BIGTREETECHSKR Mini E3 V2.0 Control Board 32-Bit New Upgrade for Creality Ender 3, with TFT35 E3 V3.0 Graphic Smart Display Controller Board

I recently reviewed this item but couldn’t figure out how to find/edit that review.I was having problems connecting via WiFi. I have since resolved the issue. The problem was unrelated to the CB2. It is functioning well now.

Absolutely love this board. Incredibly versatile, incredibly powerful. I have this set up with a CB1 and 2209s, everything works great. The manual does a good job at pretty much covering everything, albeit, not phrased the best. Nonetheless, super flexible board for endless possibilities. Love all of the fan controls, stepper driver options, UART mode, DIAG for sensorless, USB, ethernet, etc etc. It truly covers everything for a potentially awesome and big build.I see some reviews talking about "I thought this would include grub screws", or "Doesn't run the printer on USBC power", and - cmon people, it's a controller board. It includes JST connectors, which I wasn't expecting, so that's awesome. And USB C power? I understand a laptop, but you're running 24v heaters and motors, controller, etc, how would this work over USBC? There's no where they mention you can RUN this board with USBC. Like people, do a little digging!Yes, you can use USBC to program and config, it won't power fans, motors, heaters, etc, it's enough power to program things before setting things up. And that makes sense.Regardless, great board, I've been very excited about using it, and it's been fine configuring and optimizing things for my build. New found love for BigTreeTech

Running Klipper along with Manta M8P on a custom 3D printer. Works nicely so far. I will get another one for my new printer project as well.

I put this board in my original Ender 3 and started printing right away. My 3 or 4 year old Ender 3 worked great until I put it away 3 years ago. When I pulled it out of the closet recently it wouldn't print anything. It would just restart when I told it to print. So I bought this board because it works and it already has the Marlin firmware installed on it. I just wanted the printer to work again so I can print parts for my FPV drones.This board has exceeded my expectations. I never noticed how loud the Ender 3 was while printing until I installed this board. The loudest thing on my printer now is the fan for the power supply. I cannot hear it running other than the power supply fan. That's amazing to me.I did a quick bed level on the printer and started printing right away. I have printed 10 parts so far with this board and have not had a single failed print. The OEM board failed prints maybe 10% of the time. I've been printing with PLA and TPU and everything is working out great so far. The prints look great. This board is definitely worth the money. I only bought the board, so I'm using the original Ender 3 LCD screen. I will be getting the touch screen to add to my printer.

After installing this board the parts fan did not work. I was sent a replacement. The replacement was obviously used not in an antistatic bag, no cable or jumpers, and the heat sinks were already mounted with an extra stuck on for good measure (I guess.) This board was dead. They were willing to refund me but they would not send another board. There are many choices of boards out there, look at the choices before Dealing with BTT. There is no excuse for sending out a used board that obviously was untested.

have these on 3 Ender3 Pros, love the upgraded interface, makes working with the printer much easier

I used this to replace a dead creality cr-10 main board, it works prefect with Marlin firmware. No more noise with this board vs the stock board.

It's a BTT product. All the corners that could be cut were cut, as is the tradition with BTT stuff.An Orange Pi or Banana Pi is a better bang for the buck performance wise.Also, when I asked some pointed questions about the pre-baked Armbian install to Customer Support, I got hand waving and vague explanations that didn't address the issue...as is the tradition with BTT stuff.So, I considered this a waste of time and money and promptly binned it...as is the tradition with BTT stuff.
