Is engraving or cutting faster?

Engraving a small area is usually faster than cutting its outline, because the head moves fast at low power. But a large filled engraving can take much longer than a short cut, because the laser scans thousands of lines.

Scoring is a shallow line cut, vector-based, at lower power or higher speed than a cut. It marks fold lines, panel details or a thin outline without going through the material.

Which should I run first, engraving or cutting?

Engrave first, then score, then cut. If you cut first, the piece can shift or fall, and your engraving will be misaligned.

Why does my engraving look blurry or striped?

Common causes are line interval too wide, focus off, speed too high for the machine, loose belts or vibration. Check focus and interval first.

Can a diode laser engrave and cut?

Yes. Diodes engrave wood, leather and coated metal well and cut thin wood and cardboard. Cutting thick material takes many passes.

Laser Engraving vs Cutting: Differences and Settings

The first time you watch a laser engrave a photo on wood, it feels like magic: a picture slowly appears, line by line, with that warm toasty smell. Then the laser switches to cutting the outline, slows down, flares a little at the edge and drops the piece out. Same machine, same beam, two completely different jobs.

Understanding laser engraving vs cutting is the key to clean files and good settings. This guide explains what each does, how the software treats them, and what typical settings look like on diode and CO2 lasers.

What laser cutting does

Cutting is vector work. The laser follows a line, a path, and burns completely through the material along it. The head moves slowly, the power is high and the result is a piece that separates from the sheet.

Follows outlines (hairline strokes in SVG, polylines in DXF).
Slow speed, high power, maybe several passes.
Output: parts separated from the sheet.

In our files the cut path is a red hairline. See what is a hairline stroke for why thin lines matter.

What laser engraving does

Engraving changes the surface only. There are two ways to do it.

Raster (fill) engraving. The head sweeps back and forth, line by line, like an inkjet printer, firing the laser where the image is dark. This fills areas, shades photos and makes logos. In LightBurn this is Fill mode (for vector shapes) or Image mode (for photos).

Vector engraving (line). The laser traces a line at low power, for lettering, thin details and scoring. In LightBurn this is Line mode with low power and high speed.

	Cutting	Raster engraving	Line engraving / scoring
Follows	Outline	Scanned lines across area	A path
Depth	Through the sheet	Surface, a fraction of a mm	Shallow groove
Typical power	High	Low	Low to medium
Typical speed	Slow	Fast	Medium to fast
Time	Short for small parts	Can be long for big areas	Short
Used for	Ornaments, boxes, shapes	Logos, photos, textures	Fold lines, outlines, details

Typical settings side by side

Every machine differs. These ranges are common starting points for 3 mm plywood. Test on scrap, and use a test grid before the real job.

Laser	Cut speed (mm/s)	Cut power	Engrave speed (mm/s)	Engrave power
Diode 10 W optical	3–6, 2–4 passes	100%	60–150	20–50%
Diode 20 W optical	6–15, 1–2 passes	100%	100–250	15–40%
CO2 40 W	8–15, 1 pass	60–85%	150–300	10–25%
CO2 100 W	20–40, 1 pass	45–70%	300–500	8–20%

Notice the pattern: cutting is about 10 to 20 times slower than engraving, and engraving power is a fraction of cutting power. For more detail on engraving wood, see speed and power for engraving wood, and for cutting details LightBurn settings for 3 mm plywood.

Pro tip: If an engraving is too dark, raise speed before lowering power. Lowering power too far on a diode can leave an uneven burn, while a higher speed keeps the beam stable.

Line interval and resolution

For raster engraving, the distance between scan lines (line interval, or DPI/LPI) decides how smooth the result looks. A common value for wood is 0.1 mm, roughly 254 lines per inch. A finer interval (0.06–0.08 mm) gives smoother grey shades but takes longer and only helps if your laser spot is small enough. A coarser one (0.15–0.2 mm) is faster and fine for bold logos. See what DPI to use for laser engraving.

Interval	Lines per inch (approx.)	Use
0.05–0.08 mm	320–500	Photos on CO2 with fine focus
0.1 mm	254	General wood engraving
0.15–0.2 mm	127–170	Fast fills, bold shapes, deep texture

Combine them: engrave first, cut last

Almost every real job is both. Take the cat ornament from our library: the cat's details are an engraving, and the outline is cut. The order matters.

Engrave (black fills) while the piece is still attached to the sheet and perfectly held in place.
Score, if you have any score lines.
Cut last, so nothing moves before the engraving is finished.

In LightBurn, set the order in the Cuts / Layers panel. Many software packages follow the layer order or let you drag layers up and down. Our SVG files use a red hairline for CUT and a black fill for ENGRAVE, and the DXF has layers named CUT and ENGRAVE, so your software maps them without surprises. For more on layers see cut, engrave and score layers.

Common mistake: Cutting first and engraving afterwards. When the piece falls out, it can shift by a millimetre or tilt and the engraving lands in the wrong place. Engrave first, cut last.

Material matters

Not every material engraves the same way.

Material	Engraving look	Notes
Plywood, basswood	Brown contrast	Birch and poplar differ in tone
Hardwood (maple, alder)	Light to medium brown	Needs slightly more power
Acrylic (cast)	Frosted white	CO2 only; diodes cannot mark clear acrylic well. Engrave from the back, mirrored, for a neat look
Leather	Dark burn	Low power; smell and fumes need good ventilation
Coated or anodised metal	Marks coating	Diode and CO2 only mark the coating, they cannot cut metal
Glass	Light frost with CO2	Do not attempt with a diode, it does not absorb the light

Use fume extraction for everything, and check laser cutter safety.

Troubleshooting engraving versus cutting

Symptom	Likely cause	Fix
Engraving is pale	Speed too high or power too low	Slow down 20%, raise power by 5–10%
Engraving is too dark or charred	Too much power, interval too tight	Raise speed, widen interval
Stripes in the fill	Loose belts, bad focus, vibration	Tighten belts, check focus, secure the bed
Cut leaves tiny bridges	Corners or focus issue	Slow down, add a pass
Cut edges scorched	Too slow, no air assist	Faster speed, air assist on

Pro tip: Run a small test (a 20 × 20 mm square with a bit of fill plus a cut outline) at the start of every session. If both come out well, the real job will too.

Which one should you choose?

Some jobs are obvious, and some depend on what the customer sees. Use this quick guide.

You want	Use
A shape that separates from the sheet	Cut
A picture, logo or text on the surface	Engrave (fill)
A thin outline or a fold line	Score (line, low power)
A name on a cut-out ornament	Engrave first, then cut the outline
A see-through pattern, like a lace panel	Cut

If you sell on marketplaces, a neat engraving on a plain cut shape often looks more valuable than the shape alone, and costs only a minute or two more machine time.

Time and cost: engraving can be the slow part

A common surprise is that a big engraved area can take longer than the whole cut. Our reindeer ornament has a cut length of 0.47 m, which is under two minutes on a 10 W diode, but a large filled engraving of the same size could take ten minutes or more. If you are making many pieces, keep engraved areas small and bold, or use a slightly wider line interval.

Next step

Download an ornament such as the cat ornament and set up the two layers yourself: engrave at the Fill mode settings from the table, then cut with your tested cut settings. Seeing the engraving and cut in one clean job teaches you more than any article.
