I sorry to say that i am having trouble understanding you too.

But from the little i picked up, i think your problem is compensating for the diameter of your tool.

Say you cut a 100mm x 100mm square and your gcode looks something like this.

F300
G01 X100
G01 Y100
G01 X0
G01 Y0

This will move the center of your cutting tool drawing a 100mm square.
Now if your tool measures... say 10mm in diameter... well your 100mm square will become a 90mm square.

You need to compensate for the tool diameter in your gcode. if you are writing your gcode by hand, then compensate by hand, otherwise any descent CAM software will do it for you.

Hope this is what you are meaning.
Regards
Fernando

Hi! My name is Julio and I've adopted my late father's nickname: "Don Faso" . He was a humble man with a big, noble heart and appreciated by everybody all over the city. In Puerto Rico where I come from, as well as in other Hispanic countries, the title "Don" is for a very respectable mature person of any social class. We don't follow the Italian meaning of it. I am disabled with traumatic brain injury after being a teacher in P. R. and the U.S. for 18 years. I am barely starting with CNC and it's an uphill battle for me because of my limitations. I am commited to doing it to help the family's budget and help me build an R/C flying model in foam of a circular wing airplane I want to test and patent. I need help understanding what the Machsupport website says that for Mach 3 to be supported in a laptop with a parrallel port (that's all I have and can afford) it has to use one of the external controllers in their PLUGINS section. If that's the case, which is the best controller for a Dell Latitude D630? I'll appreciate your help so very much!!!

Don, you may get away with using the laptop with the parallel port, some work some dont, try it and see. Not sure on the specs of that laptop you have though, if its under a 1Gig processor you may struggle.
 I personally would recomend the SmoothStepper if you decide to go the external hardware route but again there is no 100% guarantee your laptop will work but I have not heard of one so far that doesnt work with the SmoothStepper.
