How to print the initial strip

Hi all,

Only had the printer a few days so still getting to grips with it.

The first few prints I downloaded from the web, these had a strip on the side of the model the the printer did first, I assume this is to get the plastic flowing correctly to start the print.

I have mad a simple design in sketchup and when importing this onto xyzware the strip isnt there so the printer goes straight into the main model.

The peroblem is the initial part of the print is not clean and is lifting slightly. How do I add the strip? is this something i need to add myself in sketch up or does xyzware do it somewhere?

Thanks

Dan
