The Ender 3 Max is a nice a bridge between the Ender and CR line of printers. I needed a printer with a 300x300 build volume and like the Ender series so the Max came along at perfect time for me. It's a solid, well built printer with a good feature set for the price. I added a bltouch, capricorn tubing and a compiled version of the latest Marlin bugfix 2.0. The latest version of bugfix has an Ender 3 Max config available so that saved a lot of time. I didn't try loading any of the Creality supplied firmware so I can't say how well they work. Cura 4.8 still doesn't have a Max profile but it's not hard to create a new printer or modify an existing one. Overall, I'm quite happy with the Max. I got the larger print volume I needed and was able to stay in the Ender line of printers.
I'm so happy with it! It prints so quietly, the prints are smooth and it's very easy to use. I would highly recommend
This is basically the baseplate and Y axis of the CR10 with a full sized buildplate and carbo base with the frame of the Ender 3. But it works and the price is good. I got excellent results out of box. Only hitch is that there isn't a profile in Cura or Slic3r yet and the Marlin config doesn't yet have examples. But it is basically 4.2.2 board on Ender with big frame.
On;y x and y stepper motors are TMC driven - 2208 I believe, the Extruder and Z axis are A4988, so there is a reduction in noise but not zero noise. The only thing I have slight difficulty with is the filament sensor - if you don't entirely straighten the first piece of filament it is difficult to thread through. Otherwise a good solid printer I believe with give many hours of pleasure
The print quality is impressive, but silent drivers are useless, as as standard fans are even louder than a standard ender 3 easily reaching between 70 and 85db
