That's a strong clue that you have your wheels swapped. A robot with mecanum wheels in a perfect square wouldn't be able to spin at all. With a more typical rectangular configuration it will manage to spin, but with obvious reluctance. With the robot turned off, can you push it by hand and make it spin easily? If so, that confirms the problem as swapped wheels.

The pattern of rollers touching the floor should be in an "O" or "diamond" configuration. They will look like an "X" from above.
