Printer Built, Whats Next? (Calibrations)

My first initial guess is that your nozzle diameter/filament diameter is set incorrectly in your slicing software. This would lead to incorrect extrusion rates when trying to print a sliced part, but would not effect pronterface extrusion.

Where can i change these settings?

In Slic3r you would turn on Expert settings by doing File/Preferences/Mode=Expert
And then on the Filament_Settings tab adjust the Filament Diameter to the right number.
And then on the Printer_Settings tab adjust Extruder_1's Nozzle diameter to the right number.

Ive ordered a new extruder nozzle as the nozzle was blocked as well as having a defect on the tip meaning the plastic curled during print, will update when new nozzle is fitted
