BIGTREETECH Direct SKR Mini E3 V2.0 32Bit Silent Control Board Integrated with TMC2209 UART Stepper Motor Driver for Upgrade Ender 3 Pro/5 3D Printer

I bought this when i was upgrading my ender 5 plus to Klipper. The board is silent so it was a welcome change from the noisey 8 bit unit. Big tree tech has tons of support documents to aid in the upgrade abs the model fits the stock boards footprint.

El paquete llegó algo aplastado, pero eso es cosa del sistema de envíos de Amazon y no es culpa del comprador. Por suerte la tarjeta no se dañó y funciona sin ningún problema.Gracias a los drivers TMC2209 que vienen en esta tarjeta la Ender 3 se vuelve bastante silenciosa, básicamente el único ruido producido por la impresora se debe a los ventiladores. Además, a estos drivers se les pueden cambiar los voltajes de referencia directamente desde una terminal con gcode, ya no es necesario tocar los potenciómetros con un destornillador e incluye un puerto extra para conectar un segundo motor del eje z, por si en algún momento deciden modificar su Ender 3 con doble eje z.En general totalmente satisfecho con la compra, definitivamente recomendada.

Runs smoothly. Mine came with the basic firmware already loaded in the motherboard. Make sure to pull up the cable layout on their site and notate what cords go where on your original board. Teaching tech on YouTube has a great reference video for ender 3 users.

Installed this on a ender 5 plus and it works great and makes the printer very quiet. Unfortunately this is the second board I installed since the first one was defective. Some time in QC could have prevented the first defective one that I got. All and all it's a good board and a worth while upgrade for the ender 5 plus.

Bought this for my 2020 ender 3 pro, along with their tft35 e3 v3 touchscreen and a genuine bltouch. My printer is so much quieter now. I'd consider this a must-have upgrade for an ender 3 pro. Install wasn't extremely difficult, but there are some things to note.1. Unplugging cables from your stock ender motherboard is a pain because they put hot glue all over the plugs at the factory. You will spend a significant amount of time removing those hot glue blobs before you can unplug all your e-motors and end stop switches. This was probably the most time consuming part of the install for me.2. Swapping the wires from the old motherboard to the new motherboard can be tricky. The main power wires aren't very long so I had to move wires over from the old board to the new board one at a time, with the new board hanging right in front of the old board.3. For firmware you have two options. Either run the latest pre-compiled firmware for your printer from the BTT github(with options for ABL or no ABL) which is as easy as putting the file on an SD card and turning on the printer which auto-installs the firmware from the sd card, or download the latest marlin release source files and edit/compile your own firmware. I won't get in to the details here but editing/compiling your own firmware is much better and you'll end up with firmware that is better tailored to your printer, and you'll have a better baseline to tweak in order to dial in those prints and ABL performance. Plenty of guides and videos out there for editing/compiling marlin firmware, and marlin has a discord with plenty of really helpful folks to give you advice or instructions if you need it.
