Extruder Motor Not Working

[serifos 0]

Hello,

I just finished assembling my new Ultimaker, but I have a problem with the extruder motor- it is only moving back and forth in small steps? After I have heated the extruder, I have tried to extrude something using Cura but when you send the command the motor just moves back and forth? Any ideas on how I can resolve this? Is it possible that there is a problem with my board?

Thanks.

just asking, is the little small white plastic wheel from the extruder motor very tight againt the large extruder wood wheel ?

if you have positioned the extruder motor to close back against the wood wheel, that maybe could cause problems`?
