Changing a cycle call

You have called the desired cycle via softkey in the program editor, entered the parameters

and confirmed with "Accept".

In principle, variables or expressions can also be used in the input fields of the screen forms

instead of specific numeric values. In this way, programs can be created very flexibly.

Input of variables

Please note the following points when using variables:

● Values of variables and expressions are not checked since the values are not known at the

time of programming.

● Variables and expressions cannot be used in fields in which a text is expected (e.g. tool

An exception is the "Engraving" function, in which you can assign the desired text in the

text field via a variable as "Variable text".

● Selection fields generally cannot be programmed with variables.

can no longer be recompiled in the parameter screen.
