@peter247
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

@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?

@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.

@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.

@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
