It comes up here as 6.08 and -6.08 as the extents.
Not a Mach3/4 problem as far as I can see.

We never have the time or money to do it right the first time, but we somehow manage to do it twice and then spend the money to get it right.

How do I check scaling
How do I check steps per unit


Position your machine at X0
Then MDI G50 G1 X6 F30
Measure how far the axis moved.
The G50 will cancel any scaling that may be in effect.

Your g-code shows a diameter of about 12” so the problem is with Mach 3 settings not V-carve.

I hate to be a pain but I have tried all that I know about CNC put to no avail. It seems that everything is have the size it should be, even when trying to cut threw a .76 in board and the setting is .78 in it only cuts down to .36 in not sure where to go from hear.

Thanks for you help.

Lets start with the basics. Use an one inch indicator and command a motion of one inch. See if the physical  motion matches the commanded movement.

MEASURE the actual axis movement with a RULER or DIAL INDICATOR.
Put a pencil mark on your table, position the spindle directly over that mark.
ZERO the DRO at that point.
MDI G0 X6.
Take your tape measure, or yard stick and measure how far the axis actually moved.....

I did this and it moved about 9 1/4 inches.
