This is my personal material library for the 22W Creality Falcon 2 laser engraver. These are approximate values that looked good to me during my tests.
| Material | Thickness | Effect | Speed | Power | Passes |
|---|---|---|---|---|---|
| Stainless Cup6 | n/a | engrave | 9000 | 50% | 2 |
| Painters Tape7 | n/a | engrave | 12,000 | 50% | 1 |
| Glass1 | n/a | engrave | 12,000 | 70% | 1 |
| Paper2 | 0.12mm | cut | 12,000 | 80% | 1 |
| Paper3 | 0.12mm | engrave | 15,000 | 60% | 1 |
| Cardboard | 3mm | cut | 1,000 | 40% | 1 |
| Cardboard | 3mm | cut4 | 1,000 | 30% | 1 |
| Cardboard | 3mm | engrave5 | 12,200 | 70% | 1 |
| Plywood | 3mm | cut | 400 | 60% | 1 |
| Plywood | 3mm | engrave | 10,000 | 90% | 1 |
| Plywood | 5mm (1/8") | cut | 400 | 95% | 1 |
| Rock8 | n/a | engrave | 1000 | 50% | 1 |
1 A flat sheet of dollar store glass was etched with a sheet of 24lb bright white paper under it. This caused the back side of the glass to etch.
2 Paper was 24lb bright white with another sheet under it. A slightly higher power, maybe 90%, might work even better.
3 Very thin paper is difficult to etch without losing the integrity of the paper.
4 At 30% the cardboard cut through but required pressing the part out while at 40% the part falls away freely.
5 This was tested as a cut instead of a fill shape so further testing may be necessary.
6 Engraving worked at speed 9000 and power 50% with two passes on most materials. Blue powder coat may not etch all the way through.
7 Blue painters tape over a black surface will etch through the tape, instead of into it, even at very low power.
8 Rocks will vary widly. This setting worked but caused sparks (and a fire warning from the machine). The etch was not very visible.
