B4 vs B6 Fiber Engraver
Working area flexibility
The ComMarker B4 offers two lens options, giving you a choice between a 110mm x 110mm or a larger 200mm x 200mm marking field. This allows you to switch between fine detail work on small jewelry and broader marking on larger metal tags or tumblers. The ComMarker B6 provides a fixed 150mm x 150mm working area. While this size sits between the two B4 options, it does not allow for the larger 200mm x 200mm field. If you need to mark larger items regularly, the B4 lens choice provides more versatility. If your work stays within the 150mm range, the B6 is sufficient.
Form factor and weight
The ComMarker B6 is designed as a compact, portable unit that weighs only 13kg. Its dimensions are 28 inches wide, 12 inches long, and 10 inches high, making it easy to place on a desktop or move between workstations. The ComMarker B4 is described with dimensions of 3.94 inches in width, height, and length, which appears to be a listing error for the unit size. However, it is also marketed as a 2-in-1 desktop and handheld machine. The B6’s specific weight and portable design make it easier to handle for users who need to move the machine frequently.
Auto focus capability
The ComMarker B6 features an auto focus system controlled via its touch screen. This simplifies setup by allowing you to adjust the focal distance quickly without manual intervention. The ComMarker B4 data does not explicitly mention an auto focus feature. It relies on manual adjustments or the included positioner and auxiliary holder for setup. For users who engrave different materials or thicknesses frequently, the B6’s auto focus saves time and reduces the chance of error. The B4 requires more manual attention to ensure the laser is correctly focused for each job.
Included accessories and lenses
The ComMarker B4 comes with two distinct lenses: one for 110mm x 110mm and another for 200mm x 200mm marking areas. It also includes a positioner and an auxiliary holder. The ComMarker B6 includes a foot switch, a type-C cable, a riser, and a placing helper. It does not list multiple lenses in its package. If you need to switch between small and large marking areas, the B4’s dual lens kit is a significant advantage. The B6 focuses on ease of use with its riser and helper tools but requires you to purchase additional lenses separately if you need a different field size.
Software compatibility
Both the ComMarker B4 and the ComMarker B6 support LightBurn and EzCad2 software. They also both operate on Windows 7/8/10/11 and Mac systems. This means you can use the same design files and workflows with either machine. There is no practical difference in software capability between the two models. Both support standard graphic formats like BMP, JPG, DXF, and DST. You can choose either machine based on hardware preferences without worrying about software limitations. The choice comes down to physical features rather than digital compatibility.
Which ComMarker B4 or B6 fits you
You need two marking sizes for varied jobs
The B4 includes two lenses, offering 110mm x 110mm and 200mm x 200mm fields. This flexibility lets you switch between fine jewelry details and larger tags. You get both options in one package without buying separate hardware. The B6 provides only a single 150mm x 150mm area, limiting your range.
You want a single fixed desktop workspace
The B6 features a dedicated 150mm x 150mm working area. It includes an auto-focus screen for quick setup and a compact 13kg design. The dimensions are 28 inches wide, 10 inches high, and 12 inches long. This fixed footprint suits users who prefer a consistent, ready-to-use desktop station over swapping lenses.
You prioritize auto-focus convenience and portability
The B6 model highlights an auto-focus screen, simplifying the marking process. It is described as portable with a compact size. The unit weighs only 13kg, making it easier to move. If you value quick focus adjustments and a lighter, more manageable machine for desktop or tabletop use, this spec profile fits your workflow.
