This week I’ve etched/cut myself a ply control panel on the laser. In order to prevent excessive burning on the etch, I was conservative with the power settings, which initially looked quite nice (good fine detail). I have since oiled the wood as a finish, but the etching is now not directly visible in parts - but can be seen more when lit from the side. This might mean I will re-make the panel and use this one for further finish experimentation… however I’d like to know about other options.
Any advice on how to colour fill etching on wood? Anyone here done this before, and what works well and what does not?
