Hello everyone,
First a few words about me. My first 3D Printer was a Cetus. Which I modified with a duet maestro. Now I’m looking for a bigger more „advanced“ printer.
I’m considering to build a new printer. It should be a reliable model and it would be nice if there is an option to print at least two materials for example PLA and PVA.
I’m not sure yet if I go for an IDEX or CoreXY. If I go for a CoreXY is there a recommendation for Chimera, MMU or an other mulltimaterial solution? Maybe you have some other inputs/opinions for me 
Right now I prefer an IDEX and consider something similar to this project on thingiverse.

Maybe I change the size of the printbed (around 220x220) because I don’t really need a bigger printer and I have a really good 320w powersupply.
I already own a duet maestro and how I get it so far, with the steeper extension board it should be possible to build an IDEX. My concern is the Z-probe for the Nozzles. Do I understand it right, on the maestro I can run only one z-probe?
Is there a nice solution for that? Does anybody have a suggestion how to solve this?
If I don’t go for the IDEX I probably would go for a hypercube evo with linear rails.
My next question is about the stepper motors. Can someone give a recommendation for the motors? It would be nice if the motors have 0.9 degrees.
Thanks in advance, I know these are a lot of questions…
