I think I want to build a Voron

Hi!

So I think I want to build a Voron (2.4 350mm). I made a lot of research but to fill in the last gaps and to validate if I am on the right track I thought I would post here.

My desire is to have one last printer I have that I can mod and upgrade to my hearts desire (toolchanger some day?). But that also is able to output a (functional) print when I need it to.

Currently I own a Snapmaker 2.0, which is an OK machine. It prints PLA and PETG well, but all the automatic stuff (bed leveling etc.) does not work well so I am doing that manually. Also forget about ASA or ABS. What pisses me off is that it is so unreliable and I have to constantly recalibrate something. I don't mind tweaking and calibrating, but I want something that is reliable after setting it up. Which is my first question: Can I expect a voron to work reliable for a long time as long as I do not change something substantially after I dialed it in?

From what I gather I would be best off buying a voron Kit. Currently eyeing a LDO Rev D kit or maybe a Rev C if I can get it substantially cheaper. Would that be a good starting point? What compromises does the Formbot kit have which seems to be cheaper? The build process should take between 30 and 40 hours, is this still accurate? Is the build structured in a way I can work on it say like 2 hours a day and then continue the next day? Or is it necessary to work on it for longer stretches?

As I am unable to print ABS yet, there seems to be vendors selling the ABS parts. There seem to be functional and non-functional parts. What am I missing when only getting the functional ones?

I already know that I want to mod it (which kind of is a bit of a point for me on getting a voron). There a few things I would like to have quite from the start. Like an eddi probe, camera, exhaust with filter, etc. Should I built the machine and then mod this stuff in or should I build it from the ground up with the modification in mind? Especially as this would be my first build. What would you recommend?

Thank you!
