My machine has been on for 346:35, printing for 281:20 and gone through 176m of material.
It's tough to get a good photo with the white filament - the impression is actually a bit stronger than this picture indicates. The feeder drive seems to have a pretty good grip on the material but even so I do hear it slipping with a bit of frequency during printing. The tension on my feeder drive is pretty close to the maximum but there is a little a little room to tighten it a bit more.
Is there a good photo tutorial on breaking down the printer head to check the PTFE coupler? Would be great to know what I'm doing before I start monkeying around with it. Thanks for you reply labern.

Have you checked to see if the filament is slipping? Is there much impression from the feeder drive wheel on the filament?
How many print hours have you done? as the PTFE coupler could be deformed.
