How to configure Cura for upgraded ultimakers

This wiill be a tutorial on how to set up Cura for the Upgraded Ultimaker(s)

Whats going on?

I, Chrankus, just upgraded one of the ultimakers with a new all metal Hotend. This replaces the standard PEEK hotend that is standard on the ultimaker. It was the cause of a lot of headache for many users of the 3D printers. This upgrade should make the printer more robust and will be easier to repair and maintain. Currently only one of the Ultimakers have been upgraded, but we will be upgrading the rest in the near future.

"Great, what do i need to change?"

With this upgrade we are switching from 2.85(3mm) filament to 1.75mm filament. This means that you have to tell cura that you're using a different filament diameter. If you do not change this you will extrude too little filament and your prints will fail.
