The BLtouch V3 has caught a lot of people out because it isn’t compatible with the some Creality and other mainboards. Fortunately, enough time has passed for Antclabs and the developers of Marin to create some fixes, three of which I demonstrate in this video.

These firmware fixes will eventually be implemented into the main Marlin branch, and this video will become redundant.

All three of these options made the BLtouch V3 work with my Ender 3 housing a 1.1.5 board. Since the 1.1.3 in the first Ender 3/5s and the 1.1.2 board in the CR-10 are very similar, it should work for those too.

I realise that I went over method 2 very fast, and that’s because I’ve already made a video on that process: https://youtu.be/sUlqrSq6LeY
