How to choose the correct
scan gap
It makes no sense to choose the highest possible DPI,
if your laser point dont matches the size of the scan gap.
-
How it works:
- 1. Make sure your mirrors are aligned perfectly
- 2. Make sure you did a ramp test, so your focus is perfect
- 3. Do a quick "Shot" with your laser, and measure the dot
(I would use Acrylic) - 4. Search your dot size in the table
- 5. Use the DPI next to the size for all of your images now
