Good news guys..

I have now altered the config.

As follows

M569 P0 S0 ; Drive goes forwards
M569 P1 S1 ; Drive goes forwards
M569 P2 S0 ; Drive goes forwards
M569 P3 S1 ; Drive goes forwards
M584 X0 Y1 Z4 E3

I have now a functional z axis. 🥳
But I have a new problem.
I have 2 y axis stepper motors.
Since I have change this config I have only 1 working.

Any suggestions please
Do I change the m584 part so it's y2?
Or is that something different?

@peter247
My drives
Same as your except my m584
My reads

M584 x0 y1:3 z2; apply drive mapping to axis

undefined

@peter247 ok that diagram is brilliant thanks.
I have z2 available
And e1 available.
Would the z2 also be affected by my malfunctioning z chip?

Should I just go straight to e1?

undefined

@craigylad86 and you want me to change the commands to controle z to go through port e0 and use that as a route.
So I have to then reconfigure a section of the program.

undefined

@peter247 ok so I have limited knowledge on computers and part names I'm learning as I go along.
I'm assuming e0 or e1 to be other ports.
Is this the one directly underneath the z on the board?
Or the one at the end of the row?

@peter247
All the axis failed to home. So i opened the program.
The only reconfigure I have done is to open all axis from not having to home before activity. As described when setting up and fault finding.

Think it's m1 to a m0. Or similar can't recal without looking.

If the z on the board is dead
What can I do?

Is it a board replacement situation?

@peter247
that's what I have concluded.
Z on the board does not move X motor at all, not even a juder.
In fact there is no resistance in the motor, I can manually move the axis.
This is true when the board z is connected to eather X or z motor.

undefined

@peter247
Yes..
So I swapped the Z and X axis on the board.
This provide the the opposite results as the issue I was having.
X on the board would control Z motor
Z on the board would not move X motor

undefined

@peter247 thank you Peter. To check the motor i have connected the X axis to the z motor and selected the X axis on the dashboard.
Doing this makes the z motor work as it's commanded

Hi first time post.
I have been using a duet 2 on an open build CNC router.
I have had this for a few years now and over that time I have had and fixed a few issue by trial and error and guidance from forums such as this.
But I'm really stuck on this one.
I have hunches as to what it may be maybe someone can confirm...

The z axis started to play up by missing some steps and eventually juddering up down and in opposite directions as I was controling.

I have since tested all axis with home deactivated all but z worked.
I have now tested the actual Moto by swapping bthe connection from X axis to z motor.
This has confirmed that the Motor is in good working order..

I have checked the duet board and all seems to look ok. No fuses blown or loose cables.

I'm now beginning to think it may be the board itself.

Is there anything else I can test to confirm this.

All help will be kindly received.
Thank you undefined
