Just installed my E3D v6/Titan upgrade kit following the video tutorial and online instructions. I loaded the firmware using the correct Cura version (I use Simplify 3D for my prints). I am having an issue with the new Titan extruder motor making a loud shrill noise when trying to either load or unload filament and then shutting down. It never actually loads unless I push it all the way to the nozzle by hand and then it never oozes out when it is supposed too. I did verify that the hot head is getting hot. Also when removing the filament it will make the shrill noise and then only move a few mm, pause, move a few mm, pause, and on and on till I actually remove it. I have checked and rechecked my connections and found nothing. Any thoughts?
