I bought a E3d v6 24v 3mm hotend and am having an issue with the PLA sticking in the hot end. I start a test print (20mm cube) and the first 2 layers print fine but then the extruded starts clicking and I find that the PLA is in a death grip inside the hot end. The only way I can get it out is to crank up the temp to 240c with the cooling fan off. And the pry it out slowly with players. This has happened twice during testing.
Anyone have an idea what might be causing this. I got the E3d v6 because it is claimed to be the best, but I am having issues with it that I never had with my old non metal jhead.
