Vtube-laser logo.jpg How to perform quick scissor motion end-scans.

Why the End-Scan technique is important

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.

How To Use This End-Scan Technique

  • 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.

Approve the Measurement On the Screen

  • 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.

Using End Target Adapters



  • 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.
