Re: Can only get a single isolation pass around tracks #eagle #pcbgcode #etch

My approach is to use a small vacuum table with a sacrificial MDF top, leveled in-situ. No need to use an autoleveler - the vacuum ensures the FR4 is absolutely flat and tight to the surface and has no spring whatsoever.

Can consistently mill accurate 0.3mm tracks and isolation if required using a 30degree tool with a 0.2 mm spade tip. Cutting depth is set in pcbgcode to 0.2mm.
