Constant Velocity problem with 4th axis

[tiwanacote]

Hi!!! When I use 3 axis everything goes good and not jerk movements and vibrations appears using "Constant Velocity" for angles > 170°. When I use rotary axis and Z axis working at the same time it goes bad, It seems to be working with "exact stop" mode. ¿What is the problem?? (I tried to change 4th acceleration settings and nothing got better.)

I don't think that Mach takes the 4th axis into account for CV mode, so there may not be anything you can do.

Thankyou Gerry!! I will confirm that Hypothesis
