@T3P3Tony u may got any idea ?

Try removing the D2 from the M569 commands in config.g.

Wont change anything. Started without and just added it as a hope it would help.

Does the white connector and the black connector go to the same model of motor?
If so, one of them has to be wrong.
- The white connector is wired as though Red-Green and Blue-Black are coils.
- The black connector is wired as though Red-Blue and Green-Black are coils.
Those cannot both be true (if the cables are consistent on the other end, and plug into the same model motor).
Please show a photo of where the white cable plugs into the motor and similar photo for the black one.

There is no connector on the motor.

This is my test Setup now because i need my printer working.
Using generic 200steps/rev motors.

@Danal Those steppers come pre-wired. They don't plug in with JST on the motor side.

It looks like the jumpers bridging the second (parallel) z stepper connector are missing.

iam using 2 z steppers. but neither of them is connected because of the problems i have ..atm just x and y are conncted.

Have you disabled the z motors in the config while they are not connected?
Also, can we see a shot of the underside of the board just to make sure there is no accidental bridging there affecting your board?

As seen in my config i didnt disable them. But i got the same erros with both of them connected. The underside is completely clean and doesnt touch anything conductive.

You say you try to move them, but do the motors actually move? I'm curious, as on my HEVO I get these warnings nearly every print for no apparent reason. The printer runs hours and hours without issue, but these warnings keep randomly coming. It's mostly for Drivers 0, 1 but also sometimes 2 and so on. This started happening some time after I switched to 0.9 steppers.
I've been checking connections and ignoring this for months now. I use these motors: 17HM19-2004S on firmware 2.02 tho. I have a suspicion that at some point the console is flooded with these messages, but I couldn't verify yet because so far the web app crashes during the night.
Fun fact, I've had one different ACT motor (out of two) short out between phases one hour into the print without apparent damage to the Duet a year ago. I've stopped using them since.

No mine dont move at all. Sadly.

@DruckKlaus have you told the printer it is homed before trying to move the motors (Or issued the cmd to override that safety feature)

i try moving the motors by trying to home.
-
add M564 H0 to config.g to allow axis movement before homing for testing

The problem is rly just about the drivers.

Understood that the motors just have wires, no connector.
Still, if these are going to the same model of motor, they cannot BOTH be correct. If you numbered the pins on a duet motor connector 1234, the coils are 12 then 34.
For example the left connector 12 are blue-green. In the right connector blue is in 3 (which puts it in the 34 coil) and green is in 2 (which puts it in the 12 coil). One or the other of these connectors has to be wrong.
Therefore, try this method of finding coils:
With the motor wires not connected, spin the spindle between your fingers. Short two of the wires together, then spin the spindle again. If it is much harder to spin than before, those two wires belong to the same phase (coil).
-
@Danal u saw the pictures above? The phases are 11 22 on both motors...

The wiki page describing how to wire steppers is confusing. First, when identifying the stepper motor phases, it states:
There should be a few ohms resistance between two wires that belong to the same phase, and no continuity between wires that belong to different phases.
So, assume a stepper with green/black/blue/red wires, and there's a few ohms resistance between green/black, and a few ohms between blue/red (but no continuity between any other combinations.)
So, that means that green/black belong to the same phase and red/blue belong to the other phase, right?
Earlier in the same page, it states:
. You must connect the two wires for one phase of the stepper motor between the two pins at one end of the connector, and the wires for the other phase to the two pins at the other end.
Based on an earlier determination of phases, that suggests that pins 1/2 should have green/black or blue/red, and pins 3/4 should have the other pair, right?
That's what I thought based on the wording, but it's wrong.
As a very recent example, I was wiring up a 17HS08-1004S from omc-stepperonline and the wires tested as mentioned above. When I tried to turn the stepper, it'd do nothing but vibrate. In order to get it working, I had to wire it as black, red, green, blue.
