@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.

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.
