Thanks for the input!

Well, I got better results now by trying this: Coast(Port); Wait(50); Off( Port ); Wait(300); SetOutput( Port, 0, 0, OutputMode, OUT_MODE_BRAKE + OUT_MODE_MOTORON + OUT_MODE_REGULATED , UpdateFlags, UF_UPDATE_MODE + UF_UPDATE_SPEED, RegMode, OUT_REGMODE_SPEED ); Still a little jitter at high power, ...

John, I did a search for your posts, but did not find one with the ramping code.

Thanks,

Thanks, do you have a link to that thread? Unfortunatly, the way my son built the arm, this motor needs > 75% power.

OK, I think I added the PID values, and used various combinations of PID_0 to PID_7 values, but do not see any difference. See this youtube video of the problem http://www.youtube.com/watch?v=-5sBj8hgPq0&feature=youtu.be [youtube]http://www.youtube.com/watch?v=-5sBj8hgPq0&feature=youtu.be[/y...

Thanks, I am a total newb. How does one set the PID value(s)?

My Son is building a robotic arm for a science competition. We need to get a hard brake on the motor. I found the example below to brake and hold the motor arm in place. However, when I execute the code, the motor does not stop completely. It actually does a small back-and-forth rotation and then st...
