Lots of experimenting in this episode, as I switch things up, and look using a etch based solution, with the CNC’s laser being used to create the etch resist pattern.
My current plan is to try use the CNC’s laser where ever possible, as I believe this will provide the most accurate and consistent result.

This is the fourth episode in a series where I am challenging myself to make the best possible DIY PCB’s using commonly available low cost CNC technologies.
