CV feedrate = +1

Increase your CV feedrate to the same value as your normal feedrate. Set the CV distance to 1 to 3 if you are in mm and to .05 to .15 if you are in inches.

Enter the desired CV feedrate in the DRO next to the CV feedrate button on the setting page, then hit enter.

wow!

That did it.

I cant believe that all i had to do was increase the CV rate.

What does CV stand for and what does it do?


Thank you very much.

The CV feedrate is the maximum allowed feedrate when Mach3 is "cutting corners". Mach slows down to this feedrate if it's lower than the programmed feedrate when cutting corners in constant velocity mode. If this feedrate is to low Mach behaves almost as in exact stop. A feedrate of 1 (inches or mm) per minute is VERY slow and makes the movement almost like exact stop.

You also may want to uncheck the "Stop CV on angles > x Degrees" under the Config > General Config menu page.

The phrase "CV" stands for Constant Velocity.
