Post a screenshot from Mach3. That will tell you if the machine is missing steps. I'm pretty sure that's what you're seeing.
You can also post the g-code and I'll verify if it's correct.
Technically, there's nothing wrong with the .dxf file. However, it's not perfect, at least for CNC use.
One all the closed shapes are 3D polylines. Not all CAM programs will support those entities. Note that they are not draw in 3D. They're just drawn with a linetype that's capable of being drawn in 3D.
Two, all the shapes are closed, which means the edges between closed shapes (just about all) get cut twice.
I'm not a big fan of using Sketchup as a 2D CAD program, but I know some people do and it works fine for them.
Here's a shot of the g-code I created from your .dxf in Mach3.
