Model: MK4-KIT-ORG-PEI
This is a pretty awesome little printer. It took me 3 days working a couple hours each night. I accidentally mixed the x and y connections on the mother board so it wouldn't calibrate when I first fired it up. After reviewing the books that came with it and realizing that the x axis is the left right of the machine calibrated with no problems. Getting the prusaconnect and prusa link took a little to get connected but works like a dream after slowing down. The instructions were thorough and well written. I wanted to verify some pieces that came with it were the actual pieces I was supposed to use so I used the online chat. It took a few minutes of waiting before I got some help but once I did it was quick. Prusa slicer is pretty straight forward and has great features to get started and has different levels of set up from beginner to expert that allows you to customize it as you learn the program and become more familiar with 3d printing. I would by this machine again and I had fun putting it together but it does take time and patience.

When I bought this I didn't realize it was a kit and that I would be basically building the entire thing myself. It took me almost a week to build it by working on assembling it a few hours each night after I got home from work. When I finally booted it up it got hung up on a wiring self test so I contacted Prusa's help chat line and the person I was talking to diagnosed the issue in under 30 seconds. I swapped where two wires were plugged into the circuit board for the extruder and I was ready for action. This is my first 3D printer and I went with this model because it has a number of preset settings and automation that make it easier for a first timer to get into the hobby. The good thing about Prusa is that they have good support for their printers and provide updates for their legacy printers making them upgradeable over time to increase functionality and extend their capabilities. The build quality of the printer seems pretty good and Prusa makes a lot of the plastic parts on this printer from other 3D printers and also offers files online for free if you ever need to print your own replacement. The user interface is pretty good with a full color display that has easy to navigate menus and good feedback while something is printing. I haven't had many issues with failed prints but when I did it was obvious that there was either a filament issue, a part/model design issue, or something wrong with the way I set up the print in the free slicing software. I've printed probably a half dozen brands of filament so far in many different colors and had no issues with extruding or filament jams. If you have a bit of extra money to lay down (there are other printers available for less out there) you won't be disappointed in this printer. Prusa makes solid printers that have very long life span and I expect this printer to live up to the name. I've not had to do any maintenance on this printer except for cleaning off the outside of the extruder hot end once.

Works great and buying this printer as a kit did save some money but note that I found it a challenging assembly. I have built quite a few computers but this was more difficult. At the end I wondered whether the saving was worth the frustration. Getting the tension right on drive belts takes much more fussing around than just screwing in a board or a drive. In several places some assembly required awkward reaching around the printer. The step by step directions were good and the comments inserted into the guide by other users were sometimes essential - when the wording in the online guide was not as clear as it could be. Clever idea to include such comments. I added my own when I thought I could contribute. I also used their online 24/7 chat to get help a couple of times when I could not figure out why I could not get the printer to pass a calibration test. It turned out that i had not noticed that one of bearings had slipped out of position. Only thing negative I can think of is that the power cord did not fit very well and could become loose - which would turn the printer off! Fortunately, I had a compatible cord from an old computer and it fits perfectly. I guess I could have tried filing their plug down so it would fit better but easier to just swap cables. I have now printed a number of things starting with the easy to use PLA filament. My first try with the TPU (FLEX) filament was not so good but they do warn you of possible difficulties with that kind of filament.

This is a great product. I would suggest to be very patient and carefully read assembly instructions if you get the kit. The belt tuning (tension) app didn't work for me, but it's not necessary.
