the thermistor is installed via a diagonal hole in the brass nozzle and has no way of shifting out of place

Please can you explain how this works.

Hi Nophead,

please checkout the attached image,

the thermistor fits in the diagonal hole, the ptfe tube issolates the thermistor wires, now you can just bend the wires upwards, and the thermistor stays in place.

Are you using PTFE only to insulate the thermistor wires or also as a liner inside of the hotend?

Hi,

I suppose the ceramic inner tubing has a quite low roughness ?

If so, you could, I think, ditch the PTFE liner for a Korolon 800 or equivalent coating. it can be applied with a spray gun, has a very low friction coefficient and can withstand >370°C.

No idea about price and availability though, saw a paper about it some times ago. It is quite hard once dry.

Hi alj_rprp,

the trick here is that you don't want PLA to stick to the inside when in a molten or near molten state. for example with PEEK the problem is the PLA will bond with PEEK so you need something that will not stick. maybe Korolon 800 is the answer smiling smiley

the inner part of the ceramic piece has been polished (ID=3.4mm), 0.2mm can be used for coating.

i was also thinking about syperhyperbolic materials like everdry or from neverwet.com

Hello Everyone,

the hotend is available again in 1.75mm and 3.0mm variant
The previous version was sold out quick.

Types:
The 1.75mm version still has ptfe

The 3.0mm variant doesn't have any ptfe.

http://www.2engineers.com/shop/ceramic-hotend-chess-for-1-75mm-fillament/

The 3.0mm variant I will post online later today. Good news about this hotend is someone is already printing polycarbonate(265 C) with it just out off the box. Proofing to me this hotend is ready to handle Higher Temperature ranges

Cheers,
hp

Hi my ceramic hotend and geared steppers arrived today spinning smiley sticking its tongue out

.

Are there any drawings parts to hold the hotend and your geared stepper motor?

I am guessing that this Aluminum Groove Mount Plate for Hot End fits [www.thingiverse.com]. but I can't seem to find the whole set up.

Thanks.

Andrew

Hi hp_ I'm resuming this thread cause I want to know if there are any document available for this hotend. I need dimensions and info about how to use it, how to assemble, if a fan is needed etc.
I'm building a printer and I would like to use your hotend, and I'm planning a 5 extruders carrier also anybody can give a review on this?

Thanks and happy printing to all. smiling smiley
