Software
We currently have LaserCut 6.0 installed on the computer connected to the Laser Cutter. Unfortunately LaserCut 6.0 requires a USB dongle to be hooked up to the PC at all times as a form of DRM. If you're running a personal copy you are restricted to a demo version (no saving - though there is a work around). Later versions (6.1+) have dropped the USB dongle requirement but can't communicate with our laser cutter directly.
Downloads
LaserCut 5.3 (Google Drive, Direct from Leetro) for Windows Paid, Demo
- The full version, but requires a special SenseLock USB Dongle to be connected to the PC running it or the software is limited to a demo mode (which is still useful for familiarizing yourself with the program). This version is needed in order to communicate with our laser cutter, as 6.1 doesn't support ours.
LaserCut 6.1 (Google Drive, Direct from Leetro) for Windows Free
- Not directly compatible with our laser cutter but has no USB dongle requirement, is fully functional aside from not being able to communicate with our laser cutter. Can still be used to prepare files for the earlier version of LaserCut (5.3). Both versions of LaserCut can be installed at the same time making this version a great option too.
123D Make (Direct from Autodesk) for Windows, Mac, iPad/iPhone Free
- A program for converting 3D models into pieces which can be laser cut and attached together to form a fully 3D model out of laser cut materials (example).
Pepakura Designer (Direct from Tama Software) for Windows Paid, Demo
- A program for converting 3D models into origami style pages which can be printed, cut out by hand and/or laser cut, then folded to form a 3D object (examples).
Resources
The Powerpoint presentation that is shown as part of the laser certification process (December 8, 2015), useful as a refresher once you've completed your certification.
TemplateMaker, a very useful Online tool for generating various custom boxes and shapes that can be cut on the laser.
Wolfie's SVG Puzzle Generator, exports a randomly generated puzzle in SVG format which can be converted to DXF and then laser cut out of something (in order to make personalized puzzles).
MakerCase, generates a proper box with the option to set the thickness of the material and pick which style of joints to use.
| It is imperative that you do a chlorine test on unapproved materials before working on them with the laser cutter. |
Specs
- 80-watt DC-excited carbon dioxide laser tube
- Water-cooled, with chiller accessible from the front
- Bed size: 1200 mm × 900 mm (47.2" × 35.4")
- Front panel of machine can be removed or folded down to insert pieces longer than 3' (though this can risk dangerous laser radiation exiting the machine, so be careful)
- Controller: Leetro MPC 6525A
- Can cut or etch up to 1/4" (6 mm)-thick light materials such as woods and some plastics in one pass, or thicker materials in multiple passes
- Cut kerf is approximately 0.3 mm (full width); you should measure it with your material if it's important to your project
| Do not cut any chlorinated synthetics (some types of plastics and rubbers)! The HCl vapors will damage the machine. |
Usage Notes
- Complete Laser Certification to learn how to use the laser. Training is offered about once a month.
- Perform a simple chlorine test on unapproved materials, as cutting or etching chlorinated materials damages the optics
- Consult our Laser Standard Operating Procedure
History
- Originally on loan for 6 months (ending August 2012) in exchange for Protospace performing repairs.
