Ok, so whats wrong?

That's not bad for a first attempt!

My only experience with hot ends is the RepRapPro mendel one which has been good (no jams) but that's a bowden cable type (you're better with direct drive if possible).

Seems a shame to give in when so close but the Ormerod does look like a nice machine.

Thanks, I did just get it going again, release pressure, force material by hand very hard and flush through, tighten feed pressure and start print, again the first layers failed, then worked ok then it failed near the end.

Again, blocked solid.

This time i fitted a large thin washer between the hot and cold ends to dissipate heat from the stud tube, all that gets hot now is the last 5mm of tube before it enters the hot end and it still jams.

The only thing i haven't got is a PTFE liner, maybe that's all that's needed??

Just guessing of course.

It is annoying, but there again it is eBay junk once more, but I really dont want to start throwing more cash at this if the Ormerod is any good.
