Warning

Using a non-zero JerkPercent increases the maximum deceleration above the user-specified average.
If your system can’t handle the higher peak, you risk overshoot or excessive load. The relation between average deceleration and maximum deceleration is:

\[ Maximum Deceleration \;=\; \frac{decel}{1 - \bigl(jerkPercent \times 0.005\bigr)} \]

decel: the requested (average) deceleration value given in the MoveSCurve command.
jerkPercent: the percent of time with non-zero jerk (0–100) given in the MoveSCurve command.
Maximum Deceleration: the resulting peak commanded deceleration.
