Hi,
fine, then up the velocity, 21600 degrees per min is one rev per second, double it and see what happens.
When you have a rotary axis which has such wildly different numbers as these you can get into diffuculty.
If for instance you specify F=200 expecting the linear axes to travel at 200 inch/min then you'll be dissapointed,
the rotary axis will rotate at 200 degrees/min, less that one turn per min, and the linear axes will move glacially
slowly to stay synchronised.
In this circumstance the slowest axis determines the speed of all the rest.
Now imagine you you set F=20000 that would allow the rotary axis will go about 1 rev per second but the linear axes can
only go 350 inch/min and will that will limit the speed of the rotary axis to stay synchronised. Again its the slowest axis
that sets the pace.
