🚀 Abunda's Overview

This is our summary and key points to consider based on customer reviews.

The BTT Mini E3 V3 Mainboard is generally appreciated for its high quality and significant contributions to upgrading 3D printers, making them quieter and faster. One unexpected perk enjoyed by users is a small rubber duck included in the package, which is regarded as a fun and whimsical companion that seems to boost the printer's speed and accuracy. However, it appears that the mainboard is not a suitable choice for all models of 3D printers, especially the Ender 5 Plus, as it made the setup more complex and difficult.

Pros

  • 🦆 Comes with a fun and whimsical rubber duck that adds joy to the printing process.
  • 🤫 Has TMC 2209 drivers that make the printer very quiet.
  • 🔧 Offers potential for significant upgrades to printers.
  • 🔨 Provides ease of firmware update by just dropping a 'firmware.bin' file onto SD card and turning the printer on.

Cons

  • 🔌 Installation can be challenging, particularly if upgrading from a stock board that has components hot-glued.
  • 💡 Configuring the firmware for ABL with BLTouch can be tricky, due to lack of comprehensive instructions.
  • 🖨️ Not suitable for Ender 5 Plus and can cause complications.
  • 🔒 The board may require advanced skills to set up, as it is not exactly a plug and play.

Should I Buy It?

If you are a hobbyist or professional who is prepared for upgrading your 3D printer and are ready to leverage the mainboard's full potential, then this product is recommended. Keep in mind, though, that it might not be suitable for Ender 5 Plus and requires manual setup, thus it's not a plug-and-play solution. If you’re unsure about this, it might be good to stick with what you have, especially if it’s already serving you well.

    • A great board for an Ender 3, a great board for any other printer.
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. ... show more

    • A Game Changer for 3D Printing: BIGTREETECH SKR Mini E3 V3.0 Review
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. ... show more

    • Nice Replacement for the CR10. Just be careful for the USB connector.
Review Image by Scott Masters Scott Masters
5 stars with one issue. The usb connector broke off as soon as I plug in a cable in. It was not soldered down properly. I got a replacement unit and added solder to anchor it down. I replaced my Creality CR-10 V2 mainboard using Klipper. This unit is working perfectly. The install was relatively straightforward. ... show more
