i have a test file that is 10x10 square with tabs. While air cutting, the axis(s) stutters when it comes to the location where the tabs are located even though the z depth isn't at the tabs level yet. Through out the g code there are lines of code that are at the location of the tabs even though the z axis isn't at the tab level depth yet. If i run the file without tabs it's silky smooth. It's a really fine stutter but just enough to affect the cut quality. I've tried different post processors but the same result. My machine is a DIY build with chinese drivers etc. If i slow the cut speed down it doesn't stutter. Not sure why those lines of code are at the tab(s) point as they are not needed until the tabs are actually cut?
Maybe motor tuning?
Any help would be much appreciated!

A good start is to disable all of the CV settings, but leave CV on.
