As in left a straight line in the inside? I've never had this happen. I have a program that makes circular bores, either completely carving the interior or trepanning out the slug and then doing a finishing pass. Either way, it does the circle in quadrants. The reason for this is partly historical, the original version of the program was written for the Allen Bradley. The other reason is the one that bores out the entire hole expands by offsetting each quadrant a little.
So, anyway, using my program that never does more than about 90 degrees (it can be a hair more than exactly 90 when expanding the spiral) I've never had such a problem. I make lots of panels where all the round holes except the smallest are bored-out with one tool size. I have to admit I'm not using the very latest EMC2 version on my Bridgeport. Are the following error limits tight on that machine? Is it possible a chip jammed the machine and no following error was caused, so it just completed the program as best it could, and the chip then fell out when the axis reversed?
