ATC + tool setter sequence - repeatability test

This is a quick test of my M6 automatic tool change routine with automated tool length measurement using a tool setter. The G54 origin is the starting and ending position (on the dial indicator), and a simple G-code file does two tool changes and return to the work origin after each. I don't do any 'offline' tool length measurement or store any offsets in the tool table - this automated tool length measurement is the sole mechanism for setting tool length offsets.
