This post is part of the tools series.
This is the second part in the series on the tools I use. Tools that are surprisingly useful, tools that are not that obvious to find. Today: how to calibrate the CNC axis without actually cutting anything ? Use a test indicator ! How to hold the meter steady though, ? Attach it to the frame of your router using the power of magnets ! Sample item on Amazon here [affiliate link warning]
Despite being attached to the frame by its back instead of the bottom it still holds beautifully.
