Machine
Stepcraft DL445 laser extension to the Stepcraft routing machines.
Setup Fusion 360
When doing laser cutting/engraving, you need to setup the laser tool within Fusion 360. To do this, go to your tools library and add a new tool. In the window, select “Laser cutter”. For the DL445, the following settings can be used:
Tab Cutter: Nozzle diameter 0.1mm, Kerf width: 0.1mm
Tab Cutting data: Cutting feedrate 600mm/min
Tab Post Processor: Length offset 1, Diameter offset 1
All other settings can be left as is.
To use the laser, you should create a 2D profile toolpath as shown below.
Laser parameters
Different materials requires different laser settings in terms of feedrate and laser power. In the table below you can find the settings I personally like to use. Note that this applies to my Stepcraft DL445 3W laser.
| MDF | |
| Feedrate (mm/min) | 1200 |
| Laser power | 50% (M10Q127) |
| Acrylic (painted) | |
| Feedrate (mm/min) | 600 (too high will engrave too less of the painting) |
| Laser power | 50% (M10Q127) (too high will melt too much painting) |
