SKR motherboard features: 1) Adopt high-performance MOSFET tube, better heat dissipation effect; 2) The use of pluggable fuses makes the replacement process easier; 3) Reserve BLTouch interface SERVOS and Probe for easy use of BL Touch; 4) Use the power selection design to separate the USB power supply from the switching power supply, effectively avoiding short circuit Causes the computer's USB port to be burned; 5) The special function interface uses conspicuous pin headers, which greatly reduces the error rate of wiring. 6) Reserved I2C, SPI, WIFI interfaces, convenient for customers to DIY; 7) Reserved closed-loop drive interface, eliminating the trouble of plug-in transfer module; 8) Dual Z-axis interface, eliminating the trouble of external drive expansion module; 9) The thermistor interface is protected by a bile capacitor pressure sensitive resistor to enhance the resistance of the interface; 10) More fan interfaces: 1 digitally controlled fan, 3 normally open fans; 11) External DC5V power module can be plugged in to supply power to TFT screen, BLtouch. Potentiometer Setting Instructions: Turn Potentiometer Clockwise - Reduce Vref to Reduce Drive Current Turn Potentiometer Counterclockwise - Increase Vref to increase drive current If the motherboard provides 12V or 24V, the exact voltage of Vref can be measured. Range of Vref values: Default value: 1V (± 0.2); MAX: 2V; MIN: 0 V;Do not apply excessive force when turning the potentiometer to prevent irreversible damage to the potentiometer. When the potentiometer rotates counterclockwise to its maximum value, it becomes the minimum as it continues to rotate as it is turned clockwise to the minimum. If you keep turning, the maximum value will be displayed.

If you don't like it, you don't know how to use it
Replacing a 3D motherboard is a daunting task even for the experienced. You have to be familiar with rolling your own firmware. If you don't know what Atom of Visual Studio Code is, then do not buy this until you learn some more about how this stuff works. If you buy this thinking you're just going to drop it in as a replacement for your existing board, then you should immediately stop right there.With that said, this board and the TMC2209 drivers are an amazing alternative to the Duet boards. Quality is right up there and the price is significantly less. If you're experienced with Marlin and want a board that will make your printer dead silent (minus the fans, of course) then pick this up.

Great option for super quiet performance!
The media could not be loaded. I recently decided to upgrade my Creality Ender 3 to use the SKR 1.4 with TMC 2209 steppers. (Side note, you will need to find an alternative case to use this on an Ender 3, as the stock case doesn't line up- I found one on Thingiverse).About the upgrade process:If you have never upgraded your main board before, I recommend checking out some 3d printing videos on youtube. Teaching Tech has some good ones. You may need to change connectors and potentially solder wires together in order to upgrade your board depending on your situation. In the case of the Ender 3 main board, it uses 2 pin end stops, and this board uses 3 pin. I created a simple adapter cable. Beyond that, just about everything was a 1-1 connection from the old board to the new one.I cut off one of the pins on the TMC 2209 driver, because I am not using stall guard but instead using the optical endstops. This is explained very well in the BTT SKR 1.3 / 1.4 manual.After you get everything set up and connected, you also need to configure firmware. I am very familiar doing this (having done it on several 3d printers) but many folks struggle more here than the hardware. If you have trouble here, Youtube is also a good resource and check out videos from Chris Riley (TMC2209 install). Chris's Basement. You'll need to make a few changes to the Configuration.h and the Configuration_Adv.h for your specific layout.The performance is really good on this board, and the printer is super quiet as you can see in the video. It's a great upgrade and can be done in a few hours if you know what you are doing.

Great features, not so great documentation
On paper, what's not to like? It's the fastest board BTT has released. It has a dedicated BLTouch port. 2209 stepper drivers are the best Trinamic has to offer right now.Well... For starters, the dedicated BLTouch pins don't work with Marlin. you still have to plug it into the ZMIN port. If you want to use regular endstops instead of the sensorless homing that the 2209s offer, you have to cut the diag pin on the drivers you wish to use endstops on. On the SKR 1.3, you could reconfigure it with jumpers. That's a WAY better experience-- I don't like having to needlessly cut pins on motor drivers. What if I want to switch to sensorless homing later? Then I have to resolder that pin. What a bother.But, the board does work, the steppers are silent, and sensorless homing, if you set the thresholds correctly, does work. It's still a good value, and it's a great upgrade over most stock printer boards you'd find in Creality or other printers.

Monumental waste of time!
I hate myself for buying this board. I have spent at least 100 hours trying to get things running on my printer. ONE PROBLEM AFTER ANOTHER! Definitely an advanced project. It continues to suck up countless hours with very little progress being made. I should't have bought such a new board and stuck with a tried and true ramps 1.4. If time is money to you, stay away!

Excellent kit for a power user
I'll get one thing out of the way right now: if you are NOT an advanced user with experience editing Arduino code (or similar), this is NOT the kit for you. It does not come with an up to date version of Marlin, so you're best served by downloading Marlin 2.x straight from Github and making the required configuration to the firmware yourself. A number of users have done this and posted instructions, so I will no go into details on that here.However, once you have the firmware configured and installed, this is an amazing board. The CPU is fast and produces very smooth and clean prints, there is ample memory for the most advanced Marlin configurations, and the TMC2209 drivers are extremely quiet. With this board, you can enable all of the advanced features such as sensorless homing, BLtouch/bed leveling sensors, power loss recovery (with accessory), linear advance, and many more.This is a board for an experienced 3d printer operator who isn't afraid of getting deep into the firmware to make changes. You will need to have a good understanding of Marlin to make this work well for you; copying someone else's configuration is not likely going to give you good results unless all of your parts and upgrades are exactly the same. It's absolutely worth the time-investment to learn; my prints have never been cleaner.

works great BUT auto-bed leveling is a pain
The board works great and the drivers that it comes with are both super quiet and plug & play ready for UART. Getting the latest vanilla Marlin working was a snap, HOWEVER, setting up bed leveling was a royal pain. This is my first mainboard upgrade on any 3d printer and while the v1.3 guides are applicable to most of the v1.4 setup I've found that setting up auto-bed leveling was very frustrating. I went through 2 different bed leveling products and racked my head for over a week before I realized not only do you have to REVERSE the Z-stop Min pins, but you also have to REVERSE the logic for the probe in your Marlin settings. Once you do that auto-bed leveling works. Would have given this a 5 star rating if it wasn't for that hang up.As for why I gave a 3 star for install, well besides the pin outs being reversed from what the diagram indicates I own an Ender 3 Pro so this is not a drop in replacement like the Mini E3 variant. If you're getting this for any of the Ender products be prepared to print up a new enclosure for the board.

Cheapish for a reason just don't expect the lcd to last
Lcd stopped working the white screen of death after a couple of hour's using quick Google search its quite a common faultToday 27th July the main board died no longer connects to pc USB or octoprint tried reflashing marlin no joyThe mother board main chip gets very hot to the touchOrdered a second board and screen as I have all the wiring set for this board fingers crossed it will last longer than the last one if not I'll be sending it back for refund

best upgrade ever on a geeetech A10M
This is by far the best upgrade I have done, the board has a lot of user support built around it with tons of documentation on the BTT git website so well done BTT for being a true open source manufacturer.ample ports and connectors and easy to follow instructions on all the pins & ports.Would highly recommend to anyone in the £D print community.

Time to upgrade the brains of your printer
Awesome little board! Coupled with some tmc2208 (or any other trinamics) the printer is totally silent! No more twiddling with ceramic screwdriver on tiny pots. Lots of fan headers. Great community support. Can store 8 10x10 meshes for bed levelling. Great price!

great product
used this on my home built 3d printer , works very well lots of nice features.downside , the instructions are not great but there is a lot of info online to help get it up and running.

no instructions ,no support
the contents was looked at carefully unsure whether the firmware was installed ,or updated ,or anything ,having been caught out before with little support ,(hours of YouTube videos )decided to return the product
