SKR 1.3 and BLTouch (clone) problem #170

Open javata70 opened 4 years ago

javata70 commented 4 years ago

Hi, I have a Bigtreetech SKR v1.3 and 3D Touch but the 3D Touch doens't work. I've tested the 3dTouch using some code in an Arduino Mega and does work perfectly. I'm using Marling 2.0 and when it starts the 3D Touch does a self-test and then the pin is stow and stays in this state forever without any change (throught M43 S or from the Marlin menu)

I found this article http://fightpc.blogspot.com/2019/08/testing-skr-13-board-with-marlin-20x.html that could solve the problem. Aparently some SKR boards could have an output signal that has a low impedance (around 200 ohms) that would require a significant amount of current to work properly (and it not happens on Arduino boards, that is the reason why my 3D touch probe works propertly on the Arduino)

Hey, have you found any solution yet? I have the very same problem and I have tried so many things that were suggested in forums but nothing helped. Did you get the Clone running with the SKR?
