Hello,
I want to buy a laser on cloudray to engrave medals with a 30mm diameter.
Ideally 55 medals, so a 150150mm surface.
You could find an example of file in my post.
My question :
When engraving 25 medals at the same time, does the details of the coins at the surrounding edge positions will be reduced ?
(Due to the field mirror setting, the light spot is the smallest and the laser energy is the strongest at the center point of engraving, and the light spot will become larger and the energy will weaken as the engraving range increases)
Is there a way to rectify this problem ?
Maybe use a big lens (300x300)
Thanks
