Expanding Duet 2 Wifi with a 6th stepper driver for Triple-Z

Philn

Hello everyone,

Following my previous post, I decided to use one of my two Duets (2 Wifi) to build a CoreXY printer with a triple-z set-up.

Which means I am going to need to add a 6th driver.

I just finished reading:
https://duet3d.dozuki.com/Wiki/Using_external_stepper_motor_drivers

And got some questions:

Can I use the 5 on-board drivers for Z-Z-Z+X+Y and use the additional 6th driver for the extruder? (my goal with this is, all 5 axis movements will end up using the same driver model)
Can I use a TMC2209 as the extruder driver or would you recommend another type, say 2100 or even DRV8825? (I got TMC2209 and a DRV at hand, so would make it simpler)
I admit, that article went a bit over my head. Are there any gotcha's or something you'd in particular advise me to pay attention to?

I have ordered a break out board, the same in the article:

Thank you for your help

P.S. I apologise if General Discussion is not the right place for this thread. I thought about posting under Duet Hardware but since the expansion will consist of external hardware, I wasn't too sure.

Yes that makes sense.

You can use whichever external driver you wish provided it will interface with your adapter board and will accept a step/dir/enable signal.
