A link to how you built the cnc machine would be good. Also your letters look quite grey in colour, i think its possible you are engraving too deeply and going through the white coating (under the black top coat)mto the grey colour of the key . just a thought and don't know if i am correct on this but thanks for posting the video
Thank you for watching! I followed this post www.thingiverse.com/thing:3521286 on Thingiverse for building the small CNC. There is some sort of clear coating on the keys, by engraving it is not shiny anymore in the spot where the laser was. The keys are made of black plastic, so they are not grey inside.
