Hi, i have probleme with the size that machine cut( .125"  larger on 2" square) . I've double check if  the machine move exacly  the right distance , its ok ,  I've make the draws by autocad,so i'm sure that he have good size , and the g-code i'm think its ok.  I use Sheetcam to post g-code . I make 1 cut with offset (set on sheetcam)  and a another cut with no offset . The size of the 2 part stay the same  .i think  mach3 doenst read the offset

Anyone can help me please
