But definitely find out beforehand whether there were any security gaps or anything else. I followed the whole thing at the beginning of the tox protocol and the clients were not yet fully developed. But since I couldn’t get people away from WA, I forgot about it over time. So I can’t say anything about the security.
I know session… well i have read about it… Didnt test it because i would fail at the same point like with tox.

Yes, the upgrades are really not cheap and also cause problems with each other. With the Enclosure + MMU3, the bracket supplied for the buffer plates does not fit into the enclosure. When upgrading from the mk4 to the mk4s, the LCD holder no longer fits at the front of the enclosure and other small things like that, which are quite annoying.
Before I bought the MK4, I also thought long and hard about the brand, especially as only OSS brands came into question for me. I quickly decided on Prusa and then had to think about which one (resin was out of the question because of my cats). I initially had my eye on the HT90 and the xl with 5 extruders before deciding on the mk4. Regarding the price, however,
I said to myself from the start “I don’t care, I’m supporting other future oss developments” and the fact that it is produced in a neighboring country was also a point in its favor. I only went for the mk4 because I thought I would have too many problems with the xl or even the ht90 as a first 3d printer.
Oh yes, the enclosure itself also causes problems because you have to place a plate under the enclosure and under the printer. So that the printer does not start to amplify its own vibrations with the sheet metal of the enclosure but stands on a stable base.
But damn im so hapoy with my choices
Troubleshooting after upgrading from mk4 mmu3 to mk4s mmu3 took well over a week despite help from the Prusa forum and support and in that time I had disassembled and reassembled it several times. In the end it was quite trivial and with the help of additional tools (screw clamp to firmly fix the stepper motor of the y-axis for mounting) quickly fixed. Knowing the localization and the interaction of everything with each other would have helped me a lot and certainly saved time. But I don’t even want to deny that you have to be prepared for several hours and several hours of frustration. Instead, you have to follow the planned and most important steps with the exact number of haribo gummy bears and place them correctly on your tongue and get to the process of enjoying them as quickly as possible. If you also opt for a prebuilt, you could also use the core one
I can only advise every first-time buyer not to choose a prebuilt but to assemble it themselves in order to learn everything directly and gain experience.
I bought the mk4 prebuild as my first 3d printer with enclodure and it worked wonderfully. Except for problems at the beginning due to wet filament etc. but it’s not due to the printer itself. Then I installed the MMU3 later when it was available.
After that I had slight problems,
especially first layer problems, which I was able to fix. then the release of the mk4s so I ordered and installed the upgrade. Initially had massive problems which I would not have had if I had assembled the printer myself and had experience.
The troubleshooting was unnecessarily time-consuming as I had practically disassembled and reassembled the printer but was still successful. At some point (after several successful start-ups and printers) I started up the printer and wanted to print something. Since it had always run smoothly before and never had any really bad problems,
I sat at the PC with headphones on until I looked at the printer and saw that it wanted to become a CNC. Printing plate damaged but still usable, nozzle damaged but could be repaired, heater and thermistor destroyed.
The support was very cooperative but of course I got the heater and thermistor replaced as they are not wearing parts.
I am still extremely happy and can only warmly recommend prusa
The problem is people’s stinginess. They want to save money and buy from China. The manufacturers help themselves to the OSS community but do not contribute anything - on the contrary, the manufacturers undercut the OSS alternatives enormously. They have no development costs or anything else to compensate. So that the OSS solutions do not finance the development for other companies and push themselves out of the market, the only option is to lock it in. It’s the people who want to get into an expensive hobby on the cheap.
Edit: example about developing stats.
PrusaSlicer
PrusaSlicer is our own open-source in-house developed slicer software. The PrusaSlicer team consists of 13 full time developers. As of January 2024, we spent a total of 145,720 work hours developing PrusaSlicer (that’s over 16 years of non-stop work by one developer). While only about 10% of the original code remains, we are still extremely proud that PrusaSlicer is originally based on the open-source project Slic3r by Alessandro Ranellucci. Each of the source files has a short header with the list of all contributors. We believe this is the right way to acknowledge whose shoulders we’re standing upon.
PrusaSlicer is a completely free, feature-rich, frequently updated tool that contains everything you need to export the perfect G-code for your 3D printer. Today, the PrusaSlicer code powers most slicers on the market.
Can recommend ventoy. Then simply put the iso’s from the main distributions with different DE’s on the stick
