Hexagon Hot End?

I will do some review pictures of the E3D, similar he did. He seems to use such kind of microscope:

Can you confirm that the E3D is produced in UK, in case not all parts are made in UK, could you please let me know which, so i don't write wrong information in my upcoming review.

Can you give me one example of any of our products which we "copied" , so called counterfeits?
This is a link with some products we developed, which of those are "counterfeits" ...?

Test mounted the Hexagon and heated it to 275c before I tightened the nozzle/heated block to the heat-break.

Then I added the rubber isolator, and tested temperatures gradually up to 270c - the rubber seems fine, no smoke or melting.

Next step is to mount it on my OrdBot and start test different filament types.

 

Sorry, I'm a bit late to this thread. Earlier 1d1 was telling about issues printing Taulman that gets clogger after few hours due to its diameter being 1.95 or more instead of 1.75. Looks like I'm having the same exact problem with my E3D. Is it normal for Taulman to be that thick? Tried Bridge and T-Glase...

@printed solid
don't worry, i will only post pictures from exact metal parts he posted. I have nothing to say bad about E3D because it's a great product from great people. CAMBO's point of posting those pics is to show under microscope the machining artwork of "chinese products"

@denys dmytriyenko
hexagon, e3d, and most hot ends will clogg if you are using out of specs filament or filament. I made few pcs hexagons for "out of specs" filament, i am not sure it could work, but if you want to give it a try, please PM me your address and i will send you one. I cannot guarantee it's working, it's just a test, okay

 

hexagon prototype 25mm cooling fan mount. had to make something since hexagon doesn't come with a fan shroud or mount..feel free to criticize the design... it's just something I put together at the last minute..

 

It looks great to me. Excuse me for a stupid question but will it fit into the stock robo3d extruder?

Regards, Daniel

 

Yes it'll fit in the stock holder just fine.

I think it is advisable to increase the bore diameter to 2mm. At the small ID you're really limited on filament. Also Bowden tubes generally have a 2mm ID and it's ideal to keep a consistent ID all the way to the nozzle.

 

Have spent the most of the time outdoor in the nice weather this weekend, but did get some time working on my project tonight.
Soldered cable on the CornLight and used shrink tube as isolators.
Inserted the CornLight into the mounting hole in the filament fan mount (the other cable in the image is from the fan)
Mounted the extruder mount + filament fan on my printer, and tested the CornLight.

That`s it for today

 

@reprapdiscount

Thanks for the offer. I'm currently down waiting on the new glass bed, since my got chipped.

So, you are saying most of the hotends will clog on out-of-spec filament. My Taulman T-Glase is between 1.85 and 1.95 - is it considered out of spec? It is almost round (0.03-0.05 difference) and not very oval, as others mentioned. I'm not sure if I should give up or keep on fighting it?

 

Earlier on in this thread someone had the same issues as you do with their Taulmam filaments. Taulman stands behind their products and sent them a new spool that was closer to 1.75. Just contact them about it.

 

@Red Submarine,

Yes, I saw that part. That is not what I was asking though... Anyway, I guess I'll start talking to Taulman.

 

Yes, Taulmann took good care of me and replaced out of spec filament. I continue to successfully use the Hexagon with all filaments (though I haven't tried any of the woodfill types). Carbon Fiber from ProtoPlant came out great! I am awaiting some new high strength PLA from Polymaker in China, the upgrade bed rails from r3d, and an out-of-spec test extruder from RepRap discount. I continue to be impressed by the Hex.

 

@1d1, thanks! what is the diameter of your replaced Taulman? Is it nylon or t-glase?

 

@Denys regarding oversize filaments. There are limits to what any extruder will accommodate. My personal experience with the e3d was mixed. It did take the heat, but I had many issues with clogs and rebuilds that I have not had with the Hexagon. Whether that is a function of better filaments, my experience or just plain luck, I don't know. I'm unwilling to reinstall the e3d to find out. I like this experience of successful printing that I'm currently enjoying.
I have o'size filaments in both t-glase and nylon from 1.85 to 1.95. I haven't tried them in the Hexagon.

 

@1d1, thanks, I'll consider hexagon as a replacement. Have you measured new spools you received from Taulman as a replacement? What's the diameter? Is it true 1.75? Is it slightly thicker?

 

Just saw this. On a delta obviously but I like that is has mounts for two fans. Both for the Hexagon and one for parts cooling.

@ Denys; Just under, 1.73, at the beginning of the spool. Haven't checked it since. Nice and round.

 

Got my Hexagon today and have taken some measurements.
Stock hotend 66mm long to nozzle tip.
Hexagon hotend 55.4mm long to nozzle tip.
That's 10.6mm shorter. I haven't heated and tightened it it yet, not sure in the process yet??, but I'm guessing it will probably result in being closer to 11mm shorter. So I need to chop 11mm plus some additional clearance off of my fan duct height, this will be interesting. If you want any additional measurement before I fit this thing tomorrow let me know.

 

@Galaxius, wow, that is so tiny! I'm rather used to a spacious space provided by E3D and relatively easy access to the nozzle even with 2 fans and shrouds front and back... Not sure how I will be able to fit all that with Hexagon
