Re: Newbie questions???????

To tell the operator the hole depth use parenthesis to make a comment.
Comments will show up in the status bar on Mach 3. For ease of
programming I would just run the program on single stop. On a
prototrak feed moves (G1) are done continuously while rapid (G0) moves
are made in a single block fashion. In mach3 you can make a M code to
switch between the two styles.

Ex.
TXM6 (.156 Drill)
M100(Switch to single block)
G0 X1. y2. (Drill to Z-.1)
X2. (Z-.1)
X3. (z-.5)
M101 (Turn off single block)
.....
