The progress slider is an indicator of the position in the current operation as well as the position of all operations. It can also be used to jump to a certain position in the toolpath by dragging the slider forward or backwards. Different operations are indicated in different colors and have a small black stroke in between.
The three bars underneath are report indicators and graphically represent the report result according to the operations above. The areas where a report happens are colored red.
First progress bar - Machine limits overrun
Second progress bar - Geometrical collisions
Third progress bar - Gouges
