Hey guys,

I knocked out a simple test code for 3D. Its a funnel shape.

3dtest.txt

I can get it to run fine with Mach in simulation mode but on the machine it halts at line:

N750 G2 X805.793 Y703.765 I15.766 J2.607 F3000

No error message and the cnc isn't in estop. Its like Mach gets to that part and decides to halt and go no further.

I've tried lowering feeds and switching to from G90.1 to G91.1. That did fix some problems with the initial contour roughing but doesn't do anything for this.
