Driver numbers

Can someone confirm that the driver numbers for a Duet with a Duex4 are as follows. 0,1,2,3, E0, E1 on the Duet. What are the driver numbers of the DueX4 E1,E2,E3,E4? Can someone give me an example of the M584 code for X,(2)Y,Z and 3 extruders please? And will this be the same for the Duetwifi and a DueX2?

I think here you will find answers to all your questions:

The extruder numbers on DueX4 are 2,3,4,5, but they are placed not at this order on the board. Just follow the link above...

Driver numbers 0-9 (as used in M584 commands) are always respectively X Y Z E0 E1 E2 E3 E4 E5 E6. The link in the previous post will tell you the naming of the motor connectors on the Due X4, which depends on whether it is connected to a Duet 0.6 or 0.8.5.

Question on the other commands when you have mapped drivers.

I want to map drive 2 (Z) and 4 (E1) to the Z axis. (M584 X0 Y1 Z2:4).
With the M906, to set the current for drive 4, I would do something like M906 E600:1000 where the motor on the extruder would get 600ma (E0) and the extra motor on Z (E1) would get 1000ma.

What about the other commands like M201 (acceleration), M203 (max speed), M566 (max jerk). Do I use the same E<0>:<1> format or does the Z value apply to all mapped drivers?

In your M584 command you should also specify the extruder drive mapping, otherwise you can end up with a drive mapped to both an axis and an extruder. So your example should be:

M584 X0 Y1 Z2:4 E3:5:6:7:8:9

After that, all the other commands including the ones you mention will take the mapping into account. For example, M906 Z1000 will set both Z motors to 1000mA.

I changed my M584 line to what you suggested and the Z axis stopped working. I found the values 7, 8, or 9 causes the problem. I am running 1.16 on 0.8.5 if that makes any difference.

So use E3 in your M584 command and leave out drivers 5 to 9.

That is what I did. Actually added 3:5:6. Just wanting to let you know what was happening. Based on your message, it sounded like you didn't expect that to happen.

No , I didn't. I can understand that driver 9 might cause problems because it doesn't exist on your boards. But I would expect driver numbers 7 and 8 to work.
