    What is the advantage? I thought it could go with smaller motors, but I see the suggested motor is still rather large. I guess the only advantage is to have geared push like fro a bowden set up then.

    The advantage is torque.

    With torque comes better speeds and ram purging.

    WOW I did not get any notifications for this thread after they put it back. I'll be answering questions shortly (after I read them all)

    Ok, after reading them, it seems that most of these questions have already been addressed, but if you DO have any more questions, I am now free to answer them!

    Is yours a single or a dual? and how does the dual fit together as it's difficult to see from the pictures I have seen.

    (I'll update this with photos tomorrow)
    Mine is a dual. The direct extruder is mounted around the bracket on the top piece of the carriage. It is almost like a sandwich: the motor mounted on one side of the bracket and the extruder on the other. The bowden extruder is mounted in the same sandwich manner, but is held in place by the back piece of the frame.

    It must be the thin motors that make it so compact, looking forward to seeing photos of the dual, especially showing a view from the back.

    What do you want to see, the back of the printer or the back of the carriage? I have a photo on here already of the back of the printer.

    This is a single extruder or the dual?

    Well its the same carriage for both. The fan shroud is slightly different in a dual, I think this is a single but the way it mounts is the same for both. This doesn't show the motor wire exiting the right side of the motor or the IR mounted, which is to the right side from this view. There's only one hotend mounted in the photo.

    @LiviLammister how much does the 13ncm stepper weights? I bought the 18ncm witch should be 180gram but as you se it was only 149gram. My point is that if the 13ncm really weighs in at 140g the choice between the two should be easy.

    I will try to print the aluminum top and bottom in abs witch will reduce the weight of the 18ncm to about 116-119g (its getting reticules, i know:rolleyes:)

    @Stian Indal Haugseth I know, but the 18ncm Nema 17 from OMC was should be 180g according to spec and it is only 149g.

    On the Bowden setup.....

    If Bowden's - all things being equal - aren't quite as good because of the lag in the length of filament, then wouldn't the optimum place to mount the extruder be directly ABOVE the build plate, like about 20-25cm above the X carriage when it's underneath?

    That way the PTFE could reach everywhere in the build area whilst being as short as possible. Like maybe 1/3 of the usual length.

    So print quality improvements.

    My 18Ncm pancake steppers have just turned up - 150g (very similar to @JesperJuul reported). I just need my titans to turn up now.
