Contour preparation cannot process a noncircular program

Cause of error

The noncircular program cannot be processed by the contour preparation. Possible causes:
- The program contains contour elements whose length is extremely short (length < 1pm)
- The parameter "F effective as C feed rate" is set in the program and the C axis reverses direction during the program or its speed (briefly) drops to zero

Error correction
