X and Y motors not moving

[samlogan87]

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?

[samlogan87]

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

[Phaedrux]

Can you test without your additional axis defined?

[samlogan87]

Yeah just tried it and nothing.

[samlogan87]

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

[Phaedrux]

How are you trying to move the motors?

If you send this does the motor move?

G91
G1 S2 X10 F3000

[samlogan87]

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.

[samlogan87]

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

Does it look correct?

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

[Phaedrux]

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

[samlogan87]

Yeap I did that.

G1 S2 X100 F1000 and it did not move at all

[Phaedrux]

Sorry, I meant the M584 command

[Phaedrux]

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.

[samlogan87]

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

[Phaedrux]

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

[samlogan87]

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

[Phaedrux]

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