Suggestion IDEX or CoreXY with Duet Maestro

2rad

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…

For multi material I guess this is the ideal solution atm. E3d Toolchanger All the files are on their github if you prefer building it yourself instead of buying. E3d Github.

A tip would be to consider what kind of material you want to print, like do you need an enclosure and how easy is that to incorporate for the design.

Consider the importance of print speed, a hypercube with a chimera will require lower accelerations, since the print head will be heavier.

have a look at the blv cube.

I believe IDEX printers use only one Z probe. The two carriages run on the same X rail and print on the same bed, so mapping the bed surface and X axis sag for one print carriage should be sufficient. However, if you are not using filament monitors then the E0 and E1 endstop inputs are free and could be used to connect additional Z probes, although not a BLTouch.

You could also use FSR/piezo underbed sensors as a single z probe for an arbitrary number of tools.
