The shield is 5mm above your material
when set with the kickstand/height gauge .
You can make a simple tool to set the height anytime you need to.
This is only for those rare, occasional times that you do forget to focus.

If you like to De-Tune your laser, you can make a tool the height you want
and avoid all the guess work each time you focus your laser.

Shield Clearance Height is the Same for D1 and D1-Pro
