I'm using 0 mm pocket allowance
First make sure your machine is adjusted to move 100 mm (or whatever) when the code calls for such a move. You will have to consult your machine instructions or the manufacturer for detailed ways to accomplish this.
In running a pocket, the software will generate g code that directs the center of the tool to a path that is half of the diameter that was stated for that tool in the database...away from the pocket vectors. If the tool is described as 16mm, and no allowance set, the tool center will follow a path that is 8mm away from the pocket vector. If the tool is truly 15 mm (instead of the 16 mm stated in the database), for example, the toolpath will still be 8 mm away from theoretical pocket vector, and the pocket will be machined by 1mm small per wall, or 2 mm across. You can narrow this down by measuring your tool diameter; or by cutting a simple groove in you material and measuring the width. The actual material you are using will also affect the size of the cut.
Now having said all that, if you want the pocket larger, you will have to go back to VCarve Pro or whatever software you have, and make the pocket bigger on the design...or if the tool diameter measures as something different than that described in the tool data base, you would correct that. And in both cases, regenerate the toolpath.
