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 || || || |} {| border="1" cellpadding="5" cellspacing="0" |- ! colspan="10" bgcolor="#cccccc" | Good Materials (continued) |- ! rowspan="2" style="width: 200px;" | Material ! colspan="2" | Engraving ! colspan="3" | Cutting ! colspan="2" | Scoring ! rowspan="1" style="width: 500px; | Notes |- !

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 (1/8 inch, square foot for $2.99 from Discount Builders Supply) || || || 50 || 55 || || || || |- | Plywood (5.6mm) || 400 || 5-55 || 15 || 55 || || || || see reference in toolbox for engraving |- | Plywood (9.5mm) || 400 || 5-55 || 7 || 55 || || || || see reference in toolbox for engraving |- | Plywood (12mm) || 400 || 5-55 || 5 || 55 || || || || requires overcutting beginning/end; 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) |} {| border="1" cellpadding="5" cellspacing="0" |- ! colspan="10" bgcolor="#cccccc" | Good Materials (continued) |- ! rowspan="2" style="width: 200px;" | Material ! colspan="2" | Engraving ! colspan="3" | Cutting ! colspan="2" | Scoring ! rowspan="1" style="width: 500px; | Notes |- ! Speed (mm/s) !! Power !! Speed (mm/s) !! Power !! Kerf Width !! Speed !! Power || |- |- |- | 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/ |- | Silicone (HT 6135 elastomer, Marian Chicago) || || || 22 || 12 || || || || |- | 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 || || || || |}
