X-Smoothness (Xtreme Smoothing™)

The X-Smoothness tab is the most advanced low-speed tuning feature currently available on any
microstepping drive. The benefits of low-speed smoothness are 1) reduced vibration, and 2) an
increase in torque, which was typically lost to vibration before the arrival of the Impulse drive.
Achieving this revolutionary smoothness is easily and quickly accomplished by following the
simple proced ure b elow. Note: the motor must be disconnected fr om its load while performing
Xtreme Smoothi ng™.

Adjusting X-Smoothness #1, #2, #3
Important: Whether using an IDC motor or a non-IDC (custom) motor, all six X-Smoothness
values (L1, L2, M1, M2, H1, H2) must be adjusted in the order described in the following
procedure. Note: Slider bars L1 and L2 are interactive, as are M1 and M2, and thes e interactive
sliders should be alternately adjusted until th e deepest null setting is achieved.
X-Smoothness #1
Recommended values for L1 and L2 have been pre-configured for IDC motors, but we
recommend that these settings be verified and adjusted if necessary by the following procedure.
If you are using a custom motor file, th ese values were calculated in the Advanced Motor Editor .
1. Press the Run Test button.
2. Move slider L1 left and right until the smoothest running condition is reached.
3. Move slider L2 left and right until the smoothest running condition is reached.
