Focus distance (different lenses)
The video below shows you how to manually set the correct focus height step by step. Every lens has an ideal focus height at which you can achieve the best cutting and engraving lines. It is important to ensure that you work at the correct focus height every time. Otherwise, you can end up with frayed and wide lines. As a result, you may not get through your material when cutting and you may also lose detail when engraving.
