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.
Start of operation checklist
- 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.

Q & A
- Materials?
- See http://atxhackerspace.org/wiki/Laser_Cutter_Materials
- https://tampere.hacklab.fi/viswiki/Laserleikkuri
- 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.
- Cutting area: 1600 × 900 mm with through feed.
- File formats
- Adobe Illustrator
- DXF
- BMP/JPG
- "ISO" Gerber
- SVG is NOT SUPPORTED.
