SKR Mini E3

The BIGTREETECH SKR Mini E3 V3.0 control board has completely transformed my Ender 3 Printer, earning a well-deserved 5-star rating. This upgrade has made my 3D printer nearly silent, vastly improving the printing experience. Installation was a breeze, which is a huge plus for someone who appreciates straightforward upgrades. The board fit perfectly, and the instructions provided were clear and easy to follow. I was up and running in no time, and the difference in noise level was immediately noticeable. The use of STMicroelectronics' latest G0 series main control chip ensures efficient and powerful performance. This, combined with the TMC2209 UART stepper driver, contributes significantly to the reduction of noise, making long print jobs far less intrusive than before. The addition of three CNC fans for increased heat dissipation is a thoughtful feature. It keeps the printer temperature down during long operations, ensuring consistent performance and longevity of the board. The redesigned drive heat sink further enhances this by improving heat dissipation capacity, which is crucial for maintaining optimal performance. The upgrade from Mini USB to Micro USB B for the PC communication interface is a welcome change. It's more adaptable and fits better with the cables I already have, making it easier to connect the printer to my computer. The option to supply power directly to peripherals via the SPI output port is another highlight. It offers flexibility in powering external SPI sensors, providing both +3.3V and +5V options. This feature simplifies the setup for additional components, making this board not just a silent upgrade but also a versatile one. In conclusion, the BIGTREETECH SKR Mini E3 V3.0 is a fantastic upgrade for the Ender 3 series printers. It not only significantly reduces noise but also improves performance and usability. The easy installation process and the thoughtful design improvements make this control board a must-have for any Ender 3, Ender 3 Pro, or Ender-3 V2 owner looking to enhance their 3D printing experience.

I initially bought this board for an Anet A6. This is a board that isn't designed as a drop in replacement for anything besides a Creality printer, but I wanted to make it work. It didn't take long to get set up. Everything went together easily- connectors were clearly labeled and have a reasonable amount of documentation with it. Only thing I had to adjust were thermistor and endstop connectors, which involve cutting down from a 3-prong connector to a 2-prong. About 10 minutes later, they were all adjusted. From there, I just had to swap wires around for the fans to get the polarity correct. Once I was in Klipper config, config was straight forward. Klipper and Marlin both have example config files you can copy over to your main config file, where you can adjust them to fit your printer best afterwards. I had a failure shortly after getting the first board, and had another one sent out. It worked so well that I bought another one as soon as I bought a second printer, a CR-10 Mini. That was plug and play, as the SKR E3 V3 was designed for Creality printers. I didn't even try the printer with the OEM board. Shortly after, I bought another one for an Ender 3 V2 I had just bought. Same deal, great performance, plug and play, yada yada. TMC2209 drivers are extremely high quality for consumer line printers. You can't hear the stepper motors. 32-bit controllers work great when running Marlin, or any other firmware that piles calculation burden on the board. Even on Klipper, where calculations are run on an external device, you can still enjoy great board support and quiet driver operation. Next printer I buy, I'll buy another SKR board. They really are great. Paired with a BTT TFT35, you get an external touchscreen GUI (after some troubleshooting and configuration). That's a lot of fun to play with. Not compatible with Klipper, everybody. If you're looking for an aftermarket board, most BTT boards will suit you well. Nothing, however, can beat the support and community around the SKR E3 V3.

Great. Slotted in nicely, but was *not* plug and play. You need to use duponts or create your own plug for one of the printer parts, and the silkscreen is on the bottom, like for indicating polarity, and that's just very annoying, when everything plugs in from up top and the board is assumed screwed down while installing the wires. Tip: Needs to be flashed via SD card firmware *before* it will do anything. It ships with nothing, not even a USB device. Easy to do, but annoying that it wasn't preflashed with at least a USB serial connection.

I used this board to rebuild my Ender 3 and turn it into a next gen Core XY printer. The setup was easy. The wiring matched the old Ender 3 motors etc. Everything runs well and very quiet. This board is way better than the original and I've had no problem switching to Klipper. Definitely easy to recommend this board.

Super excited to get this as a replacement board, but found out very quickly that even though the board is Klipper compatible, you can't set it up to work with the Sonic Pad. Very disappointing. I didn't take off any stars because I'm not sure if the fault lies with BTT or Creality, but either way, I can't use it.

If you thought that Creality products can be hard to install you haven't seen anything yet! What could have been a simple plug-play board swap was made a nightmare in a fashion which seems intentional. One of the worse things about this product and company is trying to get tech support. After you verify your email address you have to fill out a large extensive form only to be greeted with a first: their support staff only reads Chinese! They actually say to write your request, translate it to Chinese, then translate it back to English to see what it says before submitting the support request! Forget about getting a even the most simple answer to anything unless you read and write Chinese, or happen to have a Chinese-to-English and English to Chinese translator - and are willing to jump through hoops. BIGTREETECH should not be selling products in a country they are unable to communicate with. We found a bag full of problems they could have easily avoided with valid documentation; which (of course) is NOT included with the board. Almost too many problems to count, starting with no USB cable included as description says. The board comes with a little yellow duck squeaky - but zero documentation and no USB cable. Google found the user manual, which is very badly written, and in some places shows a connector layout which does not match the board. Easy example: the board has three FAN# sockets - but doesn't bother to tell you which one each device uses; like the fan for the hothead, fan for the system board, etc. And where the Ender 3 Pro has screw-down terminals for the system fan, this board has a socket instead but no connector to use it. So you have to create a custom cable of your own?!?! Then trying to hook up their BL-Touch leveler is another dice roll - in one place they say you have to add a jumper to the board and use two different sockets - one 2 wire and one 3 wire - but two pages later says to use an entirely different single 5-pin socket. And the leveler cannot stay attached unless you glue it in place because either the device pins or the socket pins are unable to hold the connector. Then you find that the SD card slot is completely non-functional; which might be why they claimed there was a (nonexistent) USB cable included? Then you have to try and find firmware for the board; which would not load at all. After a few hours of fruitless work and never even getting the device to boot we gave up and had no recourse but to return the product to Amazon. We are used to poor or little documentation for Chinese products but it is absurd to expect a customer to do a translation dance or read and write Chinese in order to get even the most basic technical support; which of course is required since they do not include any documentation. Not a chance we would ever buy another BIGTREETECH product unless we really wanted to be exploited and end up with a completely non-functional device. DON'T DO IT!!!

This board is a winner. I originally purchased this to replace the board in my makerbot/flashforge clone but it turned into a project of nightmare to rewire and make work, not because of the board but because of the terrible design of the printer. I ended up getting a used End 3 pro and swapped the controller out for this little beast, plugged everything up and flashed Marlin and she has been running great since. The installation into the Ender was easy as it can be basically just plug and go. The controller is fast and although there is some electronic noise when using this it barely noticeable way quieter than the printer itself. The board is fully functional for any of the bed slinger printers but you probably want to get a bigger board if you have a more advanced setup or are wanting to add more than 4 stepper motors to you machine. The size is relatively compact and the integrated heatsink is a nice touch both functionally and how it looks. Would recommend I also own the V2.0 of the board so I would recommend this line of product.

The board works, is quiet, and all that good stuff, but... First, in order to work with a BLTouch leveller, a patch has to be installed (search "bigtreetech firmware"--it's on github). There are no instructions on that page, nothing to tell you that the bltouch and bltouch-for-z-homing files are complete replacements for the factory firmware and not just cumulative patches. I installed them in the wrong order so Z homing didn't work. Installing the homing patch all by itself made things play. Second, initially, I opened a ticket with BigTreeTech about the Z-axis failure. Their response said nothing about the replacement vs patch issue and after one response they seem to have abandoned the ticket. I discovered the fix just by noting that all three firmware files are about the same size and concluded that mere patches shouldn't be as big as the whole thing. Third, the board won't work with a 32Gb SD RAM. My first set of firmware installations were done with an old 8Gb RAM. Just randomly, the second time I used an 32Gb RAM and got nothing but "SD fail" messages from the board. (Found that from a Brave browser search...) Fourth, one of the fan connectors in the original Ender control board are screw-down like the heater connectors. On the BigTree board they're standard 2-pin JST connectors. You have to add the JST connector yourself, which is a bit of a pain. (It's not clear in any documentation if all three fan connectors are always-on, which you might need for the board-cooling fan, or controlled, which you might need for the extruder fans.)

I used this board for my ender 3 pro .. I flashed marin on it and it used to work fine printing whatever i wanted until i turned it on one day and it wasnt working .. I confirmed that it was the motherboard because I replaced it with the original board and it worked.

Excelente mejora para la Ender 3v2 Neo, es necesario el cable adicional para la pantalla.

Silent and powerful! Huge upgrade for my ender 5 plus paired with a raspberry pi for remote UI. Great quality and well supported firmware even if it can be a bit confusing to find 😂

Overall I am pleased with this controller and I did a lot of research to decide on this board. You must know that although this board has dual Z connectors, THEY ARE NOT CONTROLLED INDEPENDENTLY by TMC drivers, they are wired in parallel for convenience only. This board has only 4 stepper drivers, not 5. I knew this before I bought the board, but I didn't want to spend nearly twice the amount for an BTT 5 driver board, at least not for my Ender-3 MAX...with dual-Z, maybe for the next 3D printer. Also, I found that the schematics, drawings and documentation show the 24V supply in and supply out for bed heater and hot-end REVERSED!!!! I tried to contact tech support on this but their ticket system doesn't work at all... not happy about that either. In any case, if you follow the wiring of your original Creality board, you'll be fine. The underside silkscreen for the controller does show the correct polarity for 24VIN... Could it be too much to ask to mark the connectors with + and - and/or RED/BLACK for high voltage connections? You may spend quite a bit of time getting the BL touch to work and SENSORLESS homing, but in the end I did get everything to work exactly as I want with MARLIN.

Funciona excelente, le dió nueva vida a mi impresora. Súper silenciosos los controladores de motores, versátil en nuevas funciones.
