i have a general question on PCB drilling.
when i generate gcode for drilling with eagle-cad and the pcbtogcode plugin i get two drilling files, one for top, one for button.
Does it make sense to drill both sides and meet the holes in the middle of the board for better edges? When i drill them just from one side the copper stands off at the botton side. or should i just play around with the spindel-speed and feddrate
