[Revo] New hot end system from E3D?
-
@achrn heater with a bit bigger radius would allow for wires from it to emerge directly upwards and you could pack the wire at the back of the heatsink so no problem with airflow. If you look at a lot of hotend installations you will notice that they are bent immediately upwards (or even worse sideways) but luckily the wires are flexible however its still a reliable way to kill the heater if you often mess with the hotend. Actually I think that even v6 hotend install instructions had a warning about that but don't remember clearly... Another thing that I had problems with, is that during catastrophic failures (hits) hotend heater wires would get hit which would be much harder if they were upwards.

It would be a severe blow to sales if the new system did not fit within the outline of the V6.
I can see it being one of the design requirements that the new one fits entirely within the outline of the old one, which for a circular block mean limiting your diameter to the smaller plan dimension of the V6 block. It looks like they've done that (or very nearly so) but making the block diameter sufficient to clear the heatsink really wouldn't. I imagine a lot of people that might change the hot end if it's just swapping the hotend would be less likely to do so if it required a phyiscal redesign of the printhead.

i'm more interested in those new nozzles

They could clone the Slice's design of a removeable grove mount adapter

This will allow backward compatible groove mount and a more modern screw mount.
Personally I would be happy to see the groove mount and the 'hugging' style heatsink fan-mount going away.
What I like about the new design is the round and compact heat element which leaves more clearance to adjacent ducts and other accessories.

sounds interesting. He talked about a partner, maybe this one: https://www.championx.com/products-and-solutions/drilling-technologies/diamondback-nozzles/ which is a Kickstarter, but the company itself is very old.

It was so easy to swap them out
Their tool changer idea didn't create a new trend and I am not sure if the integrated Hemera did, but maybe this approach for changing will. Time will tell.

Apparently E3D worked with the Voron team on a Voron Revo version which is red and also have top screws mount, similar to the Dragon and Mosquito hot ends. This version will not come with a fan because Voron has its own hotend fan assembly.

Since Slice Engineering enforced their patent, the Voron team boycout the Mosquito (e.g. dropped from the PIF program) but they seem to be OK with E3D patent strategy.

@zapta The Revo coldend situation is less of a pickle than the proprietary hotends produced by RUNICE/phaetus under various names, or the Mosquito situation. E3D has a decade of history of building within an open ecosystem. In their blogpost about patents and the Revo they explicitly encourage people to develop cold-end alternatives. It bears noting that little interest has developed in the larger community towards the CC-BY-SA licensed Copperhead design (last I heard it's not competitive on flow, and no-one seems to be interested in iterating on it).

The main difference I see with Slice is that E3D did better PR or are more likable for historic reason. E3D now use legal means to stay the only seller of the heaters, thermistors, and nozzles for their eco system, so allowing people to customize the mechanical interfaces to their machines ('cold end' as they call it) doesn't sound too generous.
Will be interesting to see what creative workarounds China will come with. Personally I am waiting for the Voron Revo, it will be a good fit for my needs.

If anybody is configuring a Revo, E3D recommendations are below.
Since the Voron version didn't come out yet (it mounted using screws, my preferred method), I got the Revo Micro and it seems to work (still testing). I like the small size of the heater because it leaves more clearance between the heather and the air ducts. Also, I expect the silicon sock to hold better than the one I used on a V6 block and had to adjust often.

I used a piece of stainless steel crafting wire to tie around the sock and hold it snugly in place. Never had an issue with it after doing that.

Thanks @Phaedrux, I will remember it next time. I also considered molding my own silicon sock as other did on youtube but never get to it.

CNC Kitchen just released a video in which he shows that the Revo's temperature stability is more sensitive to the cooling fan than V6. Has to do with the structure of its heating core.
