HT Hotend nozzles?
Does this new HT hotend use the standard nozzles? I was confused by the announcement talking about easily swapping the hotend in about a minute. It sounded like a person would be doing that often. If it uses the normal nozzles I already have, wouldn't I just put in this new hotend and then use it all the time, even for lower temperatures? That's what I'd have thought, but now I wonder.
RE: HT Hotend nozzles?
I actually have the CoreOne, not the L version, but I put this post in the L forum. oops. Shouldn't matter for my question, though.
RE: HT Hotend nozzles?
I guess you can use whatever Nextruder nozzle you would like, but they have a max temperature rating of 300C, so you don't get the benefit from the ObXidian 500 nozzles which can achieve 500C. Obviously the hotend itself has a heating / sensing capability of 400, so that's the number.
Also there is no silicone sock for these temps, but I might be wrong.
There is little information on it right now, but the price on the webshop should include the new heater cartridge, temperature sensor, heater block and an E3D ObXidian 500 nozzle and of course the firmware update to be able to use it. We will see.
RE: HT Hotend nozzles?
It sure looked like it was using the standard nozzle configuration. I just ordered, along with other stuff, the $90 High Flow 0.4 Ob...500 nozzle, so maybe I got carried away there. But maybe the included one won't be high flow and I won't feel so mistaken 😀 Also, I just ordered the Core One L, so it ends up I posted to the right forum after all.... I really like the aluminum heat plate and active heating ideas, and of course bigger size is nice. Thinking ahead to the upcoming multi-tool add-ons, I suppose those won't go to the really high temperatures, so that's a consideration for skipping that add-on. I have a 2T XL so I can still do logos, simple graphics, scales, two materials..., just not the colorful toy and artsy stuff, but I'm not into that anyway.
RE: HT Hotend nozzles?
Yeah, the precise configuration is unknown, we will see when the hotend comes out.
I don't see too much benefit of a high flow version though in this case. If you look at the filament types requiring these higher temps are mostly abrasive types and very rarely high-flow. Most of the carbon fibre and glass infused PPA, PPS, PA filaments requiring slower printing speeds, with standard flow characteristics, mostly a straight 0.6 nozzle to avoid clogs and be able to cold pull if there is any. If I would have to choose one, I would definitely go for the standard flow 0.6mm. Also standard flow would not be oozing like a high flow one.
But for a general 0.4 nozzle for every temp and occasion is a great choice.
RE: HT Hotend nozzles?
I would most definitely not use HF nozzles with high temp engineering materials. Also, most of these materials are abrasive due to CF and GF additives. Due to the lower volumetric flow (print speeds) there is zero advantage to use a high flow nozzle. I use Diamondback nozzles for these materials.
RE: HT Hotend nozzles?
Thanks for the inputs. I probably got ahead of myself with the fancy nozzle. We’ll see how it goes with whichever filaments I decide to try. I have a standard flow 0.6 ObX already so that might end up being the best, except for the really high temp ones.
RE: HT Hotend nozzles?
Beside my 0.4 and 0.6 HF ObXidians what I only use for fast printing PLA/PETG, I mostly use a 0.4mm and a 0.6mm Diamondback for almost everything. I hope there will be a 400C+ Diamondback soon, I would rather go with that one if that will be a possibility.
RE: HT Hotend nozzles?
My current "problem" is I have an INDX system on the way soon and will have a spare Nextruder and $500 worth of (what will then be) useless nozzles.
RE: HT Hotend nozzles?
What are the chances the INDX system will accommodate the high temperatures and engineering filaments? I think I'm going to be happy for a while with the Core One L set up with a 500 nozzle for "all material" printing, and my 2T XL for two colors (enough for me with functional parts instead of more decorative). Everybody has different use cases, so there's not a single setup good for everyone. If I have trouble with the High Flow 500 nozzle I can use the straight 0.6 ObX, but I expect I can just avoid the 'cloggy' filaments probably. We'll see. I'll learn.
RE: HT Hotend nozzles?
Everything is a compromise. For INDX, the high-temp printing was not the main focus so I guess the temps will be between 300C and 350 at most. Most likely at the 320C mark. Also there is very limited visibility to the print area.
On the other hand the nextruder setup is well rounded with lot of nozzle options, and with an MMU setup for occasional material switching, can be a good alternative. But the chamber temps even with the core L are a tad low for the high temp filaments.
I also preordered the INDX, but I'm not sure I will buy it at the end.

320C is still 30 degrees hotter than the current Nextruder. This opens up PPS and allows for better layer adhesion with PA and PPA material types.
