LONGER Laser B1 20W engraver

The LONGER Laser B1 is a 20W diode laser engraver with a 450×440mm working area designed for hobbyists and small workshops. It handles cutting and engraving on wood, metal, acrylic and stainless steel using a 40mm fixed-focus lens and a 32-bit motherboard for stable operation.

Safety features and air assist

Flame detection and position protection stop the machine instantly if movement, tilting or ignition occurs. Limit switches on both axes improve positioning accuracy while a safety lock prevents accidental starts. The smart air pump is controlled automatically from the motherboard to clear smoke and keep the cutting surface clean.

Software and connectivity limits

The engraver works with LaserGRBL and LightBurn on Windows, Mac OS and Linux through the provided connection options. The 20W optical output and fixed-focus lens set practical limits on material thickness and cutting speed that users should match to their project requirements.

Questions about this item

How does the 32-bit motherboard control the air assist during a job?

The smart air pump is automatically managed through laser settings on the 32-bit motherboard, so it activates when the laser fires to clear smoke and keep the cut clean.

What are the exact frame dimensions I need to clear on my bench for the 450×440 mm working area?

The machine provides a 450 mm by 440 mm engraving area; allow extra space around the gantry for cable routing and the air-assist hose.

Which step do users most often miss when setting up the limit switches and safety lock?

After homing, enable the X- and Y-axis limit switches in the firmware and engage the safety lock before the first burn, otherwise the flame and tilt sensors will not arm.
