SKR Mini E3 V3.0 32Bit Control Board with TMC2209 UART Stepper Driver New Upgrade 3D Printer Silent Board for Ender 3, Ender3 Pro, Ender-3 V2 3D Printer

This is an amazing product light-years better the the original board I had it works fanatically my printer has never worked so good and it's so much quieter... over the moon happy...... more importantly the seller is wonderful I had a slight shipping error (postal system not the seller).... But the seller responded and helped me out almost instantly... wonderful human being I 100% recommend

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.

Easy to update firmware, super quiet. Was it necessary? For me not really, but I bricked my board and needed to replace it. I could have bought the cheaper one, but decided on this one.

Replacement seems a little intimidating at first, but it's really pretty straightforward. It's just a process of unplugging about 694 little plugs from the old board, then re-plugging them back into the new board in the exact same place. There are a bunch of videos on the YouTube to help. Probably the biggest challenge may really be getting those 6-8 little tiny screws in and out of the printer to open the box and remove the old board. Take a drink or stop drinking before starting- whichever steadies your hands. Functionality is incredible. I used to be able to hear my printer from downstairs, now the fans are by far the loudest part of the machine. Going to add some beep tones to the slicer profile so I can tell when it's done. EDIT: on my second or third print, my extruder jammed with PLA mysteriously wadded up around the gear. Pulled it out, cleaned it up, and started printing again. A day later, it happened again. Googling took me to several posts about these boards pumping out too much current to the drive motors, causing overheating. In my case, the extruder motor was getting hot enough to melt the filament as it was pushing it. Learned that you need to lower the drive current to all of the motors once you replace the board. Now everything is cool to the touch. GCODE I used was: M906 X535 Y535 Z535 E640. Just add it to the start commands in your slicer or set in the printer firmware. Recommended.

Ordering this was perfect since I essentially live in my room at the place I currently live. While the Ender 3 Pro isn't SO loud that I couldn't sleep, it was something I was thinking of improving, plus the safety features and upgrade-ability sounded awesome. The first one I ordered had issues and I couldn't get my 3d printer to heat up, it would error out. It seemed like it couldn't regulate the hot end or hot bed. I tried switching around wires but I spent hours on it. Eventually I felt defeated enough to contact them to exchange the item. The replacement they sent was essentially plug and play, and I was extra careful with it to make sure I didn't mess up any of the connection points. It is much quiet and I am excited to start printing with it. Well worth the ~$30, only 4 stars because of the need to exchange it, not a huge deal though and not a deal breaker!
