Solved Filament not feeding in robo3d

Ok great! Thank you so much! I'll let you know how it all works out!

 

Well, I torched it and got all the PLA out, or so I think. I stuck a long paper clip through it a few times until they came out clean. But I still can't get any filament to feed back into the extruder - it will go about 1.5" in from the idler and that's it. I've never had good luck feeding filament into this printer - the two we have at work seem like a piece of cake compared to this - I struggle with it :-/

 

Yes, I have the extruder fully out, I heat it up and can't even feed filament through that way - it goes in about 0.5in. and stops. But I can stick a paper clip in about 2.5in........makes no sense to me!

 

I know I shouldn't have to remove the extruder completely, but I wanted to see if I could even feed filament through it, and I cannot. Can you show me how I remove the nozzle from the hex part?

 

I've tried that, the hex part just keeps spinning around, the screw does not loosen up.

 

There's a set screw on the bottom of the hex heatsink. You need to tighten that up to prevent it from spinning.

For removing the nozzle, there should be a 4.5mm spanner in your tool kit. Grip the top part of the heat break and a 7mm wrench to grab the nozzle to remove it. Best to do it while hot so be careful not to burn yourself

Be sure you dropped the nozzle out of the holder and verified there is not any filament sticking out

 

Mark T sent me a video and I've got it all apart now I just don't want to break anything on my printer, so before I take anything apart I want to know exactly how to do it - but I only have to do it once. Thank you all so much for your help!!
