Installing 3 pin connection
I'm going to solder a 3 pin header into the PB7 row connection, and use the breadboard jumper leads 300 mm in length extending the connection points of PB7 and Z-MIN out into the build plate area. This will facilitate connecting or removing the BLTouch sensor, and if need be allow me to use these connection for something else.
So how to achieve this - first you need to remove the top cover of the printer, it just simply lift's off. Because of the layout of the board, I suggest resting the printer on it's left side.
