I have a real basic shape that is a 2D outline of a screwdriver traced in Rhino. It was imported to X9 as splines, lines, and arcs. In MC I added a finger tab(half circle on either side of the handle with a small blending fillet). This is a shadow board for a toolbox drawer. So I have a basic pocket tool-path with a .25 end mill and back-plot and verify come out perfect. Unfortunately, the router cuts way out of the boundaries by the finger tabs and ruins the part. I've converted the splines to lines and re-chained the geometry. The simulation looks great, but again the code is wrong. I have never had a problem with this machine or post. So is this a post problem or MC programming problem? How do I go about fixing this?

Thanks,

Steve

BenK- Changing the control file did not make a difference.

Gcode- I checked my oldest files and they all use I &J for arcs.

Matthew- Is your backplot different than Gcodes?

I think I will completely redraw the outline in MC to make sure something was not corrupted from the Rhino geometry import.

So after trying many tweaks only one worked. I changed the pocket roughing choices from parallel spiral to constant overlap spiral and it worked perfectly. Does this mean there is something wrong with the parallel spiral routine? Thanks for all of your suggestions.

On a different note, what do you recommend for settings on the arc filter/ tolerance tab? The router does not get up to the programmed feed because of all the splines, short arcs, and lines. Or is there another setting to speed things up?

Try converting your splines to arcs to give better smoother motion. Edit Tab (just to the right of File), Simplify. Select all your wireframe with a window and it will convert everything it can to lines and arcs. Your router probably doesn't have enough look ahead to handle splines well.
