Hot End Jamming- Cold Pull Analysis

Hello all,

I had to replace the hot end PTFE tube on my Prusa MINI+. Since then I've been getting clogs.

I've done a few cold pulls that have shown some interesting results which can be seen below and seem to indicate a gap after the PTFE tube (I think)? I tried replacing the tube a few times now, being careful to make sure it fits all the way in per these instructions, but that doesn't seem to fix this issue. About to take the full hot end apart and wanted to make sure it wasn't something obvious. 

Any recommendations on what to do next?

double check the steps 10 and 11.

That big bulge seems due to a lot of space somewhere between the nozzle and the bowden

I'm not an expert. Ma parlo anche italiano 😉
