BIGTREETECH SKR Mini E3 V2.0 Control Board 32Bit 3D Printer Parts

I recently upgraded my Ender 3 with the BIGTREETECH SKR Mini E3, and it has completely transformed my printing experience. This board is a drop-in replacement for the stock Creality board, making installation super easy. It fit perfectly, and with the pre-installed firmware, I was up and running in no time.The biggest improvement is the silent stepper drivers—my printer is now whisper-quiet compared to the stock board. No more loud motor noise, just smooth, precise movements. Print quality has also improved, with noticeably fewer artifacts and better control over retractions.Another great feature is the 32-bit processing power. Compared to the stock 8-bit board, everything runs smoother, from faster calculations to better handling of complex prints. It also supports Marlin 2.0, giving me access to advanced features like linear advance and thermal runaway protection for added safety.For anyone looking to upgrade their Ender 3 (or similar printers) with a silent, powerful, and reliable mainboard, the SKR Mini E3 is an absolute must-have. Highly recommended

Gosh, it's been a minute since I bought and installed this board into my Ender 3 Pro. It was a simple process of swapping out the original board, no wiring modifications were needed.Initially, I flashed a custom build of Marlin onto it as I wanted a few extra bits that weren't included in the BTT build on their GitHub page. Recently, however, I installed a CR Touch for Auto Bed Levelling (again, a simple addition to this board) and used the BBT BL-Touch build and it works perfectly - although it does probe the bed quite slowly and in a 5x5 grid which takes just over 3 minutes. I may recompile a custom build in the future to speed the ABL up.The board runs the stepper motors almost silently. I'm able to increase my print speed from 50mm/s to around 120mm/s with only very minor finish quality issues, anything faster and the defects/artefacts get more pronounced and take more post-processing.All in all it's been very stable and very quick. A huge improvement on the stock board & with the addition of ABL, it's increased the usability of the printer. Although not necessary, I may invest in the accompanying touchscreen upgrade for its extra functionality and Full-sized SD card slots.

The loudest part of my 3D printers now are the fans! I have 2 3D printers which both had noisy stepper drivers (Ender 3 Max with Creality 4.2.2 (The Z Axis has the noisy stepper motor) and Ender 5 Plus with 8 bit motherboard with A4588 stepper drivers), after looking at some options I opted to get 1 of these for my ender 3 max as the board is a direct replacement for the creality mainboard.BTT didn't have readymade firmware for the ender 3 max so I had to compile my own which helped me tune the printer more to suit my needs (I use Octoprint so really don't need the LCD screen / options) along with enable some features I wanted as well as disable other features I didn't want. Overall this took longer than installing the mainboard but now I have a 3D printer that works exactly as I want.On the back of my successful upgrade to my Ender 3 Max I bought another along with a touchscreen for my Ender 5 Plus, this was slightly more involved from an hardware perspective but the mainboard was also pretty easy to install. Again BTT did not have some pre-compiled firmware for my printer so I set about compiling my own which I've done several times now so was relatively straight forward. Within half a day I had gone from a very noisy 3D printer to a 3D printer that was near silent with the exception of the fans.I've been running both now for almost 2 years without any problems relating to the mainboard and recently made the jump to Klipper on the Ender 5 Plus, this board works really well with Klipper and so far I'm loving the features that Klipper unlocks.If you have a printer that isn't the latest (K1 / E3 V3 / P1 / A1 / X1-C) style then this is a great way to update an old 3D printer!

Firstly this is a very good board which is very quiet, and so I'm pleased with it now I have it installed. The issue is the installation wasn't the most straightforward.This board can be used on all Creality Ender 3 printers, so I bought this for my Ender 3. There are some great YouTube videos out there which will be of great help when installing this. I followed one and it went well apart from the fact that you need a JST connector for a pair of wires for the hot end fan. So I ordered 620 as you can't buy just one, which I discovered were the wrong ones when they arrived. I then ordered the correct ones, and had to buy 500 of them. With the wires prepared in the JST connector I was able to plug the connector into the mainboard and then use the printer again.These are the connectors you will need to order: https://www.amazon.co.uk/dp/B086W9HB3M/ref=pe_27063361_487055811_TE_dp_1You will just need a 2 pin one, and will need to wire the hot end fan wires into it and plug it into 'Fan 1' on the mainboard. Watch a YouTube video to make sure you get this correct and get the polarity order right.Overall I'm pleased now it's working, and as I said, it's a great and very quiet board. What frustrates me is that instead of the little rubber duck they include in the packaging (which would be a dangerous choke hazard for a child, and is just a useless object to otherwise have lying around), it would be great if the manufacturer would include just one JST connector, which would probably cost about a penny.
