Code running slow

[BradAMiller]

The commands are run by repeated calls to Scheduler.run(). Make sure that it's being called in the teleopPeriodic() or autonomousPeriodic() methods in the main robot project like this:

    public void teleopInit() {
	// This makes sure that the autonomous stops running when
        // teleop starts running. If you want the autonomous to 
        // continue until interrupted by another command, remove
        // this line or comment it out.
        if (autonomousCommand != null) autonomousCommand.cancel();
    }
    /**
     * This function is called periodically during operator control
     */
    public void teleopPeriodic() {
        Scheduler.getInstance().run();
    }

Also you can verify that the commands are running by writing the Scheduler instance to the SmartDashboard as shown in this web page:
