Hello deciding

I would personally splurge for the MK4S, the speed and quality is unmatched, and the MK4S is still phenomenal. Also, you have the option to upgrade it to a Core one later down the line. Rather than a mini for $700, you can get the MK4S kit with free shipping for $800 https://www.printedsolid.com/pro

Is Prusa not offering the semi-assembled XL anymore?

About 6-8 years ago, I worked for a print farm running MK3s, and I built 4 or 5 of them for them in that time. Because even though Prusa was offering fully assembled printers, I made a decent wage assembling them and still came out less expensive building the kits. It was also an excellent education

Is there future of the Original Prusa MK4/S Enclosure a dead end?

You can sell it, there is probably some customer base with mk3 and mk4 that may consider it for right price. I believe for various reasons enclosure for mk4 was really dead end. The Biggest issue is to volume you have to heat up, location of the printed part on the bottom due to printer construction

What’s your go to 3d printer brand? And printer that you have used and have barley any complains about

I have a Prusa MK2 that I can turn on and print like new, if I wanted. It has 28k hours and I've only replaced belts once, and fans due to bearings wearing out. I have three MK3s with more than 15k hours each, one near 20k. Again, only a few fans, one extruder because of my own dumb mistake. My MK4S

Used MK4

Upgrade kits are very well documented, and prusa 24/7 support is very helpful for when things go wrong. I like prusa's philosophy a lot as well. I started with a Mk3 and upgraded it to a mk3.5 last year. When indx comes out, I will move my nextrueder over to it and turn it into a mk4S. So I'm still

MK3 upgrade kit to MK4S more expensive than entire new MK4S?

Actually imho the best way to ugrade the mk3s+ is using a Prusa Minis Buddyboard and Snake-Firmware from Github. Its called "mk3.3". It miss powerloss Recovery, MMU suport, NFC and crashdetection, but comes with a much lower price. The board itself is about 45€ at Prusa. The display, while about 100

“Does the Core One just work” Yes, here’s proof.

The two big pro for me are: That Prusa is open source firmware so you aren't beholden to the whims of the company. Bambu tried to lock down their firmware a few months ago but had to partially backtrack due to community outrage. Still it broke integration with third party slicers iirc. Prusa sells u

MK4S—>Core One Upgrade…Amateur Edition

If you updated from a MK4 or MK4S, you will need a lot of additional parts, so I would recommend to do this only if you consider this project to be worth your money (also consider the opportunity cost concerning other spendings of your money). On the other hand, if the MK4S was originally some older
