I'm rather frustrated and if I can get away with being blunt I'll start with - this is the worst extruder I've ever used, and the Anet A8 extruder was faulty - the cheap $15 chinese replacement was far superior. So maybe mine is also faulty. I purchased mine from Makershop.co.nz as NZ shipping takes a long time from overseas, being so far away. We live in a first world country with businesses as honest as you could hope for (certainly more honest than the US) and no one willing to risk infringements - so maybe it's counterfeit, but it doesn't look it, and it has that shiny genuine logo too. I have consumed all the reading material I can find on installing the Titan and would like to believe I'm reasonably informed, so maybe I missed something or maybe the documentation did, I don't know. The issue: Filament stops being fed through part way through a print, prior to that it works beautifully. Eventually it seems the lack of proper grip causes it to stop going through and it chomps the filament. The origin of the issue stems from the big gear sitting too close to the motor/extruder mount and the bearing (and thus the feeding hole) being too far out from the motor mount - However I see no way to space this. The large gear is sitting perfectly flush with the pinion gear as per the instructions. If I want to make them flush, I have to then conclude that all assembly instructions are wrong and put the pinion gear too far forward. Since my mount is 3mm thickness, as per the wiki (still has tons of info the docs don't) I tried printing a 4mm spacer (jammed on the last layer, but works perfectly regardless) and used the longer provided screws. I will try to get a picture tomorrow as I can't produce sufficient light (sorry).
