A few pictures of a test run trying out isolation PCB routing. GCode was generated using the PCB-Gcode script for Eagle, using the backplane board from my 6502 project as input.
Part way through the run I noticed that the mill was slightly out of alignment on the X-axis, this was causing shallow track cuts which got progressively worse the further along the X-axis the program went. A quick adjustment of the gantry seems to have fixed this but some further testing is required. I also need to tweak feed rates and cut depths, but the test went very well!
