Material Engraving Cutting Scoring Notes
Speed (mm/s) Power Speed (mm/s) Power Kerf Width Speed Power
Acrylic (1mm) 400 5 30 20 0.15mm The plastic has a tendency to stick back onto itself a little after cutting because it's so thin, so you may have to pop your pieces out
Acrylic (2mm) 400 5 30 20 0.15mm
Acrylic (3mm) 400 5 20 55 0.15mm Engraving: Power setting 4 and 5 have little visible difference except some minor lightening at the beginnings of cuts at power 4. Power 3.5 produces very light engraving, almost non-existent, with no engraving at the beginnings of cuts. Above power 5, little difference is visible, but powdery soot becomes more prevalent. Power 5 seems to be the best setting to produce frosted effects. If you are engraving with the paper still on, you may want to go higher (do a test)
Acrylic (4.76mm \ 3/16 inch) 400 5 16 55


Acrylic (6.35mm) (1/4") 400 5 8 55 0.15mm
Acrylic (12.5mm) 400 5 3 55 0.15mm Focal length is 4mm
Acrylic (18mm) 400 5 2 98 0.15mm Focal length is 4mm
Acrylic (19mm / 3/4 inch) 400 5 2 98 0.5mm at surface of cut, 0.15mm at bottom of cut Focal length is 4mm, one pass only. Peel off the top film of the acrylic. **The current settings does not guarantee a clean cut -- you may have to knock your pieces out because the bottom didn't quite go all the way through all the time. If you want to guarantee a clean cut and don't mind it being really slow you can use 1 speed 30 power, just keep an eye on it (slightly flamey)
Balsawood (3.2mm) 400 5 50 10 Engraving balsa produces little differences in power above 5, and below 3.5 or so, there's no engraving at all.
Balsawood (1.6mm) 400 5 50 7 Engraving balsa produces little differences in power above 5, and below 3.5 or so, there's no engraving at all.
Bamboo (3/32" nominal, 2.5mm actual) 400 3-20 55 45 Engraving power 3% produces visible, but very light, marking w/ no depth, 20% produces darker marking but w/ significant depth
Basswood (1.5mm) 400 5-20 50 15 Engraving above power 20 seems to produce no difference in color, only depth, see reference piece in toolbox.
Basswood (6.5mm) 400 5-20 20 55 Engraving above power 20 seems to produce no difference in color, only depth, see reference piece in toolbox.


Birch (0.9mm) 400 5-15 40 20 Engraving is very finicky; 4 is the absolute lowest the machine will engrave at, 15 is high enough to cause serious charring on birch. The 5-15 range is best. See the test engraving for what the 5, 10, and 15 settings produce.
Birch (4.8mm) 400 5-15 35 55 Engraving is very finicky; 4 is the absolute lowest the machine will engrave at, 15 is high enough to cause serious charring on birch. The 5-15 range is best. See the test engraving for what the 5, 10, and 15 settings produce.
Birch (1/4 inch plywood from Discount Builders Supply) 15 55 The actual thickness of this stuff varies a lot throughout the sheet, plus there are knots in the wood that are harder to cut through. These settings should work though.
Birch (1/2 in) 5 55 0.2mm

Denim 200 4 50 7 engraving numbers might produce very thin fabric, might fall apart in the wash

Douglas Fir (15mm) 400 3-25 3 80 power differences are mostly differences in depth not color; engraving produces different depths over the growth rings due to wood density changes = rippled surface

Fabric - 1000D Cordura Nylon 100 20 crisp heat sealed edges

Fabric - ~0.2mm polyester/cotton blend 100 10 crisp heat sealed edges

Fabric - 100% poly burlap from Amazon 100 7 ([1])
Fabric - 100% poly gabardine from Fabric Outlet 100 7 You do have to pull the cut fabric apart (it's not a clean cut), but it rips at the cut cleanly.
Fabric - 100% poly polar fleece from Fabric Outlet 100 7 lovely clean cut
Fabric - 100% rayon crepe from Fabric Outlet 100 7 You do have to pull the cut fabric apart (it's not a clean cut), but it rips at the cut cleanly. I think this is just a property of the fabric melting back together after being cut. I tried increasing the power and it didn't result in a cleaner cut.
Glassine (cellulose paper) 55 5 100 2
Grip Tape 50 20
HDPE (0.8mm, 1/32 inch sheet from TAP Plastics) 20 30 creates a beveled edge and a slight under-hanging lip
Laser rubber (2-3mm, low odor) 100 10 20 55 Low-odor laser rubber is typically grey, the normal kind is pink. Have not tested the latter yet
Leather (1.5 mil) 30 50 Can be smelly. Open all windows, turn on fume hood, apologize to other h4ckers
Leather (2.5 mil) 10 50 Can be smelly. Open all windows, turn on fume hood, apologize to other h4ckers
MDF (5/8") 100 4-7 5 55-75 400 5-15 Cutting doesn't go all the way through necessarily, it gets spotty at this thickness. The power range was tested and produced similar results throughout, but YMMV. Etch speeds given for *scan* etching (i.e. when you do a filled area). You can tweak the speed and power to get different effects. Simple line engraving may have different settings.
Notebook from Muji: Recycled paper notebook beige A5 plain, orange spine 50 5-35 5 will just score through the cover 10-15 will cut through, and 35 will cut through a few pages. Any higher and there's a fire hazard. Be sure to tape or weigh the book down flat or else it's more flamey.
Paper (printer paper) 55 5
Plywood w/ reddish tinge (2.6mm) 35 30
Plywood (3mm) 400 5-55 35 50 see reference in toolbox for engraving

Plywood (18mm, nominal 3/4") 400 5-55 3 85 speed and power is imprecise (3/85 cuts through fine sometimes, while 2/85 doesn't always cut through fine)

Polyethylene Foam (1/2") 55 35 Requires two passes, doesn't perfectly cut through but is easily separable
Polypropylene (0.5mm) 50 10 Ruth has found that 50 speed 20 power gives a cleaner cut for the 24x45 inch sheets from TAP plastics.
Polypropylene (0.5mm) 75 55 55% max power, 40% min power, pieces don't stick to the sheet like they do at the settings above
Polypropylene (1/4in) 4 55
Redwood (20mm) 100-400 55 3 55 5mm/s gets you almost there, so you could probably go over it a second time and it would work instead. Or if you sand it down a bit, that would probably work. I've only tried engraving on max power. You won't get a consistent depth, and it will vary depending on the grain of the wood. Looks col, but just be aware.
Red Oak (0.25 inch) 400 23 12 55 Engraving power 23 gives a dark engrave on a .5-1 mm line thickness. 12-18 gave a lighter engrave. When cutting a knot in the wood, you'll have to use a lower speed, 9-10 will probably work. This wood was high quality scroll wood with almost no knots.
Scotchlite 8930 55 10 Scotchlite, Reflective Material, 8930 Silver Flame Resistant Fabric
Silicone Sheet, 0.024" thick, black 80 50 50% max power, 30% min power. Not all cuts fall free, but increasing power/decreasing speed doesn't help, just makes more white powder. https://www.amazon.com/gp/product/B01N5MB2JK/
Silicone Sheet, 0.040" thick, black 50 55 55% max power, 30% min power. Remove clear protective sheet before cutting. https://www.amazon.com/gp/product/B06WCZD1LZ/

Sticker sheet (Avery 5975 Neon Assorted https://www.amazon.com/Avery-Labels-Rectangle-Assorted-Fluorescent/dp/B000093L5R) 200 7
Transparency Sheets 400 6 Only chlorine and speed/power tested a mystery brand from Switzerland that Henner bought; other brands may require tests again
Kapton Sheet 0.005" 200 20 For solder paste stencils I scan at 200mm/s, 20% power, 0.05mm interval. 30% power and 0.1mm interval is faster, but slightly less clean results
Clear Polystyrene (1mm) (Mr Plastics) 30 30
