Favorite board

[Shabby J]

Make sure your field is sitting down flat onto it's frame rails. Push down on the field in the corners especially and around the edges to make sure it is seated flush. When my board's vibrations change, it has been due to this.

Also, take notes and mark down the set up that works best for you. Note which of the two wires is attached to which post on the controller and which "direction" the button is set at too. It makes a difference. Try different combinations of wire and motor direction set ups, then mark or record the best set up.
