BIGTREETECH SKR 3 EZ Control Board 32bit New Upgrade Silent Board Support EZ2209/ EZ5160/ EZ2130 Stepper Driver Compatible TFT Series Touch Screen, DIY for Most FDM 3D Printer (with 5PCS EZ2209)

Easy to setup and I was able to fin a lot of information about this board on github.

There is a lot to say about this board as I have been a BTT supporter for awhile with their SKR Mini e3 boards as well as their TFT screens. Since this was not as "plug and play" there were some learning curves, but nothing that was very difficult to figure out. Here are some of my highlights and lowlights from my experience with this boardPros:EZ Drivers:It's in the name. These are literally just plug in and they work. No more moving pins or plugging things in backwards. They go in one way and make driver installation completely fool proof. The TMC2209 drivers do allow for sensor less homing, but I chose not to enable that on this board and just use endstops and firmware limits for my bed size. They are completely silent so you don't have to worry about any noise coming from the printer which is as to be suspected with the TMC2209s. This board also has 5 independent drivers so you can run G34 Auto Align on your dual lead screws which is a gamechanger for leveling and accuracy.Fan Control:3 controllable fans on this board is a great option so you don't always have to have fans running when the printer is idle. All my fans are 24v so there was no need for me to utilize the different voltage but having that option is very welcome!Control Board:32-bit ARM Cortex-M7 board is almost overkill, but that's fine by me. For my needs, it will never have any issues and will process whatever, whenever I need it to.CONSFirmware:If you are not familiar with compiling your own firmware, you will not find precompiled versions for this board as readily available as you may think. I'm sure over time there will be plenty out there but if you are not comfortable creating your own firmware you may want to do a little research or be prepared to learn. This is not as plug and play as the SKR Mini E3 boards.Quality Control:I don't know where to put this one, but the first board I received was clearly a board that was returned by someone. There were no cables, no duck, and multiple drivers were loose in the box. At first, I thought that I had enough cables and ducks so it wasn't a big deal but after wiring the board up, it didn't work whatsoever. I triple checked the pinouts, did my diagnostics and got NOTHING. After going back and forth with customer service to no avail, I just returned it for a new board. The replacement worked perfectly wired the exact same way and it came with all the products I was expecting. Thankfully I bought this on Amazon and could return it. This was concerning since I bought this through BIGTREETECH's Amazon store but I guess they are sending out possibly returned product as new which is concerning.Overall, the board itself is GREAT and I would recommend it to anyone looking to get some additional features and possibly run Klipper, Sensorless Homing, or Dual Z Leads. I can overlook the initial product issue since it was taken care of, but I didn't like that returned product was being shipped for new orders. This needs to be resolved so the same thing doesn't happen in the future. I still am a BTT fan overall because the product speaks for itself at the end of the day!

Very good product

klipper and raspberry pi can't find it can't get marlin to work toovery disappointed want my money back

Mine came with the faster (550mhz) cpu.. The setup easy,.Use "default_envs = STM32H723Vx_btt" in platform.ino rather than "default_envs = STM32H743Vx_btt".use "MOTHERBOARD BOARD_BTT_SKR_V3_0_EZ" and everything works as expected. :-)Works like a charm on my CoreXy Printer . :-)
