Nasum A5 Pro Diode Laser Cutter

Fab Lab

This laser cutter can only cut through thin material. It’s a great choice for etching deep objects that don’t fit on our Omtech CO2 laser. There’s so many cuttable materials, but be careful of printing materials that can cause toxic fumes or fire. Since this is a diode laser and not a CO2 laser, it is unable to cut transparent or highly reflective materials such as acrylic. This machine also does not have as good of ventilation as our Omtech, so if you’re cutting something stinky or fume-y, use the Omtech. Ask staff if the machine needs calibrated.

Use & Safety Checklist:

  1. Always wear RED LASER EYE PROTECTION GLASSES when in view of the laser. Block direct laser to eye contact for passerby’s. Inform others not to look at the laser when it is operating without laser glasses.

  2. Do not leave laser unattended when in use. Be on the lookout for fires. Stop cut immediately if you see a flame. If you smell or see lots of smoke, stop cut immediately. Unplug machine to stop power.

  3. To adjust height, use a hex key to manually change laser focus. Laser should be roughly 3/32” away from the face of the cutting or etching material. Use a shim to verify height distance on each corner of your material.

  4. Verify material will not be moved or blown away by exhaust. Use paper-based tape to hold down material if necessary. Place tape where they will not come in contact with the laser.

  5. Double-check your settings before starting the cut job. Check Z-axis, location of material on x and y-axes, power, speed, and focus. Machine does not have a limit switch, so it will sometimes try to go beyond it’s x and y axis limits. If this happens, you will hear an awful noise. If this happens stop the machine by either unplugging it or stopping Lightburn Command. Failure to do so may cause bad damage to machine.

  6. Do not cut overly warped material. doing so may damage laser. If there is a small warp, place warp upwards (like a rainbow, not a smile).

  7. Do not attempt to calibrate without assistance.

  8. Don’t cut high-risk materials that can catch fire or produce toxic fumes, such as plexiglass.

  9. Locate nearby fire extinguishers.
