They are using cortex controllers
robotC
They also tether them together and all lights are green on controller and cortex
we've also tried programs like
Task main()
{
while(true)
{
motor[port3] =127;
wait1msec(1000);
motor[port2] =vexRT[ch2];
}
}

and

Task main()
{
while(true)
{
motor[port2] =vexRT[ch2];
}
}

Hmm... that sounds okay so far... although I'm not familiar enough with RobotC to consider any oddball settings in the compiler that might cause such a problem (there probably aren't any... but I don't know RobotC well enough to say for sure.)

And you have no problem getting the motors on Port2 and Port3 to run when you run them in auto mode, eh?

I don't have any immediate insights in to the problem... sometimes re-flashing the master code and re-downloading default code, essentially setting the robot controller back to factor spec is a good diagnostic.

Good luck, and do consider posting to VEXForum if you haven't done so already,
