    Precix running with Mach3 gcode, problem in edges and corners

    We recently installed the Mach3MM to run on our precix. It seems that when the speed is high all the corners and edges tend to make a fillet and they do not follow the geometry.
    It can be an error in encoding ?
    It looks as if it makes a fillet on the edges or it starts lowering at z before it has reached the corner of the geometry.

    Do you have any clue?

    Thanks,

    Your acceleration is too low, and Constant Velocity is rounding the corners while trying to maintain the commanded velocity.

    Setting "Stop CV on Angles >" to 89 may help.
