I know I have read some topics that had pictures of a test grid that people use to tune their laser that basically burns a square at different percent powers, but I have spent the last day searching and can’t find it. Can someone point me in the right direction. There was also a topic on different z heights to find the optimal laser height. I know I could generate these files myself, but I’m sure some thought has been put into these. Any good resources for getting your laser dialed in would be appreciated!
Easy way to find the optimal laser height is to take a piece of material you want to laser, about 6 to 12 inch long 1/2 inch wide or so. Set the material as a incline. One end at waste board level, the other end 1 or 2" . Set the laser head just above the top of the incline. set your power just enough to burn. Burn a line the lenght of the incline. Dont move the incline, inspect to see the sharpest cut. measure the distance from head to incline part. that is your focal lenght
I feel like I am pretty much dialed in. I am really impressed with lightburn and will most likely purchase it unless I find a better alternative in the next 30 days. It looks like there are quite a few websites like this that generate lightburn project files for things like boxes, etc…
