What is x and y axis & how to switch them?



  • Hi
    I am trying to get my corexy to be configured correctly. I am assume that y-axis in the + direction is moving towards me (standing in front of the printer) and that the x-axis is moving to the right in the + direction… But now the +y-axis is moving to right and the +x-axis is moving towards me.
    Have tried to switch the motor connectors on the board (duet 0.8.5) and it dont change the axis.
    I could get the axis to move in the opposite directions but I want to change the y-axis for the x-axis.
    And I dont know how!
    Or do I have the right axis configuration? On my cnc-router the axis are the opposite...
    Plz help needed!

    Hi Per

    Have you checked the documentation:
    https://duet3d.com/wiki/Configuring_RepRapFirmware_for_a_CoreXY_printer

  • If it's a standard layout corexy the x axis is going left to right with 0 at the left, and the y axis going front to back with 0 at the front. How to set this up on duet I don't know, I only got mine yesterday.



  • On my corexy: 0,0,0 is at the front left corner. X moves left/right. Y moves front/back.

    With 0,0,0 at your left. X & Y motors in the rear. Y motor is the left side motor and the X is the right side motor.
    M569 P0 S1 ; Drive 0 goes forwards
    M569 P1 S0 ; Drive 1 goes backwards

    If pictures will help, I put my printer design at http://www.thingiverse.com/thing:1470253

    Use the M569 command to select the directions of the X and Y motors - see the documentation on the wiki. If none of the 4 possible combinations gives you the directions you want, exchange the X and Y motor connections.



  • Hi all!
    So, I had the right idea how the axis should work, and after the 7:th combination and switched x & y motor connections I finally found the right settings!
    Thank you so much for your patience and great answers to me who´s just starting to understand the in´s & out´s of Duet and reprapfirmware!
    Best regards
