Try downloading pycam. It's basic Cnc software that's easy to learn and play with. You can generate your own Goode to run.

Maybe you have 200 steps/rev stepper motors instead of the 400 step/rev motors. That would make yours seem twice the size...

Aaron is correct on this one. Quick way to check it is this way. I'll assume you are using grblgcodesender.

Type the following, ignore the comments
G20 G90 "inch mode, absolute coordinate"
G1 X1.0. "X should move just 1 inch"


If you move 2 inch, change the pulse/mm by dividing it by 2.
