X and Y motors not moving

samlogan87

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?

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.

@samlogan87 said in X and Y motors not moving:

this is what I have in there

M584 X3 Y4 Z2 P3 ; Driver 0 For X, 1 for Y, Z=2:3:4 U3 V4, Extruder 5 :0:1 U3 V4 E5
M350 X16 Y16 Z16 E16 I1 ; Configure microstepping with interpolation :16:16 U16 V16
M92 X80 Y80 Z400 E420 ; Set steps per mm :400:400 U400 V400
M566 X150 Y150 Z12 E120 ; Set maximum instantaneous speed changes (mm/min) :12:12 U12 V12
M203 X150 Y150 Z180 E1200 ; Set maximum speeds (mm/min) :180:180 U180 V180
M201 X250 Y250 Z250 E250 ; Set accelerations (mm/s^2) :250:250 U250 V250
M906 X850 Y850 Z1850 E800 I50 ; Set motor currents (mA) and motor idle factor in per cent :1850:1850 U1850 V1850
M84 S30 ; Set idle timeout

Does it look correct?

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?
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.

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?

samlogan87

Sure can.

Here they are

M906
Motor current (mA) - X:850, Y:850, Z:1850, U:1850, V:1850, E:800, idle factor 50%

Phaedrux

This is why

; Automatic power saving

M911 S10 R11 P"
M913 X0 Y0

M913 is dropping current to 0%

samlogan87

You are an absolute genius. It works.

Thank you so much. I really love this forum

Phaedrux

Aww shucks.

Now maybe I can sleep because that was bugging me.

whosrdaddy

Nice catch!
This one was bugging me too

samlogan87

Yeah I have no idea why that line was in there. I copied the restart on power fail from somewhere and it must have been in there. Oh well I am really happy you guys have sorted it for me. I was starting to get a bit deflated.
