Chances of a Revo adapter?

I know the new design makes the Revo's big selling point of quick change nozzles a mute point, but I have to wonder if anybody thinks there will be a Revo adapter available eventually. I have a decent collection of Revo nozzles that I don't want to give up on, and only have space for one printer. Also, with Prusa working with E3D for their nozzle, and that work beginning before the Revo was launched (maybe even designed?) I'd have to think they considered this idea.

A Revo nozzle change would likely still be faster... maybe by 30 seconds.

I reckon E3D will come out with something… or someone else will design an adaptor for it. Or even Prusa themselves might introduce it in a later revision.

Perhaps Prusa was just too far gone with their own implementation before Revo was a thing or they didn’t like the patented design.

RE: Chances of a Revo adapter?

I hope something like that comes to fruition.

Hot take so far, the Prusa implementation does have backwards compatibility, but at the expense of a "reasonable" cost effective hot swap nozzle.

It appears the wrong engineering goal was prioritized IMO.

RE: Chances of a Revo adapter?

You would lose the load cell for a slightly faster nozzle change. Doubt it's going to happen, as the load cell is far more important.

RE:

The chances are 0.000%

 

The is no way the Revo nozzles could be adapted to the Nextruder as they are significantly different.

 

The only option is the V6 nozzle adapter. 

 

E3D were part of the design team for the Nextruder hot end and are the ones that manufacture it.

 

Both were being developed at the same time.

The load cell isn't part of the nozzle.

Correct, it’s part of the custom heatsink. However, the Revo is much more than a nozzle, it also requires a custom heatsink that has the correct layout and threading for their custom heat break.

RE: Chances of a Revo adapter?

There are different heat sink designs with different flavours of the Revo already - granted quite similar. But there is nothing to stop E3D producing a Nextruder based Revo which accepts the Revo nozzles.

They made the Voron Revo for instance.. and I would imagine those owning a Voron and wanting this is less than those in the Prusa user base.

So it may be unlikely but it doesn’t remain they won’t.

They would have to produce a heatsink with a load cell in it, to remain compatible with the Nextruder. Not impossible and probably not too expensive. I do prefer the Revo solution to the Nextruder, since I can easily remove just the nozzle and heatbreak from the Revo, whereas for the Nextruder, the heatsink also comes along for the ride and you have to plug/unplug things into the daughterboard. Here's hoping E3D is willing to go to the effort.

RE: Chances of a Revo adapter?

Looking at photos I am a bit confused as to what the heatsink actually looks like. It appears that the nozzle goes into the heater, then slides into a metal piece, and then clamped on with the thumbscrews. This metal piece also holds the gears, extruder, and the idler screws. Since I don't have an MK4, and can't find anything that shows this piece on its own, or even without the heatsink fan... I have a feeling that everything is one piece and it would be unlikely that they would make a Revo adapter for this if they have to replace that entire part.

Anybody with an MK4 able to remove the hotend fan and take a photo to see what's behind it?

Only place that I've seen it so far is on CNC Kitchen's review around 6:09.

Thanks! Yep... I doubt a Revo adapter (that uses existing Revo nozzles) will be forthcoming. Unless they produce this entire piece with a load sensor, and a method of attaching a longer metal tube to match the new Prusa nozzles.

That's sad... my ObXidian nozzles were sent just a few days after the MK4 was announced and I didn't cancel them.

One solution would be to build the remaining tube length into the heat sink. Still, seems quite complex for something that will likely not generate a ton of market share for them. The incentive to upgrade to the Revo will be less on the MK4 than on the MK3S, because it will already be fairly easy to swap nozzles (not as easy, but still pretty easy).

I could see them building a tube with a threaded end to receive the Revo, and then that goes into a modified heatsink, and clamped on like normal MK4. This way the tube can be removed via the usual MK4 nozzle change if needed, but the Revo is handled the typical way. That modified heat block probably wouldn't be cheap though.

Before my Revo I was getting a lot of leaks, and tried for so long to solve them to no avail. I worry that the Prusa adapter with nozzles will be similar, plus their instructions for nozzle changes still includes tightening when warm, which is a huge advantage the Revo has. So to change nozzles relatively quickly, you need a heat block for each one. I've had great luck with the Revo and a bunch of sizes and now ObXidians.

RE: Chances of a Revo adapter?

I can see perhaps having to drill and tap the existing heatsink. Perhaps a third party mod? Difficult to say without getting our hands on one of the heat sinks to take a proper look at it.

Perhaps Prusa will release pre assembled nozzle adaptors or even full nozzles with hardened steel, tungsten carbide, diamond back etc greatly reducing the need for the Revo.

RE: Chances of a Revo adapter?

I still don't have my MK4 shipped, but I looked at it in several video and photos, and I realized that Nextruder behave basically like a Revo.

  1. The Nextruder nozzle should be unscrewed using an Allen key like the old nozzle, and has no nice rounded handle.
  2. Revo has a nice rounded handle covered by silicon, easy to screw that do not requires the use of an Allen key.
  3. The length and shape of the two is different.
  4. But the behaviour is the same: both two keep the melted filament inside, so there is no contact between the melted filament and the heated block thread, that is always well clean or with conductive grease. As result both two can be unscrewed cold and replaced.
  5. I did not purchased any adapter because this break the rules, and will allow melted filament particles to dirty the thread, since sooner or later the two parts (adapter and old nozzle) will be mounted wrong, not in contact, and the melted filament will dirt the thread making difficult the change, and reverting back to the old time of the old MK3 nozzles hot changes.
  6. I will keep the REVO nozzles for MK3S+ and I will use the Nextruders on the MK4.

What I did not understand is why Prusa presented the Nextruder in their campaign always removed together with the heat block, even disconnecting the cables from the extruder daughter board. I mean, I know that the fan like a door, and short connectors, are nice, but on the everyday life, users will just unscrew it, may be holding the heat block with a pliers to avoid to force on the extruder structure.

What really surprised me, was the cost: more or less the same (around 29.90€ for a single Nextruder nozzle against 26.99€ for a Revo), so I have no special interest to use all Revo. I hoped Prusa would have sold Nextruder nozzles for less (e.g. 12/15€), but they didn't (probably due to the high cost).

Sorta the same... but not really. The heat block is only attached to the printer via the nozzle, so unscrewing the nozzle means the heater is hanging by its wires only. Thus, Prusa says to remove the whole thing, then remove the nozzle, then reconnect everything. The more times you do this, the more times you risk a breakage of the thermistor or heater wires.

Revo is just so much simpler, no tools needed, no opening anything, no disconnecting wires... just unscrew by hand, and screw new one it. It really is a superior method of nozzle swaps. I am much more inclined to use different nozzle sizes because of Revo.

RE: Chances of a Revo adapter?

While not a 1:1 replacement you could fit a Revo extruder to your prusa and get a revo to V6 adapter like this:

https://www.indiegogo.com/projects/revo-to-v6-adapter-expand-speed-up-cut-costs/x/33605500#/

That way you could use your own V6 nozzles while still having the quick change features

That adapter does not solve the problem in this case. The MK4 extruder and heatsink is a completely new design. That campaign only lets you adapt a V6 to a Revo system giving you access to all the V6 nozzles.
