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
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.
