![]() Peter Smid has a great book on CNC programming, and it's even steered towards Fanuc, so you'll be in luck for reading it. You're not alone in getting the hang of cutter comp in machine programming. ![]() I always had trouble with magnetism in electronics. Although I'm not 100% certain, but still I do it out of practice, is I go in and out of cutter comp before and after any Z axis retract to clear move. ![]() Also any radii that the cutter will encounter along it's tool path has to be equal to or greater than the radii of the tool set in your tool offset library (H21) or you will get a G41 error. Cutter comp must be turned on and off with a move in either the X or Y axis or both. (Don't feel bad, it's tuff at first for all of us.) Other than what I just showed you above, the fact that there's a line that says G40M5 tells me so. I see there might be the need for more studying up on cutter comp. I see why you're plow-plow-plowing.)ĭear Jack. 21 (This coordinate is a hundred miles away from your start point. (Why is this line here? You're already at Z-0.365) Not possible.What CAD/CAM software are you using, or are you writing this off the cuff? (Which is fine also.) Here's your code. First thing I see right off is G41 activated in a Z move. ![]()
