4.5.14 Show Interpolation Points
4.5.15 Set epsilon values for zero
The internal check of a value x for zero must be replaced by an examination for x < e due
to the inaccuracy of a floating point calculation. The size of the e-value may need to be
adapted (e.g. if 32-bit floating point values are used instead of 64-bit values, or when
importing a CNC program with limited accuracy). If you need to adapt the value, use the
Zero tolerance values dialog which appears when you select this command.
If this option is activated, interpolation points will be displayed on the basis of
a cycle of 100 ms; in other words, the tool positions will be indicated by small
grey crosses every 100 ms. This provides a means of approximately estimating
the velocity characteristics (fast = long intervals, slow = short intervals).

Note!
For standard applications, modification of the tolerance values should not be
necessary and should in fact be avoided!
