E3D has released new hotends!

[elmoret]

Not exactly sure of the filament path inside the heater block,.

It's pretty clear from the images on the website, it's cross drilled and tapped, presumably for the same screw caps they use on the water cooled block of the kraken.
The 2 inputs and the output then are drilled at 90 degrees into that orifice.
The filament should be molten in that section, so it shouldn't matter, the additional volume really just becomes something additional to purge. a direct path isn't needed through the heater block, printing is more about pressure when you get into the molten filament bit.
I'd like to have seen a physically smaller heater block with more closely positioned inputs on the cyclops, but that would have mean't an entirely different heatsink design for the cyclops vs the chimera, which would have meant additional tooling/cost.

It's interesting.

It's plugged with pressfit ball bearings, not screws.

I also contacted Josh at E3D and asked him what the volcano is.

Volcano is something E3D plans to release details on in the next week or two. I've seen it.

Aw, Elmoret, inquiring minds want to know.
It is not fair to talk about it but only throw out the word.
Bad Elmoret! Bad Josh! Bad Sanjay! (We really love ya all!)
You've seen it they have seen it but we need to see it!!!
I've got it, we will boycott all Hotend Distributors!
Wait! We can't do that then we can't buy hotends!
It must be a conspiracy!
We are a bunch on impatient Delta Printer Users and need to know!!!!

Maybe volcano is the feature of your thermistor coming loose. Haha. Volcano of plastic, smoke and fire.

Somehow I don't think that is it but a very good guess!

Hi Everyone,

Josh here from E3D, I've not posted here before, but been a lurker for a while..

Volcano compatibility was actually not supposed to be listed on that table (oops!).. But now everyone has noticed it seems a bit pointless to take it down.

I can't tell you what Volcano is because it's not due for release for another couple of weeks. With that said, if anyone can guess what it is then we'll give them a free one when it does come out.

Edit:
Also, if anyone want's to ask anything about the two new HotEnds, fire away!

[JFettig]

Can you post mounting dims? I have a mount designed based on assumed dimensions but I would like to finish up design before I get mine. Also, are there thermistor holes on both sides of the heater blocks?

[joshuarowley42]

I have just been sorting out the assembly drawings today. These are not quite finished from an ISO8888 standpoint, but it should give you all the information needed to start designing mounts etc.. I will be doing the remaining component drawings and uploading them over the coming week.

Chimera Assembly Drawing
Cyclops Assembly Drawing


As you can see in the Chimera assembly drawing, we recommend having the heater blocks swivelled around 180* from each other. This means that the holes for the thermistors are facing out on the two blocks.

The heater cartridges are ~20mm long so would have needed more separation between the two channels to be arranged in-line. We wanted wanted to keep the width of the Cyclops to an absolute minimum to reduce transition times and the volume of molten filament so there was a bit of a trade off to be had. Compatibility between the Cyclops and Chimera is very important to us - dual extrusion is not a one-size-fits-all affair..

I would guess extruder,,,, and to be more descriptive, one that mounts to the compatible hotends to enable printing with the more flexible filaments.

[Nylocke]

Its not going to be an extruder most likely. Given the name and the compatibility, if it were an extruder it would be compatible with everything, but the cyclops isn't compatible. E3d always names things "descriptively". Chimera is a multi headed best that breathes fire. Cyclops has 1 eye while most things have 2. Kraken is a giant octopus. If they are calling it a volcano, I would think it has something to do with high temperatures. Maybe a heater design? That could explain why the cyclops doesnt support it. Or maybe a new temp sensor, and because of lack of testing/the design, the cyclops isn't compatible with higher temps?

[BenTheRighteous]

My guess is that it's a heated nozzle. I notice that the "Volcano compatibility" and "V6 nozzles" compatibility" tables are identical.

Perhaps E3D is looking to maximize their temperature range, and they find they are shedding too much heat through the heater block? So, they're trying to localize heat generation as much as possible. Perhaps with a volcano nozzle you won't need a heater cartridge, and perhaps the thermistor (or thermocouple?!) is integrated into the nozzle as well!

Maybe that's utter craziness, or maybe it's plausible - I don't know, but that's my guess.

[Chrissi]

When you think about it, nichrome wire wound round a ceramic spool with an internal thread that can accept nozzles and an embedded thermistor would give a fast responding compact hot section.

[0110-m-p]

Thanks for the drawings, I'll get started on a Rostock Max mount design and share it when I'm finished. Just placed my order for the Legend pack through Filastruder this morning.

As far as Volcano goes, I think it is a fully insulated heater block that will hold the heat in better and keep more consistent/hotter temperatures. It will be a replacement for the current heater block design using V6 nozzles. It is incompatible with the Cyclops because it uses a large heater block that is different than the V6, Kraken, and Chimera.

[Generic Default]

The volcano is a new type of heater block nozzle combination that can go far over the 300C limit we're used to. It's a fact.

I'm actually just making stuff up. But it probably does have something to do with thermocouples.

[bubbasnow]

Does a ship date exist for these yet?

I just have a question. Why are all these "open source" projects released with a "no commercial uses" exclusion? That isn't really open source, then...

American lawyers.

[redoverred]

American lawyers.

No, it's because they want to have open source so people can use their designs mostly freely but still cannot sell their designs themselves. Your comment is bad and you should feel bad.

[bot]

That's not open source then. The point of open source is that commercial entities can build off each other's progress. Without commercial entities being allowed to, there is basically no point in being open source.

Just like when SeeMeCNC runs a contest, the model can't be "no commercial uses."

It's not open source with that limitation. It's fine if you want to be proprietary, but admit it when you are...

[redoverred]

there is basically no point in being open source.

I'd rather have the ability to see the plans for something and recreate it or modify it for my own uses than not, so there is a point. It's either allow for companies to limit commercial use of their product's "open sources" or don't get any source at all. I'm not arguing with you about this anymore, because you're obviously a rabid open source fanatic. Please stop shitting up EVERY conversation on this forum with your fanatical beliefs.

I guess that is a hotend with three nozzles.

[mkx]

Ive seen it referred to as an Upsilon, and thats how it works. If your hotend design is good and you have a good extruder design they work quite nice from what I can tell. I'm a bit skeptical of the cyclops design as well. Not exactly sure of the filament path inside the heater block, but from what I can tell it probably won't be the best for retractions, if you can even retract at all. I think the color mixing aspect would be pretty cool, it wouldn't probably be a full blend, but it would probably result in a sort of wavy mix of the two colors. I'm waiting for E3d to release CAD drawings of the Cyclops heater block, really wanting to know what they've done.

What is this sorcery you speak of? I haven't been able to find any more info on it.

No, it's obviously made of plutonium so you don't need any electricity to heat it.

Rpress experimented with one, and Generic Default made one for the V5 where two PTC connectors go into one hotend. http://forum.seemecnc.com/viewtopic.php?f=54&t=2597

That one only works for Mag arms, unless of course you want to modify it

Get bent.

It is VERY important for this entire industry that people learn the true meaning of open source. This includes allowing commercial entities to work with ideas. Give me a break. You're basically saying the only people allowed to improve upon designs are those not being paid. Why don't we allow for people to get paid while helping an entire community?

I can say whatever I want, whenever I want. Don't tell me what I can say or not in any conversation.

I'd like to remind you that you wouldn't have a Rostock Max if Johann decided to add a non-commercialization clause to the licence he used when he developed the Rostock design. Of course, he didn't. It was a GPL license, I believe.
