Review on BIGTREETECH SKR Mini E3 V3.0 Control Board + TFT35 E3 V3.0.1 Graphic Smart Display Panel Board New Upgrade 3D Printer Parts For Ender 3, Ender3 Pro, Ender 3 V2 by Robert Gomatham

I'm upgrading from the stock 4.2.2 board on my ender 3 pro. This is been the second best mod to my ender 3 pro. The first being the CR touch auto bed leveling accessory. My first print is a noticeably better quality. And it's INCREDIBLY silent.Print quality: Looking back at previous prints, it's absolutely noticeable. Curves are smoother. There's no noticeable ghosting. No weird print artifacts. I've only done a couple prints but I'm impressed. I wish I had installed this before printing some projects for Christmas presents.Noise: It's dead silent. My 4.2.2 board wasn't loud. I couldn't hear it on another floor of my house and even on the same floor it wasn't loud. I wasn't expecting much. It's SILENT. The motors almost never make noise when they move. I'm astonished.Setup: This is the 600 pound gorilla of this board. The first party documentation is functionally non-existent. The pre-compiled firmware didn't work. If you buy this board, you WILL need to build your own Marlin or Klipper firmware. There's a decent amount of documentation on this but I ran into some hiccups still. I've been 3d printing for about a year now, and I'm an IT professional. I'm familiar with code and can make my way around code to edit if I need to. This was definitely a stretch to my knowledge. If you're a beginner, probably go with something a bit more supported. It took about 2 hours to remove the old board and install the new one. And then about 6 hours to fiddle around with, build, and install the firmware to get it able to do everything that I want it to. I'm taking off a star for this because it's just a lot of work. But that's 3D printing.This was a fun, engaging project that stretched my knowledge immensely. Overall, it's well worth the $45. But just know what you're getting into before you get it.
