trouble with homing the x and y axes on a core xy printer.



  • Hello all.
    I am currently working on a Core XY setup for which the decision was made that a duet WIFI paired with a Duex5 should be used for the brains. RRF configurator was a usefull tool to generate the first configuration for the machine(RRF3.1.1 and DWC 3.1.1). However, once I achieved the right orientation for the xy gantry, by testing the "G91 /G1 H2 X10 F3000", and the "G91/ G1 H2 Y10 F3000" , and decided to go further with the attempt to home the xy gantry to no avail. The A and B motors are "stiff"( if I try to rotate them by hand , I cant), as if one would try to turn opposed to the other.

    The config.g settings look like this:

  • you did not post you entire config.

    its unclear if you enabled corexy mode.

  • @campeancalin said in trouble with homing the x and y axes on a core xy printer.:

    G91 /G1 H2 X10 F3000"

    if this moves only in the X direction, then you do not have a corexy machine

    and decided to go further with the attempt to home the xy gantry to no avail

    what do you mean by that? there was no movement?
    the homing code does the same thing as your manual move in the first command.

    please post the output of m122



  • @campeancalin said in trouble with homing the x and y axes on a core xy printer.:

    In you config.g file you have this:

    G31 P500 X10 Y10 Z3.5 ; set Z probe trigger value, offset and trigger height

    As I recall for a BLTouch P500 should be P25

    And are you sure those X10 and Y10 offset values are correct?

    I designed my own hotend mount and the closest I could position the BLTouch was X0 Y25.


    Also for testing you can use M564 to allow using the DWC jog buttons before homing as been done.

    The possible parameters to M564 are H and/or S (see below):

    H1 = forbid movement of axes that have not been homed, H0 = allow movement of axes that have not been homed

    S1 = limit movement within axis boundaries, S0 = allow movement outside boundaries

    So issuing M564 H0 would allow using the jog buttons, M564 H1 would restore things to normal.

    RepRapFirmware for Duet 2 WiFi/Ethernet version 2.03

    there is your problem. you are not on RRF3.1.1 as you have written



  • @Veti said in trouble with homing the x and y axes on a core xy printer.:

    Duet 2 WiFi/Ethernet version 2.03

    ok, I might have confused it with the config tool version.



  • @fcwilt do these commands work if the version of the firmware is 2.03?



  • @campeancalin
    your config file does not work with RRF2



  • @Veti Can you be a bit more specific?



  • @campeancalin

    the pin configuration syntax only works in rrf3
    M574 X1 S1 P"xstop" ; configure active-high endstop for low end on X via pin xstop
    M574 Y1 S1 P"ystop" ; configure active-high endstop for low end on Y via pin ystop

    Yes they do.


    But a set of files generated for v3 firmware will not work with v2 firmware without some changes.

    I would go ahead and update the firmware to v3.

    First update using Duet2and3Firmware-3.0.zip.

    When asked allow it to update.

    Then update using Duet2and3Firmware-3.1.1.zip

    When asked allow it to update.

    You can upload each ZIP file on the System page.

    Once you update to 3.1.1 your current config has a better chance of working.

    You should probably redo the motor direction tests for corexy after you update.

  • Thank you kindly. I was not aware of these differences

    Since you're starting from scratch it doesn't much matter, but here are the details.

  • Hello guys,
    Thank you again for the heads up regarding the differencies between the machine config and the firmware that was on the board.
    Today I went on and upgraded the firmware on the board, and reuploaded the machine config. At a first glance, the xy gantry seems to move in the right direction ; I still cant perform the homing on them. I also moved the z axis, on which I have 2 in series motors ( ZA and ZB are being used to control them), and while the z axis is performing the required movement , the E0 extruder motor is also moving.
    Bellow you can see the M122 report:

    which I have 2 in series motors ( ZA and ZB are being used to control them),

    this does not match your config
    M584 X1 Y0 Z2:3 E4:5 ; set drive mapping; INIT:X=0; Y=1; Z2;E3:4

    Za and Zb are both driver 2



  • @Veti Thank you



  • The motors work fine, I still cant home the x and y



  • can you describe in detail what happens when you press homex



  • @Veti both motors receive current but the gantry does not move.



  • the x motor has an atempt to make a move , but to no avail.



  • @campeancalin
    does it work with no belts?



  • @Veti no, there's an atempt to start but it suddenly stops
