Explain Coasting and when to use it?

[LePaul 287]

I noticed the beta has the ability to coast and I don't quite understand how that works.

Could someone explain that beyond the brief description in Cura (beta)? I'm really intrigued to know when you would want OR not want to use that option (Pros and Cons)

Thanks!

A great simple explanation on the colorfab ngen page

 

Coasting is a nice option included in Simplify. This is the act of stopping the extrusion just before a travel move is triggered, this helps get rid of the pressure in the hot-end and therefor also making a retraction move more effective.
