Hello everyone!
I've been trying to install the BlTouch on the RAMPS, but when I connect it, the board starts to reboot (sometimes I'm lucky and I can check if the 3 axis move, but 90% of the time keeps rebooting). Reading through internet, I found that Arduino clones manages pretty bad the 12v to 5v conversion.
So, how can I power that 5v pin in a safe way? Keeping all the time the Arduino powered by USB at the same time the RAMPS is powered by 12v current? Modifing a 5v USB cable to match that 5v pin? I attach an image from one of the threads they talk about a similar issue.
The threat:
