Looks Interesting: Nozzle X  

Re: Looks Interesting: Nozzle X

I'll install mine tonight and print PETG.

I had trouble getting the heat break tight, but that isn't related to the nozzle. I had to disassemble the hotend a couple of times, whee.

Aside from non-nozzle issues, I've been really happy with the nozzle.

Time to try the Dyze maybe.

Re: Looks Interesting: Nozzle X

It has a lifetime warantee. I would call and activate it.

The warranty does not cover the coatings.

Re: Looks Interesting: Nozzle X

That sucks. I bought one but will not use it with CF then.

With a bit of care, you should only lose the coating at the tip. They specifically mention not using a wire brush for cleaning the body.

What are your temp and max speed settings for this nozzle? I've got a .4mm and am having trouble getting PLA to stop delaminating when printing quickly. Best I've gotten so far was 100mm/s @ 220C.

I'm still experimenting, but delamination can usually be resolved by adding some heat. Slow it down until you start getting quality results, then start adjusting speeds.

I'm using 0.60 and 0.80mm sizes, so my speeds wouldn't help much. I generally don't bother worrying about any speed except external perimeters (20-30mm/s for finish consistency), letting Max volumetric speed settings take care of keeping speeds withing hotend limits.

Re: Looks Interesting: Nozzle X

I think I ordered one too. it just showed up.

yup it is one.. yaa something else to play with.

Re: Looks Interesting: Nozzle X

fyi: here's what a worn E3D nickel plated copper nozzle looks like after 200 grams of glow filament (grid infill where the nozzle bumps into the cross extrusion): if E3D is using the same nickel plate process on the hardened nozzle, well, it won't last long. The Hercules nozzle claims to use a hardened nickel-plate process (E3D doesn't specify plating hardness).

ps: also notice filament is stuck to the "non-stick" nickel plate...

Re: Looks Interesting: Nozzle X

I'm sorry to report that I'm having decidedly mixed results with my 0.80mm Nozzle-X. It's been great with PLA and normal PETG. However, I'm having a hell of a time with KVP rPET (recycled PET). This stuff is very sticky and only prints hot (270C) with this nozzle. Post-print, the ooze is very hard to remove and will cause mesh bed leveling errors if not left. I've experienced the same with some other PETG.

The temps aren't a problem, but I've run into a conundrum when sticky material does manage to get onto the nozzle and cool. With a regular nozzle, I just heat it up, raise Z and brush it off with a soft brass brush. I was hoping to preserve the Nozzle-X coating, so tried a wipe with a paper towel soaked in isopropyl alcohol, but wound up with lint stuck all over the nozzle. I finally had to resort to the soft brass brush.

It's not bad at all, and it seems to repel some materials. The problem is when you run into one it won't repel, cleaning becomes tricky. I'll try a rag, but I think I'm going to wind up just using it as a normal hardened steel nozzle and not count on the coating for much. Using a silicone sock and mastering PEI adhesion has really cut back on my nozzle messes anyhow.

It's probably well worth it if you need the high-temp hardened features, but for normal use, I'm going to stick with the nickel-coated copper E3D nozzles, or P3-D Apollo if I need harder.

i don't think that is a E3D nozzle.

Re: Looks Interesting: Nozzle X

@toaf: Ok - believe what you want. Here's a couple of messages from E3D tech support regarding the NPC V6 nozzle. The top one after I shared that image I posted here. And the second reply was from my initial query asking for the actual nickel-plating hardness numbers.

I'm not against E3D, nor am I disputing I misused the copper nozzle. I'm just unimpressed with copper nozzle: especially the nickel plate which seems is lower hardness than even brass. I finished the roll of glow using a brass nozzle with no obvious wear.

Hi Tim,

Glow in the dark filament is known for its abrasive effects, the better quality the filament the more abrasive it is. Our advice is if you are using any form of abrasive material that you use the hardened steel nozzle. The Plated copper nozzles are not designed for use with abrasive materials they are designed for high-temperature printing in cases where the silicone sock cannot be used.

I have had a word with one of our engineers and shared the picture of the nozzle wear, he said he was not surprised to see that wear from glow in the dark filament, he was impressed by the evenness of the wear and commented that you must have a good machine.

If you have any

Kind regards,

Hi Tim,

Thank you for your email.

Unfortunately, I am unable to share the exact hardness ratings for our materials. The nickel plated copper nozzles are not designed for use with abrasive materials the plating allows for a non-stick surface for the nozzle at higher temperatures where the silicone socks cannot be used (or when they are their lifespan is very short) The hardened steel nozzle is a A2 tool steel with a chemical coating If you are worried about the abrasive nature of the filament being used always use the Hardened steel nozzle. The Plated copper nozzle is not intended for use with any abrasive/ filled filament.

If you have any more questions feel free to ask.

Kind regards,

Daniel

Re: Looks Interesting: Nozzle X

@bob: I think I've found or rediscovered a trick for getting PET off the nozzle. I essentially let a wad of PET build up, turn off the heat, let it cool, then do a cold pull from the bottom. It seems to work well.

I was talking about the nozzle listed in tim.m30's post.... ahh never mind I soo missed a line in his post..... my bad.

Ah, that's an interesting idea. There's usually enough to grab as it warms. Hmm. I wonder if dabbing with cleaning filament, or letting some melt on top of the PETG then cool would provide enough grip for a "reverse cold pull"? I'll give it a try when I re-load that nasty filament again.

Does it come off cleanly with the Nozzle-X? That coating might be helpful after all.

I've found that with every filament I've tried on it (PLA, PETG, PC, Nylon) that pulling off the crap stuck to the nozzle works incredibly well when the nozzle is cold.

Re: Looks Interesting: Nozzle X

Still liking this nozzle, has worked well on PLA, PETG, TPU, Nylon/CF. Few blobs and as Adrian said it is easy to remove any crap. Also not noticed any issues with wear. The only thing I had to do is up my print temps from when using Brass. I would not go back.

Re: Looks Interesting: Nozzle X

I'd always used a soft brass brush to clean the nozzle and heater block, and was dismayed to read this would remove the coating which is not covered by warranty. After poking at it with paper towels and toothpicks, I realized a strip of cardboard works quite well on a hot nozzle. Optionally dunk one end in alcohol, then clean the hot nozzle. The fraying cardboard provides a good brushing action without the lint of paper towels, and is more thorough than toothpicks. Trim it down when it clogs too much. A small thing, but this makes using Nozzle-X (and any coated nozzle) even less annoying. I give them a good clean on removal prior to storage.

Re: Looks Interesting: Nozzle X

Cleaning with a brass brush removes the coating? Darn, I bought this thing as it was promoted to be virtually indestructible... There goes my trust in another company 🤐

They're pretty clear on the web site that the warranty covers abrasion. The main nozzle page states:

Comes with a limited wear warranty (covering wear only).

The linked warranty page says:

The warranty applies to wear only, this means the nozzle is not guaranteed to never block or jam. The no-wear refers to the geometry of the nozzle, and does not apply to the non-stick coating. It is expected that the non-stick coating will wear both internally and externally when used with abrasive materials. We are only providing a guarantee of the wear to the geometry of the nozzle to the point that it would significantly affect functionality.

I can understand being bummed if you missed it, but I don't see any reason to lose trust in them over missing the info. Now that I've started using a strip of cardboard, I'm finding it works very well.
