Sorry, I’m not able to access my PC for a while so I can’t look. All I did was google something like ender 3v2 bl touch firmware and went from there.

100% agree on the bed level sensor. I have a BL touch and it is far and away the best upgrade for my ender 3v2.

I’d definitely recommend anyone adding a touch sensor play around with different firmwares. I was running a very buggy firmware for about 2 years and didn’t realize I could just find something that works better. My new firmware works so much better and has so many more features, all in a $0 upgrade.
