** Basically everything but metals and stuff that produces poisonous/corrosive gas.

** Why not metal? Short answer: Metal reflects IR too well to be cut with IR laser. Marking metals is possible, though.

The Machine

NOTE: Not yet in general use, content of operator training and best-practises are still being formulated.

First rules

  • Only operated by qualified operators, trainings will be organized with some regularity
  • Lifting the honeycomb must not be done alone (it's easy to break and costs 1800EUR to replace)
    • You probably don't need it anyway unless you're doing tiny things or fabrics.
  • Never leave machine unattended even for a moment when it is cutting (significant risk of fire)
  • Never touch the laser lens/nozzle combo.
  • Use only pure distilled water (akkuvesi) as cooling water, do not add anything else to the cooling water.

In case of fire

  • Small fire: open lid, try to blow it out.
  • If does not go out with blowing, use the fire-blanket.
  • If blanket does not solve the issue use CO2 extinguisher, leave the room, close the door and inform everyone at the lab.
  • If the CO2 extinguisher did not solve the issue: call fire brigade, inform the board.

Q & A

Start of operation checklist

  • Open the log form, fill in your name and the current time.
  • Use keys to turn on power
  • Turn on blower (switch)
  • If previous operator did not raise the bed to top ask for help from a superuser
  • Adjust bed for correct focus distance for your material

Cutting checklist

  • Did you change material ? If yes, re-check focus distance
  • Adjust head position, set origin (NOTE: the red helper dot might not be pointing exactly to the cutting point, use "pulse" to verify)
    • Make sure you know which point of your cutting job you should set as origin in the machine.
  • Use "border view" (sw) or "range" (panel) to verify bounding-box of cut.
  • Make sure blower is on (switch)
  • Make sure lid is closed
  • Start cutting, keep close watch on what is happening.
    • Risk of fire
    • Settings may need tuning
  • When done cutting wait 30-60 seconds for fume extraction before opening lid.

End of operation checklist

  • Remove honeycomb if installed
  • Raise bed to top
  • Turn off blower (switch)
  • Fill operation log (laser on time, work time)
  • Turn off machine (keys)
  • Clean up the bottom "drop area" in case you dropped something.
  • Finish filling up the log form and submit.
    • Failure to submit logbook will result in suspension of "qualified operator" -status.

Superusers

  • Aaro
  • Kremmen
  • Suovula
