How to perform quick scissor motion end-scans.

• Back to VTube-LASER

This end-scan method is useful for ease-of-use and quickness.

Please keep in mind that our tests show that it is the least precise of the techniques that we recommend.

We also recommend the End-Scan Using the End Wall technique and the most precise End-Scan Using End Targets.

• Align the scanner with a slight scissor angle across the end as is shown in the image on the right
  
  
• Press the green button until VTube-LASER is finished scanning all the end stripes.

When it is time to perform and end-scan, use the following technique to scan the target:

• Aim the laser at the target so that it strikes the target as perpendicular to the surface as possible. Avoid returning any points other than the target.
  
  
• Hold the laser still when collecting the stripes across the target.
• Consistently place the line across the same area of the target from measure to measure.

• The resulting geometry on the screen should appear like the image at he right.
  
  
• The end point generated on the screen should perfectly coincide with the stripes.
  
  

• If you prefer using more durable end target adapter that plugs into the end of the tube, then they can be manufactured for repeatable measurements.
  
  
• The end target surface should be painted or covered with a flat white or near-white target.
  
  
• The offset from the target to the tube end is entered as a negative value in the Part Setup menu for either end.
