Swapping cups on a laser rotary chuck attachment is frustrating and painfully slow.
One of the main challenges of using a traditional chuck rotary is the time it takes to set up and swap cups.

Most laser rotary chuck systems require a tool
to tighten and loosen the jaws and they do not have a natural stop to make sure the cups sit evenly in the chuck each time.

This takes a lot of time and tinkering to set up perfectly and then take it off again. ![⏳](https://static.xx.fbcdn.net/images/emoji.php/v9/t38/2/16/23f3.png)

Enter the PiBurn Grip Laser Rotary Attachment from LensDigital.
In this 60-second video Robin – a PiBurn Innovator, demonstrates how to swap cups of different shapes and sizes. She does four of them at about 10 seconds each ![](https://static.xx.fbcdn.net/images/emoji.php/v9/ta4/2/16/1f92f.png)
