The laser will burn a straight line from left to right.Ħ) Without moving the piece you just burned, find the thinnest point of the line. Make sure the laser head is high enough to clear the highest point of the wood by just a mm or 2.ĥ) Start the job in Lightburn. A scrap piece or wood, or anything that raises it is fine.

Then you elevate the left side by placing something under it about 2' tall. I have yet to find a laser manufacturer that recommends the correct focal distance! This is a quick and easy test!ġ) In Lightburn, set the laser origin to absolute coordinates on the laser tab.Ģ) Use the pencil tool and draw a 9' straight line from left to right.ģ) Jog your laser to the beginning of the line using the set laser position icon on the left toolbar in Lightburn (Looks like a map pin).Ĥ) Now at the laser, take a piece of wood about 10' in length and place it under your laser head on the X-Axis (Left to right) in the left most position. No matter what any manufacturer tells you, the best way to focus a laser is a ramp test.
