After program abort, show whether G61/G61.1/G64 settings are consistent with machine state at last executing motion prior to abort. This test runs and aborts a test .ngc program several times with various motion mode and blend/naive CAM tolerance settings. Checks are performed at various times relative to program execution: 1) Motion mode: Does stat buffer agree with programmed mode? 2) G64 tolerance settings: Does stat buffer agree with programmed P/Q args? (Only for G64, and only when these params are available in stat buffer) 3) G64 tolerance settings: Do programmed tolerance settings produce expected motion, as evidenced by samples taken during program execution? The .ngc program is aborted before ever reaching a G64 programmed at the end. This demonstrates a bug caused by motion and interp running out of synch, affecting LinuxCNC v. 2.7 and reported in Github issue #177. The fix will be introduced with Rob Ellenberg's state tags work, discussed in Github issue #134.
