Just a thought, is there a chance you have an imperfection in your head assembly or the kinimatics, that is causing your cut to be offset slightly? In other words are the pieces the same size if you cut them out in the opposite direction?

It appears that when the fibers are cut I get a small amount of expansion so the part to be inset ends up just a little too large, even though it is cutting exactly the same size as the base in which it is to be inset. I was looking at tool compensations to see if I can adjust the tool path by a very small amount (0.005" - 0.01") to make the inset part just a little bit smaller, following the example here: http://linuxcnc.org/docs/2.5/html/gcode/tool_compensation.html The pattern runs entirely CW, so G41 should compensate in the appropriate direction. The example shows: G10 L1 P1 R0.25 Z1 Does Z1 have any meaning in compensating only in X and Y? If I set the compensation for the entire file, do I have to deal with individual lead-ins? And of course, is there an easier way to accomplish this? Thanks, Eric ------------------------------------------------------------------------------ Attend Shape: An AT&T Tech Expo July 15-16.
