Hello

           I have a problem running multiple rotary motors simultaneously in a rotary arm of 3 degrees of freedom. I've attached a file with the assembly and the motion study. In the motion study, I specified when motors should start and end, however, at certain points when I want two motors running, the next motor starts when it should but the previous motor stops immediately. I'm able to run multiple linear motors simultaneously so i'm not sure whether its because I specified my mates incorrectly or some other error.
