All you need to know to be able to do greyscale while laser engraving (photo engraving)
- You must check if your board supports dynamic PWM output (not all 3D printer boards and CNC board support that option).
- Check if your firmware supports dynamic PWM output (Marlin firmware does not allow, GRBL 0.9 does not allow either).
We suggest using a lightburn software for laser photo engraving.
To make a proper photo engraving you need to setup a few key parameters in Lightburn.
- Check your firmware
- Setup proper
- Max power
- Min power
- Image mode
