Original-Prusa-i3 VS Voron

I've been effective with OpenSCAD and FreeCAD.

OpenSCAD is good for enclosures: https://github.com/sbambach/MarksEnclosureHelper

and mechanical systems: https://github.com/prusa3d/Original-Prusa-i3

Don't think of it as a programming language; that will hurt you. Think of it as a specification language. That helped me.

Being the printer already assembled and working, I am looking at pg. 12 of the printer manual downloadable from prusa3d.com, chapter 6.3.1 Calibration flow and wizard, showing two different scenario... one for kit and one for assembled printers. Am I correct assuming I can just go through the latter? Also it's not very clear to me if that's the process I have to go through each time I turn the machine on, before attempting any print.

TLDR: replace the adapter-printer if it's worn.

They’re usually bought at https://prusa3d.com

On top of that, people simply don't know what they're doing. For example, the Prusa MK3S+ STL files are licensed under GPLv2, which does not make sense because there is no source (the source files are GPLv3 for some reason). But if you look at the remixes, the majority are licensed under some Creative Commons license end even the Public Domain. All those remixes are mis-licensed because only the GPL is compatible with the GPL.

you are right, but many people have asked for this.... reddit, github.. even on prusa3d.com but they dont care...

The BOM (of sorts) of the MK3S exists here.

No corresponding source for the parts is available? I don't seen an MK4 branch in there, unless they ditched openscad entirely (even then at least STEP files should be provided if it's still Open Hardware).

From prusa3d.com:

Anti-features like this just make me more convinced to get a Voron instead. Open source design, great community, almost infinitely moddable, and at least as capable as the Bambu. You can self-source all the parts or buy kits from various vendors.

However, I say all this as someone that is technically inclined, wants to tinker, and is a fan of the open source. Somebody that wants plug-and-play should definitely look at another printer.

"The original goal of the VORON project, back in 2015, was to create a no-compromise 3D printer that was fun to assemble and a joy to use. It had to be quiet, clean, pretty, and continue to operate 24 hours a day without requiring constant fiddling. In short a true home micro-manufacturing machine without a hefty price tag. It took over a year in development, with every part being redesigned, stress tested and optimized. Shortly after the release a vibrant community formed around the project and continues to grow today. This community is part of what makes VORON such a special experience.

What was once a one-person operation has grown into a small tight-knit group of engineers united under a common design ethos. We're dedicated to creating production-quality printers you can assemble in your kitchen. It's this passion and dedication that drive us to push the boundaries just a little further. We build space shuttles with gardening tools so anyone can have a space shuttle of their own.

You can use the configurator at the site to try and find a size that could work. However, I must warn you that if those are V-slot extrusions you most likely won't be able to reuse them on a Voron: the slot is to wide to hold the MGN9 linear rails correctly.

Might check out their channel on the Voron discord (can find a link at vorondesign.com) and ask if anyone has any pictures.
