basically you use a servo configuration where the encoder based real position and commanded position from the trajectory
go into a PID loop and the output of the PID loop drives the step generator in velocity mode, This arrangement simulates
a velocity mode servo with the step motor. Starting PID loop tuning for this configuration is FF1 = 1.0, with some small P term to correct for errors
