I have been tinkering with the isolation settings on my PCB layout and I'm getting a weord result with some settings. Maybe someone here can shed some light on what is happening.
Here is a picture of my PCB layout in Eagle notice the USB connector hangs out over the PCB mill outline. This is where I'm thinking the problem starts.
Notice the PCB-Gcode output it adds an etch line outside the milling outline. It only does this when I set the: Isolation-->Maximum > .01. Under .01, I do not get very much isolation but it does not add this extra milling.
Doing singles on scrap pieces of PCB this is fine however if doing a dual board side by side I then have to waste the extra PCB material.
It would be nice if when determining the gcode, pcb-gcode would do a check for the milling outline and stop if there.
