Geeetech

Hi guys, trying to upgrade my "Geeetech i3 aluminum pro with lead screw update and 3 in 1 controlbox" with the 3D touch sensor.
Could someone pls share a already modified firmware for the printer with 3D Touch working and enabled? I'm new to 3D printing and have no skills in arduino coding, so before reaching my frustration level maybe someone could help? Thx

Since the extension board of A pro has no 3 pin slot, you have to drill a hole on the box for wiring.

Connect 2 pins to the extension slot, and 3 pins to servo 0 on the mainboard.
Then edit the firmware according to the user manual of 3D Touch.
