I am building my first driver with a adjustable hosel and I was wondering what length is the shaft to be cut at if it is standard length? it is a maltby pro head I believe a te4.

Ke4 with adiliA NV BLUE

depends on a couple of things. Standard length per Maltby chart can be 45 or 45.5 depending on shaft weight.
Assuming weight is 65 grams or greater and KE4 adapter installed, the total length will be right at 43.5″ (no grip installed).
