The other day I bought some engraving tools for milling Printed Circuit Boards (PCB).
As can be seen, I’ve set up an Auto zeroing system using crocodile clips on the work surface and milling tool. Once the milling tool tip comes into contact with the work piece, this triggers an input.This allows the system to zero itself and do a much more accurate reading. This is a really rough video, just basically demonstrating where I am with it, after the project has been sat idle for a couple of months. It also demonstrates why you shouldn’t use tape to secure your work piece! So the next job will be be making a special PCB holder.
