[Revo] New hot end system from E3D?

I am looking at this new system and I am not sure what I think about it.

I know they don't have hardened nozzles yet (to come, I am sure) but when you bugger up a nozzle with abrasive material or just for the heck of it, it seems like it will be a lot more expensive than just changing the nozzle.
I have also had sensors malfunction (although they were clones) and just shudder to think what it would cost to replace the heater/sensor module.

I lean towards liking what I see but I guess we will have to see what pricing is like. I can't honestly see much of an advantage over my Dragon hot ends.
It will be interesting when first hand use reports show up on the web.

From that webpage:

All the cool innovation you see in Revo is still going to cost you significantly
less than anything else you’ll find in the market of this quality. In fact, for
around £100 (that’s roughly 120 USD) you’ll not only get a full Revo HotEnd 
you’ll have all four Revo nozzles to swap out.

If they can sell the full hotend and four nozzles for US$120 it seems like pricing for replacement nozzles should be reasonable.

But as you said, we'll have to wait and see...

@diy-o-sphere, the new E3d stuff is 'announced' but not yet 'available'. So they are all guessing there too

@jens55
There are some beta testers,,,,

I must have missed that part ..... I follow that Discord

@diy-o-sphere Which channel?

@diy-o-sphere Thank you.

Am I understanding this correctly -- if you remove the nozzle, the hotend comes off as well?

Without cheap clones and imitations, at this price it will be a niche product, like Slice's. Weather we like it or not, it's the cheap Chinese products that create the wide adoption and a rich eco system.

@plasticfactory yes!

...dream on Maybe it's like buying an inkjet printer for peanuts and later spend $$$ for new ink.
It's the classic Rockefeller method: hook'em up with a cheap lantern, then sell petroleum for grands...

They're using a PTC heater element, wondering how that will cooperate with RRF PID tuning?

I wonder whether the coupling between heater element and sensor (all in one integrated unit) will be tighter than between heater element and nozzle (noting also that the nozzles seems a loosish fit in the heater element - I see a spring apparently to keep things from completely loose).

But I expect E3D have some idea that it works...

If it wasn't for cheap clones, the genuine original product would be cheaper and need not be a niche product. It's the cheap clones that drive up the price of the genuine original and stifle innovation. It costs money to design and develop a new product. That R&D cost can be amortised over a number of unit sales. Let's say for example that it costs a company 10,000 in R&D costs to develop an idea. If that company can sell 10,000 units, then they would only need to charge 1.00 per unit to get their costs back. But if they only sell 100 units, then they would need to charge 100.00 per unit just to get their R&D costs back. So when cloners come along and steal their ideas, they have no such R&D costs, so they can undercut the original, which drives down sales of the original making the cost differential greater.

Cloners are not interested in developing new products - why should they when they can steal other peoples ideas for nothing? So why would any company spend money on R&D if they can never get that money back?

A case in point. I've spent 2 years attempting to develop a 6 input hot end - probably about 10 hours a week on average. That's 1000 hours of my time @ say a modest £10 per hour = £10,000 for labour. Then I bought a small lathe and milling machine plus tooling so another £2,000 or so. So if this ever went to market, I would want get that £12,000 back. But I know that I could never sell enough units at a reasonable enough price to recoup that cost because a Chinese cloner would steal my design and so could sell them for less. So if ever I get this thing working, I will take the design to my grave rather then let a thief profit from it.

I often wonder how many other innovative ideas are sitting around which will never be bought to market for the same reasons.

@o_lampe I've had no issues tuning my beta unit

I did not notice any difference to "normal" heaters, it worked just fine.

When you run the Duet's PID, did it report a lower 'max temperature' due to the PTC?

The PTC is represented as a safety feature that limits the max temp in case the power mostfet get stuck in on state.

From what I've read from devs on the Voron discords who have had pre-release versions for quite some time now, I will probably get one as soon as I can. They are very happy with them.

I can pay a bit premium buying from a European company as with Bondtech and Duet as long they offer functionality and just aren't patent trolls or marketing...
