Plotter Cutter Bit

Here are some notes on using the CNC machine with a plotter cutter blade. For $17 I got a blade holder + 5 pc 45° blades for Roland liyu GCC cutting plotter vinyl cutter off eBay.

Below is the eBay pick and all I had to do to fit it in a 11-12mm collett was to turn down the wider knurled knob.
