Cutting an "Index Hole"

I would like to create a “Index Hole” at the start of cutting my designs to facilitate matching up a design to the workpiece if a restart is needed. Would this be a simple as adding g-code to the beginning of the file? Maybe something like this:

G1 Z-1

Yes, but you may want to add a pause as well.

G1 Z-1
M1

In webcontrol, the yellow pause button turns to the blue resume button… no other real notification happens. HOWEVER, don’t use it until you see a new experimental (0.9335) or stable release (0.934) . I tested it before I posted and noticed that a variable was initialized incorrectly and would return the Z axis position to 0 after the pause.

And don’t forget to retract the bit again afterwards with something like G1 Z.25
