motor output moves the head in the +X and +Y directions when it runs forwards, and that the Y motor moves the head in +X and -Y directions when it runs forwards. [Note: firmware 1.18 and earlier assumes that the motor connected to the Y motor output moves the head in the -X and +Y directions when it runs forwards]. So you can start with these M569 commands in config.g:
