This mainboard was by far the best upgrade to my Ender 3 Pro (MicroSwiss all-metal hotend is a close second). The TMC 2209 drivers make the steppers so quiet that I sometimes forget it is actually doing something (although there is the fan noise). The added space on the EEPROM was perfect for fitting all the features I wanted into my Marlin build (Linear Advance, Auto-Bed leveling, and Junction Deviation in particular). Not entirely sure why BIGTREETECH only lists 256KB...it is actually 512KB which allows me to compile 'bloaty' stuff (PIDBEDTEMP, M503, boot images, extra menu items for LCD, etc.) into the firmware and not have to worry about saving every last little byte. Installation wasn't difficult, but it was frustrating as Creality hot-glued everything to their stock board. Took a long time to get that stuff off without damaging anything. Came pre-loaded with a recent version of Marlin and was easy to flash to a custom build by simply dropping a 'firmeware.bin' file onto SD card and turning the printer on. A nice feature is that after it updates the firmware, it renames the file to 'firmware.cur' so it does not try to reflash every time you turn the printer on (the bootloader I flashed to my stock board didn't do this). BLTouch & Auto-Bed Leveling I did have some trouble configuring the firmware for ABL using the BLTouch at first. Most guides out there assume you are plugging into the Z-Stop on the board, but this board has the 5-pin header for BLTouch (which was convenient to build a 5-pin DuPont connector right to the board instead of separate 3-pin and 2-pin connectors). In your configuration.h, make sure that #define Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN is commented out and that you are using #define USE_PROBE_FOR_Z_HOMING. One other thing I had to change was #define Z_MIN_PROBE_PIN PC14. PC14 is the Z-endstop pin from the 5-pin header. The pin set to this by default will not work. In configuration_adv.h, PROBE_OFFSET_WIZARD is a really handy menu option to help set the z-probe offset value. There are other minor things you have to change to get ABL to work, but all the guides out there cover that in great detail. The Instruction Manual does include a link to pre-compiled Marlin binaries for this board. I believe from that page the 'firmware-bltouch.bin' would have worked for me using the 5-pin Z-Probe header, however the webpage is unclear and I wanted more control over what features were in my firmware. Would be nice if they supplied the configuration.h and configuration_adv.h files for these builds so that users know what's in them. Extra Stuff I bought the kit with the Mainboard, BLTouch and no touchscreen display. Be aware that the wires for the BLTouch probe are nowhere near long enough to reach your mainboard. You WILL have to do custom wiring or need to buy a BLTouch extension cable (1-meter should be long enough). This kit does NOT come with a bracket for the BLTouch either. I printed one out from Thingiverse and it works great, but if you prefer a metal bracket, you'll have to buy it separate from this. The kit does have appropriate screws/washers/springs to install the BLTouch. It is pretty clear in the description and pictures that it would not come with the bracket or long-enough cabling, however some folks might not notice or realize they need these things and be very disappointed. Overall a great board and an awesome upgrade that would really only be better if the documentation was more specific instead of a few pictures and incoherent sentences. In particular, configuring Marlin for BLTouch using this board's 5-pin header (notably the PC14 pin). Oddly, the BIGTREETECH configuration files specifically for this board on GitHub for Marlin do NOT have the pin defined as PC14. Despite a few challenges, this is still 5-stars all around because this upgrade is not designed for people who like for things to 'just work' or simple plug n' play. Go buy a more expensive printer if that is what you want.

This is a detailed 2 part review please take time to read.... 1.) This board is amazing! Installation was a breeze just recommend to take a before photo of the old board wiring before beginning and then be sure to pay attention to the wiring diagram online from BTT and after a little bit of time compiling the firmware on the card and uploading to new board the printer runs like a dream. so quiet you don't even know its printing all you can hear are the fans cooling. I do recommend watching the video on installing this board and compiling the firmware that's on YouTube by Chris's Basement very helpful. 2.) Now on the back end of things the first board quit working after a few days couldn't get it to reset or work again even after re flashing the firmware. Amazon did replace free of charge and sent another out to me, however it was shipped in its own little box it was NOT placed into an amazon mailer of any kind no bubble mailor no outer box with cushioning there was nothing but a shipping label on the outside so of course the board was damaged in transit and I couldn't even use it. Since this was already a replacement sent out they could not send another one to me just a refund for the purchase price. This was ok however now I was left with no board for my printer and I purchased this board when it was on a one day sale and since the price had already increased again they could only refund the sale amount originally paid and now I must come up out of pocket the difference to re order one more time and hope for the best on the third attempt.

Style: SKR Mini E3 V2.0
This board was a great upgrade for my stock CR-10s. The board itself is small, and it took some time but installing it was simple, just make sure you cable manage. The board allows for my stepper motors to be even quieter and accurate to 0.25 mm.

Pros: 1. If you are planning on going beyond what Creality provides in their printers, this is an excellent base upgrade. It allows many more options than the base board, making modding the printers significantly easier. I was able to plug in the bl-touch without unplugging the z-stop switch. There are many other ports for common upgrades. 2. The replacement of the original board is EASY. Just unplug the wires from the Creality board and plug them into the same place on the SKR board. 3. It is SILENT! I really didn't have a complaint about the noise of the stepper drivers in my original Creality v1.1.4 board, but the drivers on this board make the steppers essentially silent. I had heard people complain about the fans and I chuckled... Now I get their complaint. Cons: 1. If you buy this kit with the BL-Touch, it comes essentially not wired. you have to supply the wires between the short pigtail from the BL-touch and the board. You have to have fairly specific crimping tools to do this (I happen to have them). 'cmon guys, supply a wire for this, it wouldn't cost you virtually anything and it would make this kit much more viable for the average user. I have an issue with the BL-touch working and I blame it on my wires. 2. Firmware Availability. I upgraded a CR-10 not a Ender. Finding firmware that works with the BL-touch and this board was somewhat difficult. the Bigtreetech github site doesn't list it... Perhaps that is just a matter of configuration, but I don't know. It seems that building your own firmware is common, and it is really not that hard, and it is what I ended up doing, but It shouldn't be necessary to do for this upgrade.
