Extruder head assembly...does screw go all the way in?

[LePaul 331]

Mine doesn't go all the way in...should it?

If I may suggest an edit to the Wiki...

Route the CPU fan wires first, once the other wires are in there, good luck getting that plug connector to fit thru!

Follow up questions...

Does it matter which direction the aluminum block points?

From all the moving around, twisting around building it, that's sort of where the aluminum block has wound up. Do I need to twist is around to be positioned elsewhere?

I got my screw to go all the way in but it doesnt need to I think. As for the aluminum block, it does not matter because the top threads are alligned w/ the bottom ones.

Ok, so it wont other anything being oriented the way it is? I wasn't sure if cooling shroud would be cooked being so close to the thrmo-wire stuff

I had mine crooked the other way and it melted the fan shroud (easily fixed with some kapton tape). But to answer your question: Twisted isn't an issue. It doesn't matter much - at least not with single extruder. Not sure about dual extrusion.

I don't think the heater cord will get hot enough to melt the shroud but it might. Order some kapton tape on ebay just in case you need it. It can withstand amazingly high temperatures and is easy to work with (it's just tape). And it is non conductive.

Most of the time with a single extruder, the wires exit the hot end form the rear and have no clearance issues with the fan shroud

The orientation of the aluminium block doesn't matter for single extruder... However, for duel extrusion you will have a hard time getting both extruder to fit unless they're oriented the same as the pictures.

As for the set screw... It should go in all the way, but as long as it's pretty tight and holding everything in place then I don't see it being a problem if it's not quite in the whole way.

Cheers,

Troy.

Like a couple of people have stated, it should go in all the way.

But i know some people who use the head of this screw to 'lock down' the cartridge heater.

The point is; a tight fit is a good fit.

The orientation of the heater block is fine for single extrusion, but for dual extrusion you would need to change it.

If you would like to add dual fans you need to change it too.

I don't think you should worry about the cartridge heater melting away your fanduct.

Hi Sander,

The Wiki didn't mention how far the screw should go in, mine got really tight half way in but I was able to get it almost all the way in.

Thanks for the info on the extruder alignment. Eventually a second one will go in as I bought that option. But for now, as you advised, I will stick with one, get some experience with the Ultimaker and upgrade to that later.
