Parameter Description
Backtrack Length The distance the dispensing tip travels away from the circle end point.
Range: 0–100 (mm)
Backtrack Gap The distance the dispensing tip raises as it moves away from the circle end point. This
value must be less than the ZClearance value for that point.
Range: 0–100 (mm)
Backtrack Speed The speed of the dispensing tip backtrack movement.
Range: 0–200 (mm/s)
Type Refer to “Example Illustrations of Backtrack Setup Parameters” on page93.
0 (Normal) The dispensing tip moves straight up for the height entered for
Backtrack Gap.
1 (Back) The dispensing tip moves backward at an angle for the distance
and height entered for Backtrack Length and Backtrack Gap.
2 (Square Back) The dispensing tip moves up and then back at the distance and
height entered for Backtrack Length and Backtrack Gap.
3 (Forward) The dispensing tip moves forward at an angle for the distance and
height entered for Backtrack Length and Backtrack Gap.
4 (Square Forward) The dispensing tip moves up and then forward at the distance and
height entered for Backtrack Length and Backtrack Gap.
Retract Distance The distance (in mm) the tip raises after dispensing.
Range: 0–50 (mm)
Retract Low The speed at which the tip raises after dispensing.
Range: 0–200 (mm/s)
Retract High After the tip raises the amount specied by Retract Distance at the speed specied by
Retract Low, the tip continues raising to the ZClearance at the speed specied by this
setting. The purpose of specifying a ZClearance is to allow the tip to raise high enough
to clear any obstacles it encounters on the way to the next point.
Range: 30–200 (mm/s)
