Quite Sloppy gear box. Is a likely problem. I did try to place the wheel attach on the ground to try and eliminate the backlash and is why I asked about setting the max speed. (answered possibly by GeeTwo)
I did just see the Velocity mode in RobotBuilder and was going to play some with changing that. I was not aware this is new for 2016.
We are using Command Based Java
As virtuald stated and I found it was set to velocity.
Is there any other system controlling the motor?
No this is a fresh program with only the few components declared.
Some of my ideas posted where me brain storming for tonight to get the community input. Thanks for the kind words too.
Graphing is a great idea. I need to show them how to get the data in the smartdashboard displayed this way and see the power of the tool. I remember myself doing this last spring when I was testing the new PDP current draw of each channel. Thanks for reminding me to show this to them.
Shakes yes like over shoot. I could not see if it made a revolution. Graphing and trying to use the "setOutputRange" the others have mentioned should help identify this. We did have the encoder channels swapped and seen the motor run away with the error growing not closing.
Thanks to all lots of great ideas given and confirmed.
