Beam Compressed Spot
More Precise with 5W Compressed Spot

Powerful High Speed Air Assist

Reference Settings for Engraving
For engraving, the focal point is at the surface of the material, the focal length of LT-40W-AA is 45mm, the length of the air nozzle is 38mm, so the focal point position is 7mm(45-38mm) below the air nozzle.
Put a 7mm thick focus fixing plate between the nozzle and the board for the best engraving point

Reference Settings for Cutting
For cutting, the ideal position of the focal point is in the middle of the material, the focal length of LT-40W-AA is 45mm, the length of the air nozzle is 38mm, so the focal point position is 7mm(45-38mm) below the air nozzle.
Cut 4mm plywood, the distance from the air nozzle to the surface of the material should be 7mm-4mm/2=5mm.
