X and Y motors not moving



  • Hi there everyone,

    I am having issues with the core xy printer that I am building. I am running 3x Z axis Nema 23 motors that are working fine, but the X and Y axis are not. I have tried switching the motors to the Z drivers and they work. Z axis ones do not work on drivers 0 and 1. I have a DueX2 and have put the x and y motors on there and it still does not work. I am thinking it could be something to do with the config. Can someone cast their eye over it and see if they can see anything.

  • If you send M584 with no parameters in the console what do you get back?



  • Hi there,

    This is what I get:

    11:51:28 AM M584
    Driver assignments: X0 Y1 Z2:3:4 U3 V4 E5, 5 axes visible

    Regards,
    Sam



  • Can you test without your additional axis defined?



  • Yeah just tried it and nothing.



  • this is what I have in there

    Does it look correct?



  • I have done some more troubleshooting. When I remap the extruder to one of the x and y drivers it works as it should. I can use the extrude and retract buttons to make the x and y axis to move. When I remap it back, I can not get it to home. The Z axis moves as it should, but the x or y won't move



  • How are you trying to move the motors?

    If you send this does the motor move?

    G91
    G1 S2 X10 F3000



  • Currently I have just been trying to get it to home the axis. I have the homing g code files from the configurator and when I run it, the Z axis shifts up (down in my case being a corexy) and then nothing for the x and y until I push the end stops in. Once I do this, the z axis then moves again. It says that the axis have homed and when I try and shift it, nothing happens.

    I will give that a try and let you know.



  • I gave that a go and it doesn't move.

    1. Please clarify: do you have X and Y mapped to drivers 3 and 4 as here, or mapped to drivers 0 and 1 as in the config.g file you listed in your first post?

    2. You can send following commands to test the X motor individually:

    G91 ; relative movement
    G1 S2 X10 F1000 ; move the X motor forward 10mm
    G1 S2 X-10 F1000 ; move the X motor back 10mm

    Similarly for the Y motor.



  • @dc42 said in X and Y motors not moving:

    G1 S2 X-10 F1000

    Hi there,

    Yes sorry it is as the above configuration. I was just making sure in that bit, that it was not a motor issue by mapping it to other drivers. Turns out the motors are fine.

    I tried that and nothing. They do not move at all.

    I am very confused as they turn when I set them up as extruders and use the retract button on the UI



  • Just on a lark, can you delete the entire line and type it out again from scratch?



  • Yeap I did that.

    G1 S2 X100 F1000 and it did not move at all



  • Sorry, I meant the M584 command



  • Also, are you sure the x and y steps per mm are 80?
    You said when you switched them to be extruders they worked but the extruder steps are 400.



  • Sorry I typed M584 and got

    M584
    Driver assignments: X0 Y1 Z2:3:4 U3 V4 E5, 5 axes visible

    I tried changing the steps per mm to 800 and it just sits there and hums



  • If you replace your m584 command in config.g with just M584 X0 Y1 and nothing else do they work then?



  • Tried that and still nothing. Sounds like it wants to move but it doesn't do anything unfortunately



  • Can you send M906 and verify that the motor currents are being accepted?
