    Hello folks
    I have feeding problem on E3Dv6 usage.

    Problem) feeding filament may stopped during print

    My Confirmation
    1) failure does not show when manual feeding via console.
    2) head and plate Z-gaps are measured as 0.12mm at both X-end.
    3) PLA and ABS shows both failure.

    My mods
    0) this Robo3d has started from Kickstarter version.
    1) Y-axis upgrade using with glass plate from Robo3D.
    2) Y-axis NEMA motor gear has been reinstalled with screw. (No screw had been settled)
    3) E3DV6 1.75unit has been installed with PTFE tube internal 2.0 mm.
    4) Hobbed bolt has been exchanged for reprap (tentatively)

    Failures Picture
    It shows jamming in hot-side.
    Removing filament shows as picture (PLA). 20150419_115003[1].jpg 20150419_114949[1].jpg 20150419_115003[1].jpg 20150419_114949[1].jpg

    Fan's running? Feeds normally by hand?

    How much tension is on the hobbed bolt? Is it grinding filament

    Marlin software has been updated also for E3DV6.

    Hello Mike
    How to measure on this hobbed bolt tension ?
    My feeling on this tension looks tighten from before.
    Should I makes loose on it ?

    regards

    My impression on current setting shows delayed feeding after high speed feeding by manual console.

    If you tell it to spin faster than it's capable or extruding then it will grind down filament.

    Try slowing your print speeds down and don't do manual controls.

    After clean up of E3D parts and nozzle/PTFE TUBE exchanges.
    It looks feeding goes well now.

    I will look into current setup .

    That picture looks like heat creep. Make certain the fan on the E3D itself is running (full speed).

    You don't have it assembled correctly. You have the heater block screwed directly up against the heatsink. This is not allowing the heatbreak to do its job, which is causing your problem. The fan can't keep up. Review the assembly instructions again. When assembled properly, it should look like the assembled pictures Mike has posted in his review thread.
    Also, where did you buy it from? I ask because I'm not sure it is possible to assemble an authentic E3D incorrectly like that (although I could be wrong). There are a lot of counterfeit E3D V6 on the market from China. One of the worst problems with these is that the heat break is just a straight constant diameter threaded rod instead of having a stepped diameter.
    Here is the list of official authentic resellers: e3d-online.com/Genuine-Check

    Then you need to check your assembly. If the heat break is not installed correctly you will get the creep.
    The heater block and the heat sink should be separated. They do not touch. There is a gap. On my v5 it is about a 1/4 inch, but I think I remember the v6 might be a little closer.

    Ok, I got your point. It should have gap between heat sink and heater block.
    I shall fix it again on next time.

    I do not understand parts "COLLET?" for PTFE universal version of E3Dv6.
    Some picture shows as some black parts between heat sink and PTFE tube.
    Is it parts ? or "Tape" that you have explained on this query ?

    regards

    Here is a picture of mine (might be a little hard to see). It is not the same since mine is a V5 with a volcano kit on it and the gap is small (1/8 inch or so). However, it is there.

    It is also a bit dirty ;) It is a busy hotend.

    The E3D v6 has a plastic (PTFE) tube that runs from the extruder down into the cold section of the hotend. He is just trying to confirm that you did install that correctly.
