CO2 speed and power units
CO2 Engraving Speed and Power Reference
Convert an approved speed between mm/s, mm/min, in/s, and in/min. Keep controller power percentage separate from measured optical watts, and preserve the test conditions before reusing a setting.
Content reviewed 2026-11-02. Verify the applicability of each source before using a value in a quote.
Input to record
An existing approved feed and explicit distance/time unit, plus the machine, power-mode, material, and test context for the source setting.
Output to carry forward
Equivalent linear feed units. No new material feed, controller percentage, or optical-watt estimate is generated.
Speed unit converter
Convert an existing approved feed without changing its physical speed. Always preserve the original unit. This converter does not choose a feed or turn a power percentage into optical watts.
Sources and scope
Content reviewed 2026-11-02. A documentation reference supports the stated method or data only; it does not approve settings on another machine.
- LightBurn 2.1 Material Test
Documents the two tested grid parameters, fixed base settings, explicit speed units, and preset export. No source settings are supplied by these pages.
- LightBurn 2.1 Shared Settings
Explains requested speed, explicit speed units, controller power settings, and device-dependent behavior. Controller percentage is not a measured optical-watt value.

| mm/s → mm/min | Multiply by 60. Arithmetic example: 100 mm/s = 6,000 mm/min. | Keep source units with the setting. The example is not a feed recommendation. | Unit arithmetic; LightBurn Material Test unit warning | Linear feed conversion only. | Exact conversion; no material setting selected. | 2026-11-02 |
| mm/min → mm/s | Divide by 60. Arithmetic example: 100 mm/min = 1.6667 mm/s. | Never copy the same numeric speed between per-minute and per-second controls. | Unit arithmetic; LightBurn Material Test unit warning | Linear feed conversion only. | Exact conversion before display rounding. | 2026-11-02 |
| Inches → millimeters | 1 inch = 25.4 mm; preserve the same time unit or convert time separately. | For example, 120 in/min = 50.8 mm/s. This is dimensional arithmetic. | Length-unit definition and unit arithmetic | Linear feed, not axis motor calibration. | Exact unit relationship. | 2026-11-02 |
| Controller power request | A controller percentage is a command setting. This page does not convert it to measured optical watts. | Record controller percent, tube/source identity, power mode, and the inspected test separately. | LightBurn 2.1 Shared Settings; shop/OEM measurement for watts | Only the recorded machine, source, and operating mode. | No watt estimate supplied; measured source required. | 2026-11-02 |
| Test context | The two Material Test axis settings vary across the grid; other base settings remain fixed. | Keep interval, passes, focus, air assist, material identity, and selected-cell evidence beside speed and power. | LightBurn 2.1 Material Test | Reusing a completed material test. | Documented workflow; shop validation required. | 2026-11-02 |
Reference workflow
- Match the job, material, machine head, and quality requirement to a row.
- Confirm the source, review date, and confidence before copying the value into a quote worksheet.
- Use a measured result or current OEM record when the row is marked as required or unverified.
