In Step 1 - HE280 Assembly http://seemecnc.dozuki.com/Guide/Step+1 ... ssembly/45
I've found the heat sink and the heat break and I found a black plastic tube that is about 4.3mm (diameter) I'm assuming it is the 4mm PTFE? But I don't see it in the diagram to confirm, and I don't see what I'm testing the fit too? It doesn't seem to fit IN the heat break (Larger end), without cramming it and the fit is just off enough that I want to make sure I'm getting it right.Step 12 — Preparing the Heat Sink / Break
Locate the HE280 Heat Break and test fit the 4mm PTFE tubing. The tube should insert and fully seat.
Am I looking at the right part? Either way I need a bit of guidance as to what I'm looking to "test fit" and what I'm looking for to "pass" that test. does it need to seat all the way down, just fit in the whole a bit?
Thanks in advance!
