Oh... I wonder why I bought this now...
I am an early user of the Ender 3, and the board broke down so I had to replace it.
The speed is fast and there is no whirring sound.
The quality of the printed materials has also improved.

Well packaged, fast shipping, fully compatible with Ender 3 v1

Fully compatible with sovol sv06 no hardware modification needed and the stock screen works plug and play as well and most of the wires except one the needs to be made a plug for bcuz the original it's with screws. u can find a klipper firmware on github and you need a 8gb sd card it won't read larger

Working on an anycubic kobra neo v1 with klipper at 120mm/s! the only thing is that i replaced the heater cartridge and swapped the z-limit sensor for an ender 3 limit switch. i also removed the leviq leveling sensor.

A great board, with fully open-source hardware and software on github.

And it has an swd (serial wire debug) connector so you can develop and debug new firmware for the board! No other 3d printer board (that i know of) has an swd connector. Bigtreetech is unique!
