WARNING:  Do not look into laser with remaining eye. Pages to do with the Laser Cutter:

Current Status - Partially working

  • Wood ¾” max
  • Circuit Boards (theoretically, not tested yet)
    • Either - Apply coating, laser etch off coating, etch off exposed copper w/ acid.

Operating the Laser Cutter

Scheduling time on the Laser

Please note: The Laser is only available to Hive13 members who have been certified on its use & care. If you are not in this group, you may be able to do so when members are present, but please get in touch ahead of time to prevent a wasted trip.

  1. Open your Hive13 Calendar (http://cal.hive13.org/ is a good start) and create an event.
  2. On the left hand side, select 'Add.. Rooms, etc.' and then 'Add 60W Laser Cutter'
  3. Select the 'Find a time' tab and navigate to the date and time you would like to use the laser, and make sure it is not shown as previously reserved on the calendar. You may schedule up to 2 hours at a time in advance. If no one else schedules time you can just continue using the machine - but we'd appreciate it if you would update your block later so we can keep track of usage.
  4. Save your event.

Do

  1. Check for water flow on startup
  2. Make sure exhaust fan is running
  3. Check for fires and put them out ;)

Don't

  1. Ever leave the laser unattended (see fires above)
  2. Turn off the “Air” button. That needs to be on to protect the lens
  3. Laser on Vinyl, PVC, Sintra (will produce corrosive and toxic gases)
  4. Cut metals (it won't work)
  5. Bump or touch the mirrors or lenses (will put the machine out of alignment or damage optics)

Software

LaserCut (Windows only)

  • This software will import files in these formats:
    • *.PLT (HPGL)
    • *.AI (Adobe Illustrator)
    • *.DXF (AutoCAD)
    • *.DST (Tajima)
    • *.CDR (Corel Draw)
    • *.BMP (Plain old bitmap, monochrome only) - and other common raster formats like PNG and GIF that will do monochrome
  • http://www.leetro.com/english/sale/35.html
  • Manual (pdf)

Printer Driver (Windows only)

  • Currently in beta, does vector only; raster coming later
  • Can print from most windows programs
  • Outputs a *.PLT file in the C:\output directory, which can then be imported into LaserCut

For more design software, see Design Resources

Calibrating the Laser

  • TODO: Add info about aligning the laser and mirrors.
  • The small cylinder meant for focusing the laser on the workpiece is 25mm in height and 25mm in diameter. It is made out of aluminum.

Troubleshooting

Maintenance

Please see the Service Log for technicians responsible for service/maintenance of the laser cutter.

Cleaning

Optics Alignment

Safety

  • Refilling the CO2 canisters
    • People love to play with them, so they need to be refilled fairly often.
    • Ian (iwilson/uid0) got them refilled at land, air, and sea in northern kentucky several times at a cost of $5ish/bottle. Not the cheapest.
