Greg,
Sorry, I miss understood what you were asking.

No, Pcb-Gcode does not have that ability. It only drills holes with drills and if memory serves me, you cannot mill holes either. It will only allow arcs so if you want a round hole, you have to break that up into two or more arcs.

Understood but what I meant was that in fusion 360 you can tell it you have a 1/4" bit and if the hole is 1/2" it will output cnc code to cut a 1/2" circular pocket. In other words fusion does not treat it like a drill operation if the bit size does not match but rather routes a thru pocket the size of the hole. I know this is eagle and not fusion 360 and I assume the plugin is producing the gcode but wondered if it might have the same intelligence. If using the right bit one could maybe not have to change bits at all.

The program will ask for the proper drill size
(depending on your default drill table), but lets
face it, the program doesn't have a clue what you
actually put in the spindle!

So even if your gcode calls for X different drill
sizes, and you only have one and don't change it
out, it will drill the holes at that size.

Am I making sense?
