Is the C-Mount Thread Always Starting at the Same Place?

There is no defined uniform starting point for the lens thread for the Basler ace.

If you compare two ace cameras, you will most probably see that the C-mount threads do not start at the same place.

These ready-developed carriers will not be further developed in this respect.

For the ace 2 this requirement has been directly included when developing the new front part.

The mount thread of the ace 2 always starts at the same point.

The above picture details the thread starting position for an ace 2 PRO and an ace 2 BAS. It is similar.
