BIGTREETECH SKR Mini E3 V3.0 Upgraded Silent Board Motherboard for Ender 3 Integrated with TMC2209 UART Stepper Motor Driver Based on V2.0 Compatible with Ender 3 Pro/5 3D Printer

Summary: Great motherboard, just make sure you have a connector for you hotend fan if installing in an ender 3 v2 Review 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 have wanted to run more overnight prints, but the noise level on the oem Creality board is obnoxious. This BIGTREETECH SKR Mini E3 V3.0 was a great upgrade. No more high pitch noises, just fan noise while printing. Installation wasn't plug and play due to needing to aquire a connector for one of the fans. The hardest part is getting firmware configured and created. Thankfully there is some help provided by TH3D which makes building it a little easier. My first print after re-leveling the bed is looking great. The noise level is miniscule compared to before. I'm liking this replacement board. I'll be running a print overnight and testing it out further in the coming days. My 3D printer was a stock Ender 3 Pro with silicone bed mounts and a PEI bed sheet. Update: I've had this replacement board installed about a month now. So far everything is working great with my Ender 3 Pro. I have printed several boxes almost non-stop for about 8 consecutive days and everything had been working well. No overheating issues or errors. Having a silent board is worth every penny and I use the printer so much more now.

Execelent choice for klipper upgrades to those old printers that deserve a new life. So far running flawlessly on two printers. The board is really easy to configure, as there are countless configs online to get you started.

Well this works great and have to say, the first one stopped on extruder, not sure why. They sent out a replacement and have no issues since. Excellent board and nice and quite steppers.

I picked up an Ender 3 v2 second hand with CRtouch and easy replacement horned pre-installed. After several successful prints I decided I wanted it to operate bit quieter so I could print while sleeping or working without being bugged by the noise. I picked this up and wired it in. It was 80% functional minus a modification needed for one of the fan controllers to go from raw wires to a 2-pin connector. The big issue is that the firmware is not allowing negative z-axis settings so none of the bed leveling, homing, or z-axis offset or printing will work. I tried installing a new BIN for CR-Touch with no luck on this feature working. Z-Axis goes up and down on positive values but won’t work otherwise. Auto bed level fails on the first step.
