In this case abs[tempz] * tan(2) looks great, just a hair over 40 thou of outward expansion in .6" of z. And to cut the gears central hole to the same taper, remove the 'abs' and reverse the mill_rad compensation to put the cut on the other side of the bit & change the g2 to g3 so it remains a climb cut. > just draw the picture of what the machine must do, and put your variable > names in the picture. > It will soon get clear. > > > j. > > PS. > I do not see why linuxcnc wants to hang on you piece of code, unless it > is as > Jon says that the stepper thread is eating all of the cpu time. I have seen this effect when the subroutines get all piled up, 3 deep before. But this is the worst I've had it behave. I can't do a lot about the subroutine depth, but the above line of code should simplicate the heck out of the rest of it since we can derive the depth related additive in one operation per G2-3 cut. That has to help. Thanks, a lot Jan, I appreciate it. > cheers. Cheers, Gene -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
