also at the accelerations. FF1 adds additional power to the motor at constant velocity, and can reduce error during the "cruise" phase of motion. FF2 adds additional power during acceleration, and should be used in VERY small amounts. Try starting with .001, and adjust for minimum error during the accel/decel part of the move. If in doubt, reduce the value to make sure you are not overdoing the amount of FF2.</td><td> |
