BIGTREETECH SKR 3 Motherboard SKR 2 Upgrade 32bit Silent Control Board Support Klipper/Marlin Compatible with TMC2209 Drivers TFT35 E3 V3.0.1 Screen 3D Printers DIY Mainboard

I absolutely love this board in my ender 3 with dual Z motors. Was going to get another and they disappeared without a trace. What happened?? Not sure. I ordered the SKR 2 instead. Hopefully I like that one just as much.

Purchased this board to go in my ender 5. Followed all directions and was unable to get a working firmware. Located very minimal references for this particular chip. Most support out there is for the 743 chip, not the 723. Marlin from what I could find is not compatible with 723. It could be, but through my hours of rooting around and following tutorials, 723 isnt in the cards. Followed multiple guides to setup klipper to no avail. Many hours wasted on this board. Edit: I struggled with this board for a few days, there is nearly no support for the board anywhere. After mixing and matching a few different tutorials, I was finally able to get this board up and running. As of right now, the board is running and it is much quieter than the stock 5 Plus board. This was a great learning experience though.

Installed this board on a DIY core XY printer Ive been building for a while. So far this works fantastic. I already had some TMC 2226 drivers so Im using those instead of the EZ drivers. Previously I have installed an SKR 1.3 and an SKR 1.4 turbo into my other two printers. This new SKR 3 EZ is the best of all of them so far. The fans are pretty easy to set up. I found the Chris Riley YouTube video on this board most helpful for setting up this board. I referred to Chriss video a lot to get this working. So pretty straightforward and not much different than setting up the other BTT SKR boards. I cant say much about how it prints as Im still getting my printer set up. So far I have been able to get the sensorless homing working and test all the functions and it all seems to be working very well. Ill update on how well it prints after I print some stuff.

used these on my mercury one.1 build on my ender 5 plus worked great

I upgraded my Monoprice Maker Select V2 with this board and some TMC2208s. Not recommended for this printer, the stock MSV2 screen isnt directly compatible (get the LCD bundle), the mounting holes dont quite line up, and you need to dremel a hole in the control box for the USB port. Some of the cables needed connectors attached to fit, but this kit does come with the plugs to fit on. Last but not least, the stepper motors are near silent now! No more constant whining. The loudest part of my setup is now the blower fans, and occasionally the print bed axis when it moves fast.

I love big tree Tech. You get a lot of bang for your buck with their products and theyre always super easy to install. Granted I feel like they do have some issues with bootloaders and quality control at times but overall their products are great. This board was super easy to set up and I love having the CM4 on the actual main board rather than running a separate Raspberry Pi. I dont know if it just seems faster or if it actually is but I love how this machine is running now.
