Quick swap nozzle
Hello
i had 3 olson ruby nozzle (04 /06 and 08mm).
i'm interested on quick nozzle change.
i see we can buy Nextruder V6 Nozzle Adapter. but if i want quick change the nozzle without unscreew the nozzle, i have to buy 1 Nextruder V6 Nozzle Adapter and one hot end for each nozzle right ?
RE:
That's what it looks like on the videos. I was wondering the same. Was ready to order a few adaptors but then realized the hotends are not in the store yet

RE: Quick swap nozzle
I have received the adapter and went through the process of swapping out the factory installed nozzle assembly. The heater block is threaded all of the way through. The adapter screws into the top of the heater block and the standard V6 nozzle screws into the bottom. Getting the heater and sensor wires back into their proper locations is a finicky process and they do need to be properly stowed or the fan door won't close. I'm waiting for some 0.6 mm nozzles to be delivered so I put the factory nozzle back in. I really wish they had gone with the Revo nozzles. I already have two sets and they are far easier to swap. Not to mention the cost. Going by what the adapter cost the individual nozzles are going to cost at least $30 a piece. $30 gets me a 4 Revo nozzle set.
RE: Quick swap nozzle
So I see that the nozzle screws into the heater lock- but what is there to make sure that there isn’t some melted filament between the nozzle and the thing screwing in from above? It seems there could be a gap there that would be hard to purge? Even tightly screwing them together could lead to some material not getting purged?
I’m thinking the backward integration with V6 nozzles is something of a kludge to make people happy. I’ve had issues with the REVO, but the way you can swap a nozzle is pretty slick. The Prusa way is sure to jack up heater blocks and the attached wiring…
RE: Quick swap nozzle
Not sure I follow? You have to do the same with the current MK3 heater block, heatbreak and nozzle and almost every other hotend before that.

Here are some pictures that may help. The standard Nextruder nozzle is one piece with the all metal hot end and screws into the bottom of the heat block. The Nextruder V6 adapter screws all of the way into the top of the heat block and the standard V6 nozzle screws into the bottom of the heat block. At least for the V6 nozzles that I am using the nozzle seats against the bottom of the Nextruder V6 adapter within the heater block so there is very little room for plastic to leak. I plan to use Boron Nitride paste on the threads of the nozzles and the adapter.
RE: Quick swap nozzle
Yes, it should go directly metal to metal (and tightened when hot). It is done that way almost everywhere. Revo and now Nextruder are the only ones that do it differently (that I know about, there are probably already some other similar versions). So I see no "kludge" in the use of adapter, it seems the same as the "standard" 🙂

I agree that Revo nozzles are easier to swap. I was excited about the Revo at first, but then finally did not buy it.
Reasons: Many problem reports with the heater core. No hardened nozzle available - even today...
Insane high prices for a plain brass nozzle! At the first presentations these nozzles should cost "some € more than a current genuine E3D V6 nozzle", so maybe 11 or 12 € /$.
Currently a single nozzle costs 29 € in Germany!
No idea where you want to get a set of 4 nozzles for 30$ ? Probably the counterfeit chinese nozzles ?
RE: Quick swap nozzle

The ObXidian nozzles are finally available, I should get two on Monday.
Won't have much use for them though, as I've ordered a MK4. Well, at least I can print some PCCF parts for the MK4 before it arrives…

No, I bought them from E3D but I somehow got the wrong info on the price. I had a credit from the cancelation of my tool changer order and I may have been looking at the invoice from that order. I see now that the Revo™ 6 Prusa MK3 Edition that includes the 4 Revo nozzles plus the heater, heatsink and wire extensions for £120.80. Yes, definitely more expensive than the Nextruder V6 Adapter. Sorry for the misinformation.

The reason to not go Revo, as per Joseph, is so people can use their existing expensive V6 type nozzles. I guess they care a lot about their existing customers with a stable of expensive nozzles for their farms.
RE: Quick swap nozzle
There's also things like the Bondtech CHT nozzle, which I have, that Revo CAN'T have, because of it's design. I, for one, am very thankful for Prusa making the Nextruder, instead of going Revo. The bimetal CHT nozzle is a beautiful thing, for abrasive filaments, and I do not want to be without it.
RE: Quick swap nozzle
As the load cell is built into the heat sink then I wonder what the feasibility of fitting a Revo is. Hmm.
RE: Quick swap nozzle
Length seems like the biggest impediment?
Do we know anything about the diameter of the tubing on each?
Or the cold side, is there enough material to drill and thread?
For me, changing Only the nozzle quickly, easily, tool less like the Revo would have been a far better solution.
And then having a completely separate compatible assembly to facilitate legacy nozzle compatibility.

They say you can cold swap the nozzles without having to remove the hotend. Seems like the wrench is needed.

I'm not so sure how easy that would be. The nozzle is what is holding the heater block and in my experience your going to need the wrenches if the assembly is hot.

Ya, seems like a wrench is needed to loosen the screw to cold swap. In the video, they use a wrench for that.
At least one doesn't need to unplug wires or tighten at hot to swap nozzles.
BTW, with my revo nozzles, i don't dare touching them at hot either... 🙂
RE: Quick swap nozzle
You understand that nothing is holding the heater block except the nozzle right? First, you remove any filament still in the extruder assembly which will make it hot, second you loosen the thumb screws, third, with one wrench holding the heater block you use the other wrench to loosen the nozzle, forth you further loosen the nozzle until it is out of the heater block with one hand while holding the heater block with the other hand. Probably best to perform a reset after removing the filament and letting the assembly cool down before proceeding to the second step. Speaking from experience. 8^)

Ya, I get it. That's what I do with my Revo nozzles as well: remove filament, wait for cool down, remove nozzle. The Revo heater block has a spring to hold it in place so it kind of stays in place without the nozzle. The Revo doesn't need a wrench, but I still wait for the nozzle to cool down.
Do you remove your Revo nozzles at temperature right after filament is pulled out?
RE: Quick swap nozzle
The one time I tried to unscrew the nozzle while it was hot it seemed that the nozzle was heat seized so I waited for it to cool down. Understand I've only had the printer for a little over a week and I'm being careful not to force anything. I now have the Nextruder V6 nozzle adapter installed with a 0.6 mm nozzle as this is my preferred size for most of what I print.
