One of the main challenges of using a traditional chuck rotary is the time it takes to set up and swap cups.

Most 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. 

Enter the PiBurn Grip.
In this 60-second video Robin demonstrates how to swap cups of different shapes and sizes. She does four of them at about 10 seconds each 

Thank you Robin for the excellent demo!
