Hello?
Still

help

Yes but now filament wont extrude and have no idea why?
I did check the securing screws in the extruder gear as seen here: https://www.dropbox.com/s/1biep3nloz...03847.jpg?dl=0

I also tried controlling the extruder gear on Repetier Host but that was unsuccessful as seen in this video:

and it seems to all be connected correctly. I am unable to push the filament hard enough w the idler pulley is not being pressed.
I checked and set the steps per mm of the extruder to 95 on printer and in software as seen here:

I see the plugs are all plugged in correctly and firmly as seen in this video:
