Bests & Worsts Reviews from Amazon

This printer completely met my expectations. I had a bad first experience in the 3d printing world with the mendelmax2. It was just too finicky to get setup and printing properly. This thing though lives up to the hype. Largely pre-assembled except from the vertical elements. It really is very well thought out. If you have any experience with 3d printers, you'll find this simple. If you're not mechanically or electrically inclined, it will take you longer because you're surely being overly cautious. I got the pro version with the upgraded power supply and the cmagnet build surface/plate. My #1 complaint with my MM2 was bed leveling and print adhesion. It was like voodoo. But this cmagnet plate, printing PLA is a dream. Prints stick to it like glue and when they cool, they literally peel right off. Bed levelling can be a tad frustrating and as many have reported, there is some production issue with a plate that isn't perfectly flat. I suspect that has something to do with the way the y-carriage is attached below and causing a slight bow in the bed plate. I could be wrong, but that's my guess. Regardless of the cause, mine still prints very well with stock parts. Right out of the box. Just level the bed and start printing. I'm still in the tweaking phase but am very happy with the out-of-the-box results so far. As others have mentioned there are a couple of tiny quirks you want to address and print solutions for early on. -The z-axis coupling takes some fiddling to get it lined up right and not binding the leadscrew at the top. -The eccentric nuts that tighten the wheels around the printer need your attention to fully dial it in and remove any wobble. -some kind of filament guide/barrier needs to be printed early to keep the filament from rubbing against the leadscrew and getting grease on the filament. Also print the filament guide arm for attachment to the 2020 extrusion early. -search youtube for teaching tech's calibration video. It's a MUST to get your numbers for your printer and filament. Once you have those, you have a starting point to tweak from. This really is a phenominal printer for less than $300. I'm embarassed to tell you what I spent on it's predecesor which rarely worked right. I'm spending WAY more time printing and tweaking models and then printing some more. I can recommend this printer without hesitation.
