Hey I have this program running. And I am wondering if Mach3 interprets G73 correctly. Drill is a .015 diameter, Pecking depth is set at .005, Minimum pecking depth is .005, Accumulated pecking depth is .0375, CHIP BREAK distance is .003 and no dwell. This issue is that it seems the chip break distance isn't being taken into account so then the spindle retracts about .1, pulling the bit out of the hole, almost like a G83. Is there another parameter I can manually input to force the Chip break distance or is this program correct and Mach3 doesn't jive? BTW, it works this way whether I am using a .010 drill bit or a 3/8" drill bit at any length of hole. Chip break isn't chip break.
