I am just about to convert my Prusa i3 from 3mm to 1.75mm filament.

My setup is a gregs-wade direct extruder, sitting over a genuine E3Dv6. I know how to convert the hot-end, and I know that I have to drill the hole in the extruder so that I can fit the 4mm bowden.

What I need to know is whether to use the bowden clip in the top of the E3Dv6's heatsink - I imagine that it would be simpler to leave it out, but I don't know how that would affect the function.

Any clues/experiences either way would be appreciated.

I have an E3D v6 mated to a BullDog XL extruder and I left the Bowden tube clip in the top of the hot end and it has been working great for over a year. I may be wrong, but I believe the clip keeps the teflon tube inside the hot-end in place and if you remove the clip you'll need to have some other means of preventing the tube from lifting when the extruder retracts filament.

That makes sense... thanks.
