Two suggestions

1/ Try to plan your work so you don't have to move the head. Measure up
your various tools eg your R8 collet chuck, drill chuck etc so you know in
advance how much room you need to change from one to another. Then when
starting a job you can set the head just far enough above the work to
extract one tool holder and replace it with another.

2/ Have a look in Model Engineers Workshop there have been a numbe of
articles on this. Quite a good suggestion was to bolt a laser pointer on the
mill head (Horizontal plane) and aim it at a wall some distance away. Draw a
vertical line on the wall. If the mill head is rotated when it is raised or
lowered then you can get it back into alignment by moving the head until the
laser spot is on the line again.
