Hello all, I'm a CNC newbie who needs some help.

I have a small hobby router kit I put together w/ the trial of Mach3 and educational Fusion 360 for CAD/CAM, I found a piece of scrap wood 4x4x1 or so stock and wanted to use it to practice generating my own toolpaths (got the sample .nc toolpaths that came w/ my router to work). Generated a simple part with channel through the center in Fusion. When I ran it, it was moving in a small area, I believe the gcode is running correctly as the coordinates matched it on the Mach UI. The problem is the scaling of my coordinates... when I jogged the tool to center of my piece where I am trying to cut a channel through it the coordinates were 15 or 30 (which isn't conversion to mm) and larger than my stock dimensions.

Any clue what could be causing the coordinate scaling problem and if the solution would be in Fusion, Mach3, or either?
