BIGTREETECH SKR Mini E3 V3.0 Control Board +TFT35 E3 V3.0.1 Touch Screen Display 32Bit Silent Board Integrated with TMC2209 UART Stepper Driver Compatible with Ender 3/5 Ender 3 Pro/V2 3D Printer

Bought this for my Ender 3 V2 with a 4.22 board. I was a little nervous installing it myself, but it ended up being much easier than I thought. I think the first board was defective (or maybe operator error) but they immediately sent a new board out and returning the other one was painless. Once I got the second one hooked up it worked just fine with the software. It's so quiet compared to the stock board. It loads quickly and I am super happy that the estimated completion time is way more accurate than the OEM board. It's been performing well with no hiccups after updating the build. It was plug and play, but I updated to to the most current version of Marlin.The only thing I didn't think about when I bought this board was adding wifi. If you are thinking about going that route, look up boards that already have it installed, so you don't need an extra component (unless you want it that way). I plan on going wifi soon for the convenience and so my 9 year old can start a print without having to be to close the the printer in case it's hot. So I will have to get a lil pi and program it accordingly with klipper.

Summary: Great motherboard, just make sure you have a connector for you hotend fan if installing in an ender 3 v2Review and experience:I bought this after I had kinda given up on the printer. Beforehand I had a setup where it was a Ender 3 v2 with a cr touch, dragonfly hotend, raspberry pi 4B (for klipper), orbiter v2, and dragonfly hotend. I got this on a Black Friday deal and decided to install it on my printer. I will admit setup was a bit difficult because I had to redo the configuration files in klipper and get all the driver settings correct but after that I have been tuning it and it works wonderfully. I previously had issues with my orbiter v2 with the old creality 4.2.7 board even though I had tuned the vref on it and got the multimeter out to make sure it was correct. But after switching to this board and putting in the driver settings I haven’t had an issue with it since. The only thing I didn’t like about the board is the way the hotend fan gets plugged in but that just was because I had an ender 3 v2 that didn’t have the connector on the fan already. Other than that I would give it a 11/10 because it was easy to set up, easy to use, and overall improved my printer by leaps and bounds.

I had a Ramps 1.3 board on my printer and it was noisey, inconsistant and the offline controls were cumbersome so I installed this one with touchscreen.Nice connections, clear and easy to connect. Small size, it is nice and compact so it mounts easily. I printed a case for it so I can keep a fan running for cooling.Setup and calibration is easy. With the touchscreen, it is fast and simple.Love the board, runs efficiently and stays cool. Good choice.

Like the touch screen but it was not very live adjusting friendly tried for hours to get my baby steps down to a point it would print. And never did get a print out of it. The mother board is hard to configure in marlin which was the only way I could use it because the stock firmware wants you to use the z stop and not the bltouch port but once I got that programed I never could get the hotend fan to work except with the stock firmware. The marlin terminal on the screen never worked when I would stop a print to do an adjustment the screen would sit on a screen saying system busy and never go back to a operating mode. Switched back to the creality 4.2.7 not as many options with it but at least I don't have to be a scientist to compile marlin for it. Well after some trial and error I got it working after using marlin it just takes time to get use to klipper and how to set it up. It works great live the board so I changed my review to 5 stars.

While this board is compatible with the CR10 S5, there are a number of things you should know before buying* If you plan to run klipper, the TFT display is not compatible without a decent amount of additional wiring to your raspberry Pi* When running a BLTouch, the instructions are WRONG. You must attach the "sense" wire to the Z endstop plug (PC2 in Klipper). It will not work in the main IO pins. The rest of the BLTouch wires to connect to the IO slot as the instructions indicate.* You will need to put new connectors/crimps on the end of your BLTouch. One side will get swapped to Dupont connectors, the other to JST connectors.* While it supports dual Z, it uses a single stepper driver so the Z screws cannot be operated independently (You cannot do gantry leveling)* You will need to build a splice cable as there are not enough fan headers for all the fans in the CR10 S5 (You will need to make a split connector for both the fans in the controller case)* The USB & SD slots do not face the correct way in the CR10 S5. You will need to make cutouts in your case to run the USB cable. The USB card can only be accessed by opening the controller case.Now that the bad things are out of the way, here's the good.* This is INSANELY quiet. It is way quieter than my Ender 3 with the Creality brand silent board.* Tons of features and works great with Klipper.* Speed is every bit as good as the stock board (that's mostly limited by the size of the moving bed)
