I bought the Cr-X pro and initially I had a faulty mainboard which caused the motors to not push filament through the nozzle and instead they just went backwards a bit then forwards a bit and so on. I asked the support about it and after a while they told me it must be an issue with the mainboard and sent me a replacement. From then on I was able to print. Now for the actual review, because I am sure that this is mostly an isolated case and you will likely not experience this:

I am giving this printer 5 out of 5 stars because it prints perfectly. You set the distance for the automatic bed leveling once and then you're set to go. I haven't head filament jams once, my models come out perfecly with barely even visible layer lines even at high print speeds. The multi material printing is amazing and I especially had fun printing pla and pva together for some soluable supports. It had no issue with this and once again the prints were perfect. It's a really sturdy machine and it's basically plug and play.

Here are my retraction settings to eliminate stringing and oozing:
Retraction Distance: 6.5mm
Retraction Speed: 25mm/s

I am using Cura as my slicer so if you use something else you might need different setting. I would definitely recommend this printer and I hope you'll have as much fun with it as I'm having.

The auto leveling is such an amazing feature for this absolute behemoth of a printer, and the ability to switch between two colors or a different material is going to make all the difference when i comes to the things I intend to print. Setup took maybe 15 minutes, and after a bit of manual leveling from being wary of claims of auto leveling, the calibration cube I printed came out flawless. You're gonna want some massive desk space, obviously, but I've been waiting for a printer like this for /years/. This printer is so freakin' quiet, I was on a Discord call with friends, and with the printer maybe 2 feet away from my setup, they had no idea it was running.
