Hi,
sorry for writing in english. I have a U20 and wanted to install a BLTouch according to this tutorial.
My Board is a V0H so a newer version than V0H described here.
I have followed the tutorial and it worked very well. But my BLTouch Clone was not very good so i got always a panic stop (M112) when doing a Auto Bed Leveling G29.
So i bought an original BLTouch but this does not work. So when i manually try to stow the pin with M280 P0 S10 or M280 P0 S90. It does not react. When i start the Printer it does its self test which works fine and shine permanent red. So i thought it might be defect and bought another genuine BLtouch which shows the same behavior.
I have installed a 100KΩ resistor between red and orange wire. When i connect the BLTouch without resistor to the Board also no reaction when i try to manually stow the pin.
Is the resist
or with 100KΩ to large or is it a Problem with the newer Board version V0H. And why can i manually controll the BLTouch Clone but not the genuine one.
Perhaps someone can help.
