I agree with Joe.
So from the OP, it appears that you are using a 500 pulse encoder mounted directly on the motor shaft? Do you have any gear box before the wheels and what is the ratio? What size wheels? Assuming a 5:1 gearbox and a 4" wheel (~12.56 circumfrence) would give distance resolution of 0.005" Is that really what your accuracy requirement is? I recommend double checking your requirements.
