Re-assigning the x axis
Can someone please write out exactly what I must add to config to reassign my x axis. I've read everything I could find about it but I cant seem to get it right and can't do it. It's only a couple of words and numbers but can't get it right and I'm trying to finish my ratrig V cast IDEX for the last few days. The duet 2wifi is basically new but I burned the stepper when trying to hook it up to my old printer and didn't notice a washer on the floor and my duet was right on top of it and when I turned it on to test it shorted the stepper don't want to spend a bunch of money on new board if I can reassign the x stepper.

Assuming you have something like below with a spare driver:
M569 P0 S1 ; drive 0 - normal - X M569 P1 S1 ; drive 1 - normal - Y M569 P2 S1 ; drive 2 - normal - Z M569 P3 S1 ; drive 3 - normal - E M569 P4 S1 ; drive 4 - normal - spare M584 X0 Y1 Z2 E3 ; set what motors do what
then you can do this:
M569 P0 S1 ; drive 0 - normal - bad M569 P1 S1 ; drive 1 - normal - Y M569 P2 S1 ; drive 2 - normal - Z M569 P3 S1 ; drive 3 - normal - E M569 P4 S1 ; drive 4 - normal - X M584 X4 Y1 Z2 E3 ; set what motors do what
where 4 replaces 0.
@fcwilt well yeah. But I also have dual z so from what I've been reading I need to reassign it to one of the 40puns where the expansion board would plug in

@milicig in which case you have 3 options.
Buy the external driver expansion board and another driver to drive it.
Buy a duex2 and use that to drive it.
Buy a duex5 and use that to drive it.
Or use a single Z motor and belt to keep the two lead screws in sync.
Or potentially get the driver chip replaced/repaired.
@phaedrux but there is a way to reassign the x to other pins and then use one of those BIGTREETECH stepper drivers and have it working perfect like nothing happened. No-body has read about that? You can use some of the pins where the 40pin expansion cable would go. You loose the ability to add the expansion board but you get your stepper back just with a plug in driver. I have a duet3 also but I'm using that on my blv mgn cube corexy. Or the other way around. The duet 3 on theratrig IDEX and duet 2 on the corexy.
@phaedrux thanks I wrote a guy on there but found a better link explaining how to do it better so I might be able to do it myself with this article on the duet site.
@milicig Yes, using an external stepper is an option. We even make a breakout board that makes it a bit easier.
There's also a guide here: https://duet3d.dozuki.com/Guide/Connecting+External+Drivers/22
Keep in mind that you do lose some functionality with external drivers like being able to set the currents in software, and things of that type.
@phaedrux thanks for this. That's alright if I loose some functionality as long as I can get it to work. The board is almost new not really used and don't have money to just throw it away and buy a new one. I did just get the duet 3 but in using that in another build.
