@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.

Hm, I don’t think I can quite grasp how much of a difference it would make to have a couple of cm extra in each direction. For my actual planned projects, I know it will be sufficient (except for one, where none of the consumer grade printers would be, and I would need to splice multiple parts somehow). But I also know that the list of planned projects will expand much faster than I am able to plan, design and print…

Hm, in what way have you experienced any problems with this? I understand that it is not fully open source, but as far as I could tell, you can’t go much more open without going with a Voron?

I would love to get the kit, both as a learning experience and a fun project. However, they are not shipping the kits until April/May or something like that, while the assembled printers start shipping in January. I don’t think I want to wait that long.

> 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.
Ah, yeah, I would also have expected their app to be open source.
Are the step files not generated by the slicer?
@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.
Ah, I see! I have much to learn, but looking forward to getting started :)
No, .step file is an exchange format, (think .pdf files), that can be used across different CAD programs to import geometry so you can work on them.
Unlike the common .stl format, a .step file contains a majority of the internal information that was created by original CAD model. While an .stl file is just meshes and nothing else.
PrusaSlicer can use .step files directly to slice. But I’m not sure that other forks/slicers can. I like models in .step file because it’s far easier to open them in whatever 3D CAD software I’m using to make changes to a model to suit my needs. I can do .st’ files, but it’s a pain to work with them.

Prusa has other software than their slicer? What does it do?
@aard most importantly, it notifies me when the printer needs my attention (e.g. change filament). My biggest annoyance (and what I wanted to fix/change) is that their app icon is not a proper vector graphic image, so it doesn't look good in themed Android launchers.
Mobile app, web app, firmware, bootloader…
