Tips and Tricks
- The harder the wood, the more power/less speed it will take to cut.
- Plywood takes more power/less speed than solid wood of the same thickness.
- The kerf of the laser is often around .5mm (or around .3mm on the big cutter). Keep this in mind if cutting pieces that are designed to fit together. (Kerf is the amount of material that is removed by the cutting element. With saws, it is the thickness of the saw blade.)
- The kerf will also be variable from the top to the bottom of the laser-cut piece, being wider on the top and thinner near the bottom. The variation will be more pronounced in thicker materials.
- Always test settings on your material before cutting your whole piece.
- It's best to cut in the top-left part of the bed. The power is strongest in the top-left corner and gets weaker as you move down or right. The difference from the top-left corner to the bottom-right corner has been measured as a 10% power loss.
- Plywood that's extra-charred? If the inner layers of the plywood have a knothole or a gap, glue can squeeze into that void and create an inclusion. The laser does not cut through glue well at all, so it fails to cut that spot. It also tends to create much darker soot. Running a bit slower might give you a buffer and allow you to cut all the way through it. A higher grade of plywood might help but its debatable. Unfortunately, its just a downside to using plywood.
