Those gouges in what would otherwise be straight lines has nothing to do with CV. My first guess is the resolution of the X and/or Y axis is very low. How many steps per for each of those motors?

I did not look at your Gcode file but from the screen shot I can see it is well below acceptable. Why so many lines of Gcode for such a simple shape?

;D If you could see the things I have in my head, you would be laughing too. ;D

when i run the old"Cv tuning wizard" that mistake disapire and the hexagonal work perfect
only problem is that the speed on corner are very very slow ,because slider stack on left side  as this  topic subject
**that many lines are only the corners ,because this shape is create by the cad software that make the corner with external radius when you run the tool with diameter outside compensation

Ok, then download and use the CV tuning wizard I updated and posted earlier in this topic. But be careful what you wish for. The old wizard limiting your corners to "very very slow" is helping your tool path far more than populating the CV feed rate table with either wizard. In other words, you are benefitting from a bug in the wizard that slows your machine way down. Try running the CV distance tolerance wizard with a resolution of .010 and lower the feed rate of your Gcode to very very slow.

I think optimizing your CV feed rate table using the CvDistTolerance wizard brings to light problems with your machine. It's kind of like having a flat tire on a car and blaming the rough ride on the gas pedal because it is smooth as glass as long as it is sitting still but every time you give it gas it starts bouncing. Check your flex, backlash, motor tuning, etc.

All I can say is I have tested it with almost decent Gcode (the last file you posted). The CvDistTolerance wizard does exactly what it is supposed to and the tool path reflects it. I have attached 3 screenshots. The first is with tolerance at 100.00. The second and third is with tolerance at 1.500. The smaller the tolerance the closer it runs to the exact path as the pictures clearly demonstrate it is doing.

There are a lot of things that will cause bumps in the lines that would otherwise be straight. The only thing I am sure is not the problem is Mach4 software.

i attach my mach profile maybi its because i use fast movement  ... i dont know
but  one thing is ,that i not talk about corner ,corner small problem
please look at my previews screen shot , ital about the straight line itself, have many wave on it ,on mach simulator
