Operating notes:

The clearPathAtBlk machine parameter (no. 124203)

allows you to specify whether the tool paths are

cleared with a new BLK FORM in Test Run operating

If points were output incorrectly by the postprocessor,

machining marks may occur on the workpiece. To

recognize these unwanted machining marks in time

(prior to machining), you can test externally created

NC programs for corresponding irregularities by

displaying the tool paths.

The control saves the state of the soft keys in non-

volatile memory.
