If the encoder is functioning, then it should work "accurately".
The only other bit of information you might want to check is
for "cogging", also known as torque ripple and velocity ripple.
You can use one D cell to run the motor very slowly. If the rotation
is smooth, with no hesitation, then it probably will work fine in
a CNC motion control application, assuming the torque produced
is sufficient.
