Prusa i3 Pro W 3d touch not working

[Melita01]

hi all i downloaded the firmware for my printer here: https://snaptube.cam/ and it says with 3d touch but i seem to not be able to get the 3d touch working no mater what i do im just wondering if anyone cant help

the light is on and turns of when i pull it down and when i first turn on the printer it goes up and down.
I have put g29 after g28 but even when i send commands it doesnt move so i think its a firmware issue but it might be a wiring issue i dont know. i have checked all the wires go to the right place but i dont know how to check if the wires are getting the signals. does anyone have any experience with the 3d sensor and geetech pro W's?

any help is appreciated
