Test Run and Program Run | Graphics
The control saves the state of the following soft keys in non-volatile
memory, even after interruption of the power supply:
Collision monitoring
Movements at rapid traverse
Workpiece blank frame
Workpiece edges
Transparent workpiece
Workpiece in color
Operating notes:
The available functions depend on the selected
model quality. You can select the model quality in the
MOD function Graphic settings.
With the machine parameter clearPathAtBlk
(No. 124203), you can specify whether or not the tool
path in the Test Run operating mode is cleared with
a new BLK FORM.
If points were output incorrectly by the
postprocessor, then machining marks 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 the display of tool paths.
A powerful zoom function is available in order for you
to quickly recognize the details for the displayed tool
paths.
The control displays traverse movements in rapid
traverse in red.
