move_base/status never leaves status 1 (will not 'achieve' goal)

edit

I am using move_base with a large robot (2mx1m), diff drive configuration. When I send the robot a goal, it will reach the goal, but it appears it never gets within the goal tolerance, just barely outside of it.

I have increased minimum x and theta velocities, in place velocities, and even modified my motor controller driver to set a minimum power sent to each motor in case the /cmdvel message is too small. None of these solutions worked. Thanks!
