Stepper motor pulley/ gear

How far should my pulley be into the stepper motor post.

Is this to far in? I took it apart and this is what I discovered on my x axis on a Shapeoko pro.

It should be positioned so as to line up with the flanged idler bearings so the belt runs true.

These are my y stepper motors. As you know the x on the Shapeoko pro are a hidden, that’s when I discovered it was pushed to far in.

No, see pg. 26 of:
