I often jog around with the arrow keys and the Page Up/Page Down buttons.
Those times when I want to ease my spinning cutting bit down to the surface level of a workpiece I lightly touch Page Down a few times. But when I am .03 or .02 inches away from the surface I cannot quickly enough bump the Page Down without the cutting bit plunging below the surface level. I want to be able to tell the machine to go down by a specified distance.
Is there some way in the Mach3 interface where I can simply type in G00 Z -.02 to command the machine to drop down .02 inches?
If so, where do I type this in? ~Or how else can I jog down by these tiny, specified increments?
