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.

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.

Purchased a used Ender 3 to repair, had an older Creality 4.2.2 mainboard with the noisy stepper drivers and a failed SD card port. Have run machines with the BTT SKR boards before, but the E3V2 was a direct fit and easy to install. Took ~30 minutes to tip machine over, remove cover and motherboard mounting bolts, swap wires over one by one, and power back up. Please be aware, that the cooling fan on the Ender 3 case plugs into the FAN1 plug, and only spins when the stepper motors are enabled. I was worried I got a dud at first, but make sure to hold off on returning until you home the machine and see the FAN1 turn on. Completely eliminates noise from the machine operation, makign the fans the loudest part of operation. I was able to do a test print immediately after installation without any firmware updates or changes. Would recommend highly, cheaper and just as good if not better than the stock Creality boards.

Way quieter than the stock (non-silent) Creality board. Makes my prints look slightly better as well. Definitely worth upgrading to just for the better firmware customization alone. I used TH3D's Unified 2 software, was planning on using Marlin, ran into some problems as the branch for the Ender 5's config files in the BTT GitHub was apparently not for the same version as the bugfix version of Marlin. Apparently this has been fixed but I've never needed to go back and customize my fw any further. I will probably switch to Marlin sooner or later. If you need help setting this board up, Teaching Tech has great videos on this. Followed his Ender 3 video and it went well, even though Marlin didn't work for me, it was still useful to know where and how to do things like flash the firmware and where the cables go. He provides the needed diagrams. If you buy this board and plan to switch out a stock creality board, you will quickly find out that hot glue is possibly the worst thing in the world.
