Tape Feed Setting Values

WARNING: Editing the Tape Feed settings with incorrect values may lead to inaccurately scored shots.




Default Value

Millimeters per Second

The speed of the tape feed motor, measured in mm of tape advance per second.

15.0 mm / second

Pause after Advance

The amount of time, in seconds, the scoring algorithm will pause after the tape feed advances.

3 seconds.

Calculating Millimeters per Second

The calculation of Millimeters per Second is done by advancing the Tape Feed 10 times, an expected 16mm each time. The actual distance travel is then physically measured and inputted, resulting in the new updated millimeters per second.

1.Cut off any existing tape feed from the Target.

2.Click the "Run Test" button.
The Tape Feed will pulse 10 times.

3.Once the Tape Feed stops after the 10th pulse tear off the tape that was feed through the target. Measure, using millimeters, the amount of tape that was feed through. The expected value is 160mm.

4.Input the actual distance traveled into the form and hit Calculate.

5.Repeat the test if the actual distance traveled is more than 165mm or less than 155mm.



Pause After Advance

When ever the tape feed runs, being a mechanical motor, will cause vibrations within the Target. Before the Athena Target starts to score shots again it must pause after each tape feed run to allow these vibrations to settle. If the pause is too short, false positive shots may get scored. If the pause is too long, it may cause the next real shot fired at the target not to be scored.

The default pause is 3 seconds. Users may however change this setting within the Tape Feed Calibration form.
