A30T 3D Touch or sensor / Proximity Switch

[blindwilky]

Finally getting this printer to sing, doing some great prints now. It’s been testing to get it there ....
I’m using several beds now but although maybe not needed I’m manually checking the levels so thought I’d by auto sensor.
First issue no firmware for the 3D Touch, so I bought the proximity sensor and guess what can’t find that either.
Has anybody had any joy finding it for the A30T printer...
