E3D v6 ?

1) The v6 has subtle changes, but none that would confuse anyone going by the wiki. Essentially the same, shorter, and thermistor placement and method securing have been changed for better readings and easier upkeep.
2) Since the v6 is so new, I doubt anyone has one just lying around that would be willing to part with one. However, I have a v5 collecting dust, never used.
3)Mechanically speaking, it is very simple. The v5 can be irritating wrapping the kapton, but nothing a little patience and calm steady breathing at worst. v6 seems to be a little more straight forward, faster to assemble, bit easier.
   Firmware side of things will depend on your working knowledge and skill level. If you are like me (less than zero on a 1-10 scale), it may give you some issues. But the firmware update process really depends on which board you have.

Don't be worried! It isn't nearly as bad as you may think. Just be certain you have read the wiki many times, and even walk through it as you are assembling for the first time.

I think Azerate would be willing to print those parts - I would but my printer is running Filastruder hoppers.

Let me know if you have E3D questions!

Thank you guys you saved me.

On a side note, I just thought of something.  In the e3d v6 videos it says they have a .25 mm nozzle.   If you have a good cooling fan .......   how small do you think you could print?   Lego gun small you think?     (  if you cant tell I really need to print small... lol)

You will want a direct feed. And you are correct that SD is a direct.
Bowden moves the motor to another location then feeds it through a tube into the hotend. That would also require a different setup for your extruder and possibly carriages. Though it is possible and has been done.

Talk to LdyMox on smaller than small prints. She's had some good results with her tinkerings. But the key to any good result will always be calibration, calibration, calibration
