Get a visual on your laser's focus. Simple and easy to use with inexpensive aluminum business cards from Amazon.
Make a sharpie mark about halfway up the ramp and use that mark to set focus with your ruler as you normally would. See photo.
Be sure to square the ramp with the holes on the laser's baseplate. See photo.
Lines should be placed .5mm apart. Sorry I can't upload a Lightburn file here.
Burn lines at a very low power. On my 60w MOPA I used 1000 speed @ 10% power.
After burning your sharpie mark should be in the CENTER area of deepest part of engraved lines if you are focused correctly. If the sharpie mark is above or below the center area, your focus is off and you should adjust focus accordingly and test until it's centered.
