Current Status - PARTIALLY WORKING
As of Oct. 6, 2013: The laser can cut material, but the red sighting laser is down. This makes it more difficult to line up cuts. See the (service log) for more information.
Certified with the laser? Want to get on the good side of the laser operators? See what you can possibly do to help on the Laser workstream on BetterMeans.
The Laser is only available to Hive13 members who have been certified on its use & care. To become certified, you need to take the certification class. Contact us about scheduling one at other times.
Note: The list of certified people is currently out of date and has not been updated in ages.
Only the following people are certified and permitted to fire the lazzzor:
- Chris Davis
- Paul Vincent
- Dave Menninger
- Tiffany Vincent
- Alicia Kravitz
- Ian Wilson
- John Stoughton
- Brandon Wooldridge
- Jon Neal
- Chris Hodapp
- Craig Smith
- Kris Sandrick
- Dave Myers
- Ben Dakin
- Cutting Area: ~12"x20"
- Tube Cost: $600 @ 3500 Hours
- Automatic Z Axis
- Travel Speed: 12" / minute cutting 3/4" wood
- 100% speed: 60" / minute (cutting thin materials)
For details on the different settings required for different materials, see Laser Settings.
For sources of materials to cut and engrave, see Materials Resources.
General material limits:
- Acrylic ¾” max
- Wood ¾” max
- Circuit Boards (theoretically, not tested yet)
- Either - Apply coating, laser etch off coating, etch off exposed copper w/ acid.
- Metal - Will not cut
- Must apply chemical to "etch". Does not really etch, chemical only bonds to metal.
- Can only do this to soft metal.
- Paper / Cardboard
Pay by the Minute
- $0.50 / minute for members, pay by the minute
Operator fee, pay by the hour
Details currently under discussion

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 on Fab Lab Mondays, but please get in touch ahead of time to prevent a wasted trip.
- Open your Hive13 Calendar (http://cal.hive13.org/ is a good start) and create an event.
- On the left hand side, select 'Add.. Rooms, etc.' and then 'Add 60W Laser Cutter'
- 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.
- Save your event.
- Check for water flow on startup
- Make sure exhaust fan is running
- Check for fires and put them out ;)
- Ever leave the laser unattended (see fires above)
- Turn off the “Air” button. That needs to be on to protect the lens
- Laser on Vinyl, PVC, Sintra (will produce corrosive and toxic gases)
- Cut metals (it won't work)
- Bump or touch the mirrors or lenses (will put the machine out of alignment or damage optics)
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
- 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.
Please see the Service Log for technicians responsible for service/maintenance of the laser cutter.
- 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.
