Laser Displacement Golf Ball Scanner
![](https://openbuilds.com/data/article_cat_images/s/0/298.jpg?t=0)
Getting an accurate scan of a golf ball can be difficult with general-purpose 3D scanners. This purpose-built golf ball scanner uses a very accurate Keyence LK-081 laser displacement sensor with an Open Builds linear actuator for the vertical axis and a Sherline CNC rotary table for the turntable. Scan detail is determined by the sample step size and can be set arbitrarily based on desired scan time.

Reference sensor for CNC Tools
![](https://openbuilds.com/data/article_cat_images/s/0/286.jpg?t=1389472260)
For the x and y Axis you set the zero point with a limit switch, but how can you get the zero position for the z Axis? You have different thickness of material to mill and when you change the tool, you have also a other z Axis positon. With the Sensor, you can define the zero position of the piece automaticly.
