The Gweike MCore uses two laser sources for different engraving materials. Use the 400W fiber laser for stainless steel, carbon steel, aluminum and brass. Use the 80W CO₂ laser for acrylic, MDF, standard wood board, leather, cloth, paper and confirmed laser-safe rubber board.

Every numerical value in this guide follows the uploaded MCore engraving parameter tables. The article uses the 400W fiber column and the 80W CO₂ column only. It does not use the separate 130W CO₂ values.

The settings below are starting references for material testing. The source tables do not state the number of engraving passes, so the listed depths must not be interpreted as guaranteed single-pass results.

For a broader explanation of the machine, see Gweike MCore: Desktop 400W Fiber + 80W CO₂ Laser Cutter Explained.

Quick Answer: Which MCore Laser Head Should You Use?

Metal engraving: use the 400W fiber head. The table lists one engraving depth—0.05mm—for stainless steel, carbon steel, aluminum and brass.

Non-metal engraving: use the 80W CO₂ head. The listed depths range from 0.1mm to 3.0mm, depending on the material.

Material MCore Laser Head Depths Listed in the Table
Stainless steel Fiber 400W 0.05mm
Carbon steel Fiber 400W 0.05mm
Aluminum Fiber 400W 0.05mm
Brass Fiber 400W 0.05mm
Acrylic CO₂ 80W 0.1, 0.2, 0.5, 1.0, 2.0 and 3.0mm
MDF (high-density board) CO₂ 80W 0.1, 0.2, 0.5, 1.0, 2.0 and 3.0mm
Wooden board, except rare hardwood CO₂ 80W 0.1, 0.2, 0.5, 1.0, 2.0 and 3.0mm
Leather CO₂ 80W 0.1, 0.2, 0.5 and 1.0mm
Cloth CO₂ 80W 0.1, 0.2 and 0.5mm
Paper CO₂ 80W 0.1mm
Rubber board CO₂ 80W 0.1, 0.2, 0.5 and 1.0mm

Important Notes Before Using the Parameter Tables

The source spreadsheets use the labels Engraving power, Nozzle height, Focus, Pressure, High speed and Best speed.

Unspecified units: the spreadsheets do not explicitly state a unit for the Engraving power values. This guide therefore uses Power Setting and does not add a percentage sign. The fiber table lists a Focus Setting of -8 but does not state its unit, so this article does not add one.

The tables also do not provide pass count, DPI, line interval, scanning direction or a statement that any listed depth is achieved in one pass. Confirm the software definitions and test the actual production material before saving a preset.

Fiber Engraving vs CO2 Engraving on MCore

400W Fiber

Metals listed in the table

Stainless steel, carbon steel, aluminum and brass.

The available reference depth is 0.05mm for each listed metal.

80W CO₂

Non-metals listed in the table

Acrylic, MDF, wooden board, leather, cloth, paper and rubber board.

The available depth range depends on the material.

The two laser heads are complementary rather than interchangeable. Use the source assigned to the material category in the parameter table. For mixed-material work, test each material and laser layer separately.

1.0mm 24–26 1–2 bar 800 mm/s 400 mm/s
2.0mm 30–35 1–2 bar 800 mm/s 400 mm/s
3.0mm 35–40 1–2 bar 800 mm/s 400 mm/s

The table does not provide different rows for MDF density, coating, veneer or binder formulation. Use extraction and clean the engraved area before evaluating the result.

Wood Board Engraving Settings

The source category is “Wooden board (except rare hard wood).” Use the table only for that stated category; it does not claim coverage for rare or unusually dense hardwoods.

Depth Power Setting Pressure High Speed Best Speed
0.1mm 12–14 1–2 bar 800 mm/s 400 mm/s
0.2mm 14–16 1–2 bar 800 mm/s 400 mm/s

3.0mm 35–40 1–2 bar 800 mm/s 400 mm/s

The spreadsheet does not provide separate values for plywood, basswood, walnut, oak, maple, bamboo or resin-rich boards. Test each wood product separately.

For cutting values, see the Gweike MCore wood and MDF cutting parameters.

Leather Engraving Settings

Depth Power Setting Pressure High Speed Best Speed
0.1mm 12–14 1–2 bar 800 mm/s 400 mm/s
0.2mm 14–16 1–2 bar 800 mm/s 400 mm/s
0.5mm 22–24 1–2 bar 800 mm/s 400 mm/s
1.0mm 24–26 1–2 bar 800 mm/s 400 mm/s

The table does not list 2.0mm or 3.0mm leather rows and does not separate genuine, vegetable-tanned, chrome-tanned, PU or other synthetic leather.

Material verification: confirm that coated or synthetic leather is laser-safe before processing. Stop if the material produces abnormal chemical odor, smoke or residue.

For cutting values, see the Gweike MCore leather cutting settings.

Cloth, Paper and Rubber Board Engraving Settings

Cloth

Depth Power Setting Pressure High Speed Best Speed
0.1mm 12–14 1–2 bar 800 mm/s 400 mm/s
0.2mm 14–16 1–2 bar 800 mm/s 400 mm/s
0.5mm 22–24 1–2 bar 800 mm/s 400 mm/s

The table does not list separate rows for cotton, polyester, canvas, denim or felt. Test the actual textile and confirm its composition.

For cutting values, see the Gweike MCore fabric and felt cutting parameters.

Paper

Depth Power Setting Pressure High Speed Best Speed
0.1mm 12–14 1–2 bar 800 mm/s 400 mm/s

No other paper depth is listed. Paper is heat-sensitive, so supervise the test and keep extraction running.

Rubber board

Depth Power Setting Pressure High Speed Best Speed
0.1mm 12–14 1–2 bar 800 mm/s 400 mm/s
0.2mm 14–16 1–2 bar 800 mm/s 400 mm/s
0.5mm 22–24 1–2 bar 800 mm/s 400 mm/s
1.0mm 24–26 1–2 bar 800 mm/s 400 mm/s

The spreadsheet uses the general category “rubber Board” and does not identify the polymer or additives. Process only rubber materials confirmed as laser-safe.

Materials to Avoid: PVC and Unknown Vinyl

Do not use the PVC rows from the spreadsheet. This guide intentionally excludes those values. PVC and unknown vinyl can release corrosive and hazardous fumes during laser processing.

Do not engrave PVC sheet, unknown vinyl, vinyl-coated fabric, unidentified plastic-coated materials or materials with unknown chlorine content.

Read why you should not laser cut PVC and safer alternatives.

High Speed and Best Speed Labels

Both source tables use the same speed labels:

Source Label Listed Speed
High Speed 800 mm/s
Best Speed 400 mm/s

The spreadsheets do not state that either speed guarantees the listed depth. Compare the two labels on the actual material while holding the other listed settings constant.

How to Control and Verify Engraving Depth

Use the correct material row

Select only a depth listed for the material. Do not use the 2.0mm or 3.0mm CO₂ rows for leather, cloth, paper or rubber board.

Keep Power Setting units unchanged

Use the number range from the table without adding an unverified percentage unit. Confirm the software field before production.

Record speed, pressure and focus

Fiber rows include nozzle height, Focus Setting and pressure. CO₂ rows include pressure and both speed labels but do not include a focus value.

Record pass count

The source tables do not state the number of passes. Record it during every test and do not describe the listed depth as a guaranteed one-pass result.

Measure the result

When engraving depth is a production requirement, measure the test result rather than judging only by color or appearance.

How to Test a New Material

Identify the exact material

Record the material name, grade or type, thickness, surface finish, supplier, batch and any coating or backing.

Select the correct laser source

Use 400W fiber for the four listed metals and 80W CO₂ for the listed non-metals.

Choose a listed depth

Do not extrapolate unlisted depth rows or transfer a row from one material to another.

Use the matching parameter row

Keep the Power Setting, pressure, speed and any listed nozzle or focus values together.

Run a small test

Use a small text sample, square or logo section before processing the complete workpiece.

Change one variable at a time

Avoid changing power, speed, pressure, focus and pass count simultaneously.

Save the verified preset

Record the laser source, material, batch, target depth, Power Setting, speed, pressure, focus, nozzle height, pass count and measured result.

Troubleshooting MCore Engraving

The engraving is shallower than the listed depth

Confirm the correct laser source, material row, Power Setting range, speed label, pressure, focus where listed, workpiece flatness and pass count. Do not jump to an unlisted depth row for that material.

The engraving is deeper than required

Test a lower value within the listed Power Setting range, compare the High Speed label and reduce pass count. Change one variable at a time.

Acrylic is melting or becoming rough

Check the selected depth, Power Setting, speed, pass count, extraction and acrylic type. The table does not separate cast and extruded acrylic.

Wood is heavily darkened

Check the listed Power Setting, speed, pass count, extraction, wood density, resin and surface coating. The source category excludes rare hardwood.

Leather is too dark, stiff or produces abnormal odor

Use a shallower listed depth, verify the material composition and stop if the leather contains an unknown synthetic coating or backing.

Metal engraving depth is inconsistent

Check the 5mm nozzle height, Focus Setting -8, pressure 5–6 bar, material flatness, surface cleanliness, grade and the selected Power Setting range.

Frequently Asked Questions

Which MCore laser should I use for metal engraving?

How deep can MCore engrave leather?

The 80W table lists 0.1, 0.2, 0.5 and 1.0mm for leather.

Does Power Setting mean percent?

The spreadsheets do not explicitly state the unit for Engraving power. This guide therefore does not add a percentage sign.

Is Focus Setting -8 measured in millimeters?

The fiber table does not state the unit. Confirm it in the current MCore software or operating documentation.

Are the listed depths single-pass results?

The source tables do not provide a pass count, so the listed depths must not be described as guaranteed single-pass results.

Can MCore engrave PVC?

This guide does not publish the PVC rows. PVC and unknown vinyl can release corrosive and hazardous fumes during laser processing.

Need one system for metal and non-metal engraving?

Gweike MCore combines a 400W fiber laser for supported metals with an 80W CO₂ laser for approved non-metal materials.
