You can't go any further up (except we got it to return by 65mm now) from wherever you begin.
I have inherited the laser from the prior administration so I can't speak too much to past decisions but some people have been here since the beginning so I do have some knowledge.
Like I said before, the U is addressed in the manual as the axis to raise and lower the bed, which is the main method for focusing the tool. The Z is referred to as the Feed Motor or such. Wire feed perhaps?
The laser head can move up in down a little bit if you loosen the nozzle but this is not mechanical, just a reality of the way it's constructed.
I can take some photos.
