Looks great. Its nice to see development is still going on with the original J-heads, However what sets this apart from a normal hotend? There is absolutely no description on the page you link. How do I even mount it?

it has a standard mounting groove

No answer for the other points? What sets this apart?

Does it only have a single mounting groove? Does this not allow for too much movement around the single groove?

Is it that it's mostly PEEK plastic*, isolating most of the heat down at the nozzle end? I'm new so forgive if that's already common, all the ones I've seen so far were all metal so it is also likely lighter as claimed, but we have no idea if the internals are redesigned as well. There is this in the linked site but little else:

Genuine J-Head™ hotends print consistently faster and are more reliable with none of the issues brought on by all-metal construction.

but beware, also this:

Please note: The maximum operating temperature is 247 degrees Celsius as PEEK will soften at 248 degrees Celsius. Due to many variables, affecting the accuracy of the temperature readings and settings, caution is recommended when extruding at temperatures approaching this limit.

(PLA will require a small fan to provide air-flow through the cooling vents milled in the sides of the nozzle holder.)


*PEEK plastic, looks like tuff stuff!

one of the beautiful things with Genuine J-Heads, theres no fiddling about. no extraneous points where they can leak. they rock solid tiny little hotends that just keep working and working and... working.

they handle all of the filaments most people print with.

I wonder why they are not popular?

one of the great mysteries. best I can tell. people "want" to be able to print polycarbonate so they think they need 300C capability.

at the cost of adding more points of failure and lesser printing experience smileys with beer

I print colorfabb nGen at 250/240c. For this reason alone I need an all metal hotend

It's probably their own PR? Try searching the online platforms for J-head and you'll find gazillions of fake hotends. I didn't know, where to buy the original...

The original creator of J heads getting a screw loose over Chinese copies probably didn't help either...

When the only thing left in your arsenal is to name and shame, and you do, some people think you've spat your dummy out...but then maybe they never had an idea worth stealing...but wait till they do and lets see what they think of it then.
One Day i'll get me a Black Metal JHead...just thought they may get expensive when replacing nozzles & throats.

[www.hotends.com] of course for genuine j-head hotends

j-heads can do 248C

typically you will find that they print at a much lower temp than all metal style due to the way they are designed and materials choice.

Origamib: I believe colorfabb recommends 220-240 for ngen?

Hey Valduare, instead of wondering why they aren't more popular, how about giving a set of bullet points for why a person should choose a genuine J-Head as a hotend?

hotends.com is just a page of buzzwords and marketing speak... If you didn't already want "a J-Head" before going there, there isn't any info there to convince you to buy one. There's very very little to clarify why the more expensive J-Head is better than the competition. confused smiley

there are bullet points on [hotends.com] as well as a datasheet

There are, but neither are particularly helpful when comparing your hotend to the competition. If you think you have the winning design, make it clear why it is better.
At best, all we can gather from the website is that the J-Head 10 is better than the prior J-Head.

And the data sheet... has a mechanical section with no dimensions shown? Not even the hotend width or dimensions for the mounting groove? confused smiley

Personally, I find this hot end or the E3D too big when it comes to their mount and far too long.
Here is what I made, full metal, 46mm from hobgear to nozzle (36mm with the usual heating block). The mount can be a 10X10 Al bar with a vertical heatsink on its side or a 10 mm thick heat sink, laid flat, eventually a small 30mm fan. One 6mm hole, a slit, one screw to press and hold making a good thermal contact.
