hi to you all,
i hope you guys help me on the problem i am having with my CNC router
here is the problem , when i am machining sharp outer corners machine rounds of the corners related to feed speed , what i mean by that is ,faster i cut bigger the radius is, if i go slow than it cuts as it should, i tried to tune the Servo motors on tune page under config tab but no hope. if i give to much acceleration on either side of the profile machine gets too jumpy
problem some what rectifies though, on the other hand if i set more smooth acceleration problem gets worse.
help will be greatly appreciated   

maybe CV mode is turned on
