Stepper Motor x and y Duet 2 Wifi

one People on Facebook say
i had the same problem, but by double checking the wiring as showed on the duet website i solved the problem.
where can i find this?
my english is so bad and it is very havy for me.

@sven Wiring diagram is here: https://duet3d.dozuki.com/Wiki/Duet_Wiring_Diagrams

If the same motors work on E0 and E1, I don't think it is wiring.

Is this your config.g, or has someone sent you this? What error do you see when you try to move X and Y motors? 'Axis not homed'?

sven

this is from me from "Go to Settings > System editor (Einstellungen > ???) and select config.g" what you say, i do this

sven

i have a Video but i can not send it to this Forum

sven

i send it to YouTube
you can hear the steppermotors
the Name from the Video is Mgn cube fehler

@droftarts this is what i have but so the steppermotors not run on the plugs for y or x, on e0 and e1 run the same steppermotors.

sven

Hello, has nobody got an idea or is the board broken? The motors on the other contacts only go to drive 1 and drive 0. Why?
It is new and it was the first time I tried to start to see if the motors were working. the mgn cube is still in the works but i can't get any further. there are no endstops and no fan. can it be because of it?

@sven DO NOT USE THE MACROS ON THE SD CARD FOR TESTING YOUR MACHINE! Follow the commissioning advice here: https://duet3d.dozuki.com/Wiki/Step_by_step_guide#Section_Commissioning_tests

I can see in your video you are running the '04-Test_motors' macro from the SD card. This is for testing the Duet at the factory, not for testing your machine. It sets the motor current very high, as well as trying to move the axes at high speed, and for 2 metres! In the test rig at the factory, it is just a motor, not connected. The 'motor phase disconnected' message is because it cannot move your X and Y axes so fast. Also, the stepper motor current is set to 2A, and is not reset to 1.6A (which your motors are set to), so your motors may get hot. Reset the Duet and don't use these macros.

For those interested, this is '04-Test-motors':

your motors

okay i will test this. how can i reset the Duet an how can i test?
Thank you i will Response later.

droftarts

@sven If you want to test motor movement with no endstops, you need to send a command that will allow you to move the motor without homing, or give the axis a position. I find the second one easiest. First, reset the printer (turn off power, turn on, or send M999, or press 'Emergency Stop' top right in DWC) so you use the motor settings in config.g. Then move the X and Y axis by hand to the centre of the bed. Then send:
G92 X150 Y150 Z 50 ; set position
Then use the buttons in DWC, eg X+10, Y+10, Z+10 to move each axis.

As you have a CoreXY, you MUST read this to get the movement correct: https://duet3d.dozuki.com/Wiki/ConfiguringRepRapFirmwareCoreXYPrinter

I did everything so nothing happens. only z is move. in x and y is no move, z works fine.

droftarts

@sven Any error message? Does the X and Y position reported in DWC change?

Ian

sven

No if i press + or - any in the web interface it do Nothing happens. only in z is Motion

what fan it mean. fan 0? if i put a fan on the board it works???
please i Need help, i am a newbee and want to build this Printer.

Sounds like the wiring of the X and Y motors may not be correct. Identify which pairs of wires are phase pairts on your motor, and make sure you connect one phase pair to the 2 pins at one end of the 4-pin motor connector on the Duet, and the other phase pair to the 2 pins at the other end.

Hello,
but why the same Steppermotors run on drive 3 (e0) or drive 4 (e1)
only on drive 0(x) and Drive 1 (Y) they do not run.
no other Motors, the same they not work on x and Y. The plug is only move from port to port.
I have test it, the pairs are Black and Green, Blue and Red. I have crimp the wire new. if there is not a bad crimp.
But i will do this and test it later one more time.

In that case, it sounds like faulty stepper drivers - although getting 2 failing so quickly on a single board would be most unusual, unless they were initially wired incorrectly.

so the board is new. I just plugged in the new motor connectors and tried to move the motors. but this was not possible. I contacted the seller who sent me to the forum and the BLV forum. Where I got the same answers as here. Check crimp, test phases.

droftarts

@sven Where did you get the config.g file you are using? Is it from BLV MGN community? It is a complicated config.g. If you don't understand how this configuration works, it is going to be very difficult for you to build your printer. You need to read the documentation; translate it with google. Unfortunately it is not 'plug and play'.

No, you do not need a fan connected. Are you pressing the fan +/- buttons?!

I'm not sure why you are getting the 'Error: over temperature shutdown reported by driver(s) 1' message. Did you reset the Duet after running '04-Test_motors' macro? This may overheat the Duet if you left it for long enough.

Please replace your config.g (make a copy of it first) with the one below.

This is a simple config.g, just for testing motor movement. It creates 5 axes; X, Y, Z, U, V. Connect one motor to each stepper motor output. Best with just the motor, no axis connected. When you reset the printer, and connect to DWC, you will see 5 motor axes. Use these buttons to test movement of each motor:

DO NOT connect/disconnect motors when the Duet is powered on. This can damage the stepper drivers.

Let me know which motors work. If that still does not help, please post a picture of your Duet and wiring.
