Guys thanks for all your answer.
As I am a “noob” with this software and it is the first time I use a NeJe laser I need a bit more explanation, I understand it may be very easy, but not for me.
Regarding the dot matrix font, even if I find how can i install it in lightburn? I have iOS (MacBook Pro)
Otherwise you suggest me to draw a simple line font and through create it the dots, am I right? Is it something like discussed in this past topic here? Even if material is acrylic instead paper and are not dot matrix seems the same procedure to create dots.
