Who it fits

Key specs explained

Laser Type: Fiber (1064 nm)

This machine uses a fiber laser source that emits light at 1064 nm. This wavelength is ideal for marking metals and some plastics. It provides high contrast and deep engraving on materials like stainless steel, aluminum, and gold. You get clean, permanent marks without needing assist gases. It is not suitable for wood or acrylic, which require CO2 lasers.

Laser Power: 30W

The 30W power rating indicates the energy output of the laser source. Higher wattage allows for faster engraving speeds and deeper penetration into hard metals. You can mark anodized aluminum or cut thin metals more efficiently than with lower power units. This power level suits professional marking tasks and high-volume production jobs requiring consistent depth and speed.

Working Area: 110 x 110 mm, 200 x 200 mm

The unit includes two interchangeable lenses offering different field sizes. The 110x110 mm lens provides higher resolution for fine details on small items like jewelry. The 200x200 mm lens covers a larger area for bigger tags or tumblers. You can switch lenses to balance speed and precision based on the specific size of the object you intend to mark.

Engraving Speed: 0-15000 mm/s

The galvanometer system supports marking speeds up to 15,000 mm per second. This high speed reduces processing time for repetitive patterns or large text areas. You benefit from increased throughput when producing batches of identical items. Faster speeds are particularly useful for industrial applications where time efficiency is critical for maintaining workflow productivity.

Software Compatibility: LightBurn, EzCad2

The machine works with LightBurn and EzCad2 software, giving you flexibility in design workflows. LightBurn offers a user-friendly interface for Mac and Windows users. EzCad2 is the standard industry software for fiber lasers. You can import various graphic formats and adjust parameters easily. This compatibility ensures you can use familiar tools or switch to specialized industry-standard programs as needed.

Build Quality And Physical Design

According to the listing, the ComMarker B4 30W combines desktop and handheld functionality. This dual-mode design allows you to use the machine on a workbench or hold it for larger items. The unit weighs less than traditional industrial markers, making it portable. You can move it between stations without heavy lifting equipment. The compact form factor suits small workshops or home studios where space is limited.

The device includes two interchangeable lenses. You get an 110x110 mm lens for detailed work and a 200x200 mm lens for larger areas. This flexibility lets you switch tasks quickly without changing hardware. The listing notes a maximum marking speed of 15,000 mm/s. This high speed reduces production time for repetitive jobs like serializing tags or marking jewelry. The galvanometer system ensures precise positioning at these speeds.

Safety features are built into the design. An emergency stop switch is included for immediate shutdown during accidents. The machine meets Class 1 laser product standards according to IEC 60825-1. You must still wear the included 1064 nm goggles when operating. The foot switch allows hands-free control, keeping your focus on the material. The unit supports Windows and Mac systems via LightBurn or EzCad2 software. This compatibility simplifies integration into existing workflows.

Setup And Daily Operation

The ComMarker B4 30W requires minimal setup for daily operation. You connect the unit to a standard 110V power outlet using the included adapter. The package provides a USB drive with EzCad2 software, which serves as the primary control interface for Windows systems. You can also install LightBurn for macOS or Windows users who prefer that ecosystem. The machine supports BMP, JPG, DXF, and other common graphic formats, allowing you to import designs directly into the engraving software.

For everyday use, the dual-lens system is central to your workflow. You switch between the 110x110 mm and 200x200 mm lenses depending on the size of your project. This flexibility lets you handle small jewelry pieces or larger tumblers without changing the machine’s position. The included positioner and foot switch streamline repetitive tasks. You place your material on the positioner and use the foot switch to start and stop marking, keeping your hands free for safety.

The 15000 mm/s marking speed and 20-60 kHz frequency enable rapid processing of metal and painted surfaces. You benefit from automatic lifting and an emergency switch, which enhance safety during long sessions. The included 1064 nm goggles are essential for eye protection when operating the Class 1 laser product. You can engrave stainless steel, aluminum, gold, and silver with precision down to 0.01 mm line width. The system’s compatibility with both desktop and handheld modes means you can mark fixed items on a bench or move the head for larger objects, adapting to your workspace constraints.

Before You Buy This Fiber Laser

Before you buy the ComMarker B4 30W, verify your workspace and power needs. This unit requires a standard 110V outlet and includes an adapter. You must check software compatibility. The machine supports LightBurn on Mac and Windows, or EzCad2 on Windows. Ensure your computer meets these system requirements before ordering. Note that the package does not include roller accessories. If you plan to engrave cylindrical items like tumblers or pens, you will need to purchase a rotary attachment separately. The listing confirms the B4R-30W+rotary option exists, but verify if it is included in your specific selection. Upkeep involves regular cleaning of the lens and ensuring the emergency switch functions correctly. This fiber laser suits metal marking tasks better than CO2 models for this category. It fits well if you need handheld flexibility alongside desktop precision. Always wear the included 1064nm goggles during operation. Check the included material package for test plates. This approach ensures you understand the full scope of ownership before committing to this specific fiber laser engraver.

Check before you buy

• Confirm 110V power outlet availability.
• Verify Mac or Windows compatibility.
• Check if rotary accessory is included.
• Ensure you have safety goggles.
• Review supported graphic file formats.
