Things to make
box generators
BoxMaker
Link: http://boxmaker.rahulbotics.com/
This script has been tested to created a 50mm cube from 7.5mm clear acrylic, here are the settings used.
Interestingly, the cube had an internal width of 42mm and external width of 57mm - this was due to the DPI, the generator assumes 100 DPI, the Inkscape default is 90 DPI. Once set correctly, it is highly accurate.
| Units | millimeters |
| Width | 50 |
| Height | 50 |
| Depth | 50 |
| Material Thickness | 6.5 |
| Notch Length | Auto |
| Cut Width (Kerf) | 0.1 |
Boxer

This is untested. May work well with wood but will not play nicely with the 7.5mm acrylic. burn baby burn the fun part
Cutting
| Setting | With film | Without film | Without film (alternate) |
| Power (mA) | 20mA | 18mA | 20mA |
| Speed (mm/s) | 2.5 | 2.8 | 2.8 |
| Bed height (mm) | 61 | 61 | 61 |
Etching
Undocumented. Though many have had great success with surface etched designs especially on wood and acrylic.
Help / issues
We've found that if you try cutting with the underside's protective film removed, you will find 'swirl marks' after cutting. These are caused by the heat/smoke being extracted from the cut. To fix this, simply leave the protective film in place until you are finished cutting. Laser swirl marks.jpg
