Re: E3D v5 All Metal w/Direct Pinch skipping/clicking proble jenschr, I would hesitate to be so dismissive of Sanjay's suggestions - he has a tremendous amount of experience doing hotends, more than anyone else in this thread certainly. Eric's comments are spot on - but the section at the top of the heatbreak is not in the transition zone. I think if you reexamine your findings you will agree - with the aluminum fins cool to the touch, the transition zone happens at the portion of the heatbreak without threads. As for other v5 users having troubles, many of them were nailed down to faulty nozzles (bore length too long) which has been rectified in v6, poor diameter tolerance on the filament, or some other issue. There are about a dozen possible causes - no one common denominator. I would say it is in you best interest to listen to those with the most experience.
