BIGTREETECHSKR Mini E3 V2.0 Control Board 32Bit New Upgrade for Creality Ender 3, with TFT35 E3 V3.0 Graphic Smart Display Controller Board 3D Printer Parts

Excelente tarjeta, solo falta mejorar el firmware ya que no funciona debidamente con CuraTengo cura 8.0 y marlin 2.0.7 como venia y no e logrado imprimir debidamente por múltiples fallas de comunicación entre impresora y computadora, parece que es un problema comun

Bought this and used it in a scratch build printer. Documentation for the V2 control board is there, but somewhat lacking. Being a popular board, there is enough info on the net to fill in the blanks. The board is well built and worked right out of the box. For firmware I used Cheetah 5.0 from Kay3D.com Their firmware is a version of Marlin that takes you through about 20 steps to configure a printer. All these steps are placed at the front of the Config files and notated so well it is almost impossible to screw up. If the notation in the config file is not enough, their online guide and video make it even easier. Many common printers are listed in the firmware with all their features, and simply selecting one, takes care of most your firmware choices. You will not find an easier firmware for setting up a BL Touch or any sensor. It is painless and almost guaranteed to work. All options are in the firmware for custom builds also. If you are not a firmware ace, be sure to try this firmware and make your life easy!Back to the board. The TMC2209 stepper drivers keep the motors silent. Sensorless homing works awesome. Do note that sensorless homing does NOT work on a Z axis with a lead screw. Settings are almost impossible to obtain. If you can get a setting that works, it will only be temporary. Digging into this issue I found right in Marlin where it says it will not work with a Z axis lead screw. Just something to be aware of. I had to add a limit switch on the Z axis. The TFT35 touch screen is plug and play. Documentation on connecting the serial cable to the control board is lacking, but again, the internet is your friend. The touch screen operates in either traditional Marlin mode or touch screen mode, and you can switch between the two. You will want to switch between the two for initial setup. Some settings are only available in the Marlin screen and some only in the touch screen. This is my only gripe, but in reality, once everything is setup it is no big deal. One really nice thing is the ability to change stepper drive current right from the touch screen. Gone are the days of a small screwdriver and multimeter to set each chip individually. I did have to turn up the current on my Z axis chip due to a subpar leadscrew.It's not perfect, but for the price it is really hard to complain about anything. The few minor annoyances are easily offset by the price. With this combination being so popular, there is plenty of info on the internet if you run into any issues.

The printer is more consistent now with clean layer lines. See left (before) vs right (after) in my attached pictures.And the noise! The same stepper motors are near silent with TMC2209’s StealthChop feature. I had to buy silent fans to cut out the next loudest bit of the printer. I picked up Orion 4010s (20dB) for the main board and hot end, and a Sunon 6015 for the PSU. Worth it for that alone.The TFT display I got with the board is great. Touch screen, easy to navigate, on-board SD card slot (not microSD without an adapter). Neat RGB LED on the dial. I don’t use OctoPrint (for now) so having a better display makes it that much better.Wiring is simple, take a picture of the original board and plug everything in to the same spots. With one exception: the blower fan, which is the yellow and blue cable, should be swapped with the main board fan. Meaning the main board fan should no longer be on the row with the rest of the 2-pin connectors, but above it, in the same position.A few notes:- I plugged my hot end fan in backwards and I thought I had an extruder or a hot end issue for a bit. Nope, that fan needs to be on to prevent heat creep. I had a clog for a little bit too until I fixed the wiring and cleared the filament.- I tried to use the included ribbon cable but it’s too short to route the way I like, so I stuck with the rainbow cable that I was using before.- Must put new firmware on the board ASAP. I downloaded the latest prebuilt firmware.bin from the official repo and put it on the 128 *MB* microSD included. This fixed a couple quirks I ran into.- You can’t print from the onboard SD + TFT mode without changing the installed firmware for a newer/custom version. You can in the LCD simulator mode. You’ll have to use the TFT’s SD card slot if you’re in the graphical mode otherwise.

Desde que la instalé, se quedado la impresora colgada a media impresión. Cuando funciona bien es un lujo...pero se me acaba de colgar en una impresión de 21h faltando una hora...🤬

This is a detailed 2 part review please take time to read....1.) This board is amazing! Installation was a breeze just recommend to take a before photo of the old board wiring before beginning and then be sure to pay attention to the wiring diagram online from BTT and after a little bit of time compiling the firmware on the card and uploading to new board the printer runs like a dream. so quiet you don't even know its printing all you can hear are the fans cooling. I do recommend watching the video on installing this board and compiling the firmware that's on YouTube by Chris's Basement very helpful.2.) Now on the back end of things the first board quit working after a few days couldn't get it to reset or work again even after re flashing the firmware. Amazon did replace free of charge and sent another out to me, however it was shipped in its own little box it was NOT placed into an amazon mailer of any kind no bubble mailor no outer box with cushioning there was nothing but a shipping label on the outside so of course the board was damaged in transit and I couldn't even use it. Since this was already a replacement sent out they could not send another one to me just a refund for the purchase price. This was ok however now I was left with no board for my printer and I purchased this board when it was on a one day sale and since the price had already increased again they could only refund the sale amount originally paid and now I must come up out of pocket the difference to re order one more time and hope for the best on the third attempt.
