No Extrusion at all

[caddy-cool 0]

Hi guys. Iam having a problem with my ultimaker original, no material is coming out of either of the extruders at all.

 

• Both the extruder wheels are turning and I have seen bite marks on the PLA.
  
• Both the extruders are getting up to temp
  
• The bed is level
  
• Both extruders are level
  

 

Does mean that something is assembled wrong in the hot ends? Do you have tips on what to look for?

Update: I did get a bit of plastic out of extruder one but that is all. It wasn't enough to print it and now there is none again

is there a nice strand of plastic coming out if you turn the extruder wheel by hand before starting a print?

if not: than you have a blockage somewhere. You can try to poke in the nozzle with a thin strand of metal wire (from a metal brush). If that doesn't help the problem could be higher up.
