Has anyone got the new august 2012 extruder working ? Iv managed to get it assembled based of the photo on the sumpod website, but can't figure out where it goes? I have a gap in the back but no way of mounting it and I wonder if I'm missing a part.
Also has anyone assembled the newer hot end? Its an all metal one, and totally different to the one on the site! It has a fan mounting plate that I don't know how works, does anyone have a picture of this newer hot end?

I would try to mount the fanmount vertical. The fan schould blow at the hotendheatsink.
Can you show me a pic of the backside of your sumpod? I there a hole for the extruderstepper?

Thanks for the reply, i have a hole for the extruder in the back, but i think im missing a mounting plate for it?
As for the fan mount ill try and just drill some holes manually for it.
How about that hot end? iv literally built it blind. Does that thinner PTFE tubing need to do down the length of it? i seem to have alot of it left over!
Thanks for all your help!

No, the small PTFE-hose ist just left.
For the extruder stepper you need some sort of mountingplate.
If there is none in your delivery, than a piece of thicker sheet metal should work.

Thanks for the reply, iv piped the PTFE-hose right down to the end of the nozzle, hope that is right!
Way ahead of you, making a mounting plate out of some think acrylic, hopefully it will do the job!

If the long PTFE-bowdentube fits down the hotend, the it is correct.
In the older hotendversions its the same.
Acrylic should work. It just has to be rigid enough when the stepper is getting warm.

Brill okay, i just thought the transfer between the thicker tube and thinner wouldn't work quite right inside the hot end? ill test it out and see what happens.
It should be okay, its a good 5mm thick, ill see how it performs, i have some metal plating i could use instead if its an issue.

Which PTFE-hose did you pushed down in the hotend?
The big one with 4mm outer diameter an 2mm inner bore or the thin?
The thin hose is only for insulating the resistor an thermistorleads.

The thinner one, as its the only one that would fit, the thicker one wont go much past the top connector?
Apologies for my stupidity, but i can find NO info on this hotend!

Can you messure the id of the hotend?
It seems to be relative new, so there is no documentation on the web.
If there should be an PTFE-hose going down the hotend, than the big one would be it.
But at the moment there are some all-metal hotends upcoming, that need no ptfe. So it would be good to figure out if there is a need of ptfe.

How do i measure the id?
the only other place i could imagine it goes is in the coupler, as iv seen that in a few other all metal hot ends.
Thanks For the help

Unscrew the pushfit from the hotend. Take the hotend out of the mounting block and try to measure the id of the hotendpipe. Just below the threads, where you screw in the pushfit.
Calipers should work.

It seems to taper to a thinner diameter, is it the thinner one thats needed? as thats the same outer diam of the smaller PTFE hose.
