Extrusion Problems with E3D Titan Aero CR-10S Upgrade

[tophster]

Hello,

I have just upgraded my CR-10S with a Titan Aero using E3D's Slimline stepper motor. After getting it all set up, adjusted so it was extruding well when using the extrude command I went to do a test print. I get this strange stringing pattern on my first layer. I attached a picture for you to see what I mean. What is this from? Under-extrusion? Any advice would be appreciated.
