Sounds like your machine def is incorrect for the machine you're using, it needs to be configured to match your machine as well as your post.

On the "Cut Parameters" tab of the toolpath. On the left halfway down. Min. Toolpath Radius (0.1) is 2x stepover (0.05)598c50f9227a6_Capture1.PNG.ef56a00843d5aeba19374c94ad674fe3.PNG

                                                                                                                  

Note this shows Dynamic Optirough (3D), same rule of thumb applies to 2D highspeed which has no step up or step down options

Check  your source geometry (analyze entity). It could be a spline. If so try "simplify" under the  edit tab to convert to a line or create a point at each end and create a new line. It's a little difficult to diagnose just from the posted output. Why would you need 2d high speed to machine a simple linear contour?

You know, if you had called your reseller, chances are this issue would already be solved :) 

 

Look at the Misc Values page in the tree for the parameters
