Other nozzle sizes available (not using adapter)?

Will there be other Nextruder nozzle sizes available (ie: 0.6mm) without having to purchase the adapter? Or is the only exception to use the adapter for any other nozzle size besides the 0.4mm one that comes with the MK4? Currently, I don't see other Nextruder nozzle sizes available on the website.

They said in a video that other sizes would be available.  I even thing think they said something about a high flow one.?. Can someone confirm this?  ...I'm eagerly waiting to be able to order a larger nozzle.

RE: Other nozzle sizes available (not using adapter)?

WEll, I have on hand a small stock of alternate nozzles, including hardened steel 0.4 mm and a olsson Ruby.  I have in mind to start a project that will likely use CF filament, and I will need to use a hardened nozzle.  But the guidance for CF filaments generally suggests using larger size for better results (reduced clogging). So, I think I need (say Hardened Steel 0.6 mm). But that size unavailable in the prusa store in regular nozzles.
Thats a roundabout way of saying that I'm another that would like to see alternate nozzles available in Nextruder type sooner rather than later.  But particularly Hardened Steel type and larger sizes.

Prusa have the Adapter for old Nozzles fitting onto the Nextruder, but do not offer spare parts heat blocks. Whilst swapping nozzles on the Nextruder is quick and easy if the replacement is also Nextruder type, its not so easy if you are wanting to swap in/out the older type nozzles. Got to get out a pair of spanners, and it looks like it would be easy to to get leakage around the heat block doing that.  So, I would prefer to have the adapter permanently fitted onto another heat block with permanently fitted alternate nozzle ready to go, not having to use that spanner too often.

Thats a roundabout way of saying that I'm another that would like to see alternate nozzles available in Nextruder type sooner rather than later.  But particularly Hardened Steel type and larger sizes.  And I'd also like to see the Nextruder's heatblock also added to the spare parts shop.

RE: Other nozzle sizes available (not using adapter)?

I ordered one of the 0.6 nozzles as soon as the web site showed them as available.  My MK4 is still weeks away from shipping.

The "quick change" feature provided by having a full assembly (nozzle, heat block, heater, wiring, plugs) is attractive -- but also expensive since it requires duplicating other parts (heat block, heater, wiring, plugs) for every nozzle.  Given that the nozzle is "one piece" with the heat break and can therefore be cold-swapped, it will take only a moment to un-screw one nozzle from the heatblock/heater and screw in another.  I won't be swapping that often, so I decided to go with just the nozzle instead of another full nozzle+heatblock+heater+wiring assembly.

I screwed it up.  When they were released I just bought what I needed ASAP so I didn't get stuck in a buying queue.  I got 3 nozzles, but didn't realize these arent quick change like how the machine was marketed.  You gotta buy all the individual bits and assemble it yourself to have a quick change nozzle.  Sad.

I raised this issue with prusa support. I pushed to have them make a kit of nozzle + tube +  heatblock available. My reasoning is that its tedious and error-prone to have to swap out the carefully adjusted nozzle from the heat block and the heat block is inexpensive. so the easiest swap is the whole assembly and least risk of causing damage to the delicate heatblock wiring. 

I want them to release:

-0.6 mm brass nozzle on native nextruder long tube.

- 0.4 mm and 0.6 mm steel nozzles on native nextruder tube.

Because print using larger nozzle can be useful for large prints you want to go quicker. And steel nozzles an absolute requirement for printing CF impregnated filaments.

What was their response?  I have *assumed* that was the plan -- i.e., to eventually sell a complete assemblies (nozzle+tube+heatbock+wiring+etc).  Did support indicate whether that will eventually be the case, or that customers would have to buy individual parts and build their own assemblies?

They said they already thought of it, and should be available in the online shop in a few weeks, along with others parts for Mk4 and XL.

By the way, I already know that having a steel nozzle sitting on the end of the tube (a composite of Brass, Copper) might be asking a lot, but you never know. The old technique of "brazing" or "silver soldering" type of welding might work.

Tedious, perhaps, but how is it "carefully adjusted" and "error-prone"? I could see that describing the MK3/Mini nozzles, because you have to hot swap the nozzles, and the heaterblock is threaded onto the heatbreak, and the nozzle threaded into the heaterblock, and if the heaterblock is threaded up too far the nozzle won't touch the heaterbreak and you'll get leaks.

But MK4 you drop out the assembly, then unscrew the nozzle, screw in a new one, and put the assembly back in. It's not hot, you don't have the unusual double threaded connection of the prior nozzles, you aren't working on the nozzle while it's attached to the printer, etc.

I’m referring to the procedure to attach a regular nozzle to the adapter they supply. Just like the Mk3 I foresee there will be oozing issues with leakage from the nozzle and tube inside the heatblock. Prusa support informed me that using a steel nozzle its entirely possible to cross the threads in the heat block.

the instructions already indicate you must first clean out that tube before the nozzle can be removed. that alond is enough to deter folks from swapping nozzles on assemblies using the adapter. which is why I have bought several of them, but additional heatblocks are also needed.
