![]() TinyFab suggested using a 10k resistor between 5V and the signal. This meant that I needed something to make the signal go high against the GND pin. As can be seen, by the diagram, there is a transistor attached to pin 1.18 that pulls the signal low on a high from a pin. I hoped life would be easy and I could just connect the three pins to the auxiliary connector on the extruder. Then came the next challenge connecting the actuator. So I started with the easy stuff solder a socket to the mainboard for the door check like so Port 2.13 - This is attached to the door check on the mainboard. ![]()
