Ender3 All Metal Direct Drive Upgrade

Maybe add this one as well. Can be useful for CR10s users.
If you want to use PIn11 on CR10s here the schematic to connect the BLtouch. It can be frustating find the right diagram. This one is correct. You basically need to connect the SERVO to 5v adn GND and then the orange (servo) to the PIN 11. It can also be another pin but then remeber to set it correctly in the software.
The white and black cable replace the Z limit switch in the order as shown, or the sensor won’t work. If when you turn on the printer the BLtouch starts a couple of cycle where it moves the probe up and done, the wiring should be fine. Then time to upload the firmware.


Based on the version Cr10s can come also with a slightly different board. In that case the connections stays the same. Here the diagram. Remember to conncet the white cable towards the center of the board.
