What you will be able to do

Find the settings for a material by burning a grid, cut a sheet in less time, and engrave a photograph that does not come out as mud.

1 Focus test Find the height that puts the beam at its sharpest on this material. 3 steps 2 Material test grid Find the power and speed for a material you have not used before. 3 steps 3 Test burns Find the power and speed that cut this material cleanly. 3 steps 4 Calibrate axis Fix cuts that come out slightly bigger or smaller than the size you typed. 3 steps 5 Measure the beam width Find out how wide your beam cuts, so parts come out the size you asked for. 3 steps 6 Cut order Decide the order the parts cut in, and where each cut starts. 3 steps 7 Auto-nest parts Fit more parts on the sheet so less of it goes in the bin. 3 steps 8 Shared cut plan Two parts edge to edge share a cut. Running it twice scorches both of them. 3 steps 9 Remove shared cuts Stop the laser cutting the same line twice where two parts touch. 3 steps 10 Reverse cut direction Turn a path around so the laser runs it the other way. 3 steps 11 Engrave fill Fill a shape with sweep lines so the laser engraves it solid. 3 steps 12 Fill with lines Shade a shape with engrave lines instead of leaving it an outline. 3 steps 13 Fill with rings Fill a shape with rings that follow its own outline. 3 steps 14 Photo engrave Get a photo onto a part as something the laser can actually burn. 3 steps 15 Dot pattern engrave Fill a shape with dots instead of solid burn. 3 steps 16 Engrave the background Burn the background instead of the shape, so the shape stands up. 3 steps 17 Text Put words on a part as single lines the laser can follow. 3 steps 18 Text on a path Run words along a curve instead of a straight line. 3 steps 19 Thicken tiny strokes Make lines thinner than the beam wide enough to survive the burn. 3 steps
