@bluewing I am sharing my personal experience with the MK4S, since I went down from a 256^3 printer.

Belt tensioning on the MK4S Kit was a pain to do, so I am curious how belt tensioning for a core kit will go. I hope they give a better solution than the tuning app, as tensioning belts for a core xy is noticeably harder.

Neither of these are blockers anyway, like I said, I am happy with my MK4S.

@cyberwolfie so what I mean is files that I can open on FreeCAD and can be modified to create my custom parts (step files), rather than importing an STL, which leads to worse results / more difficult to modify.

This doesn't affect me directly much, but it does affect the community as a whole, and it's a step (heh) back from previous printers that do have the step files available.

RE: Open-Source

in what way have you experienced any problems with this?

For example, and I know is very niche, but I wanted to fix an issue with their app (I am an app dev), to discover that it isn't FOSS like the slicer.

Also as a CAD aficionado, I would love to get the actual step files and not just STLs.

But don't get me wrong, none of these was a blocker for me to get a MK4S.

I am also not sure if I will upgrade to CORE, but that's another story.

@cyberwolfie I am happy MK4S owner and would recommend the CORE, but some considerations:

Print volume IS small. Not having at least 250x250 x/y has been a step back from my previous printer.
The platform is less open than I wished (or, better said, than they make us believe).
I'd recommend getting the kit so you will get to know the printer better. However, CORE's build process difficulty is yet to be seen. I built my own MK4S and it was a fun weekend project.
