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
