The Neje Laser Engraver DK-8-PRO is an awesome small laser engraver from China. Unfortunately, the supplied app is Windows only. There is an OSX App called DBeam available however some functions don't work with my DK-8 (movement keys), and I wanted a little more flexability over the image importing.
So, with a combination of the supported Hex commands (found from https://github.com/AxelTB/nejePrint - commands.txt), and listening to the serial port I wrote my own.
- Image importing
- Auto-resize
- Dithering or average pixel color settings
- Editing of imported image
- Real time progress preview of engraving image
It requires an OSX Serial USB driver - I used the one from here (working on OSX Sierra 10.12.1):
