I am in the process of building a piece out with a series of holes predrilled with my hand drill. Unfortunately, the spade bit did not remain centered and drifted laterally and vertically. So, now I am trying to correct the issue, even if the hole is now enlarged… and no, I cannot discard the part and start over; it is actually the CNC work surface. My idea is to use my CNC router to correct the issue. Since the hole exists of some sort, I would somewhat center the end mill bit in the deformed hole and then proceed to mill the hole by performing an inside cut, thus rounding up the hole.
The problem is when I use Inkscape, the home position is not at the center of the hole but is offset. How can I get the home position at the center of the center of the existing hole?
