Does the V6 adapter work for you?
I have a roll of PETG-CF sitting on the shelf waiting for me to finally print a certain part. I have actually bought the V6 adapter and a Nozzle-X, but as of now I didn't actually mount or test it because I read so many horrible stories about blobs of death and Nextruders covered in plastic. I would simply buy an Obxidian instead and write off the earlier purchase as a mistake - but it's not available and who knows when it will be in stock again...
Now I ask myself if the adapter solution is risky as such or if my impressions are simply caused by the kind of negativity overamplification one may expect in a support forum - while people with issues will be happy to post about their woes, satisfied users rarely write posts about their stuff working as expected.
So, please help me by letting me know if the adapter works out for you or not - and if it doesn't it would be very much appreciated if you could reply and tell me what your problem is.
RE: Does the V6 adapter work for you?
I have now used the V6 adapter and nozzle X from E3D for over a month without problems, I have also switched between 0.4 and 0.6 mm nozzles as well. After installing the adapter, you can just change the nozzle following the "older" MK3 guides: You heat up to 250°C, remove the old nozzle (by holding the heater block) and then install the new nozzle.
RE: Does the V6 adapter work for you?
Didn't work for me and tungsten carbide nozzles. Filament oozing out, the first time I caught it, the second one caused a monster BoD that required me to rebuild the hotend. And believe me, I know how to hot swap nozzles properly, have done it hundred of times on my Mk3s and Minis. On which I run Dragon hotends that have copper hotends. Similar problems with TC nozzles have been reported for the Mk3 with stock hotends, so it seems to be related to differences in thermal expansion, For the Mk4 and XL, I'm now sticking with Obxidian nozzles. Looks like others had success with partial TC nozzles unlike the full TC nozzles from 3D Maker Engineering and Spool3D I was using. For Nozzle X, I don't know. Might be worth a try, if you watch the first few prints. If you don't see oozing, you may be okay.

I've got a separate hotend for ease of swapping, I have a Obxidian V6 Nozzle in it permanently, printing with it all day yesterday no problem.
RE: Does the V6 adapter work for you?
I would love to do something similar, but I only found the hotend bundled with a brass nozzle in the store - as I don't need another brass nozzle, that kind of kept me from ordering. Do they also have the hotend without a nozzle? Do you maybe have a link for me?

I am such a dummy. I now looked at the detail page for the hotend and it even links to the separate parts. 🙂
RE: Does the V6 adapter work for you?
The trick is to use the V6 adapter with a separate hotend by ordering the block, the heat element and the thermistor and building a 2nd hotend. If you follow the instructions and assemble it when heated up once you can swap it very easily
RE: Does the V6 adapter work for you?
I will absolutely do that when the Obxidian becomes available - having that in its own hotend sounds like very good advice.
RE: Does the V6 adapter work for you?
The standard Nextruder nozzles are so easy to change I don't think it is worth having separate hotends for them, I just loosen the thumb screws, then hold the hotend block in a spanner and undo the Nextruder nozzle with a mini socket set. I could not get hold of any hardened Nextruder nozzles, hence going down the hotend swap with the V6 Obxidian.
RE: Does the V6 adapter work for you?
I understand that now. Encouraged by the feedback here, I just decided to just try it out and mounted the adapter. This was the first time I ever removed the hotend as I only swapped Nextruder Nozzles before. My verdict: The person who called this a "quick swap" needs to be severely punished, and the person who came up with that cable canal design deserves to join the punishment.
RE: Does the V6 adapter work for you?
Don't bother with replacing hotends. Just do as JP Guitars said, replace nozzles by holding the hotend in place with a wrench. With the fold-away fan of the Mk4 it is super easy, and no need to futz around with the cables.

RE: Does the V6 adapter work for you?
For swapping Nextruder Nozzles, that is true - and that's exactly what I've been doing all the time because I read in one of your posts that this is the way. 🙂 I'm just considering getting the V6 adapter its own hotend.

Which is why I leave the wires exactly where they are. There is no reason to touch them.
The only reason to fiddle with the wires is if you want to swap the whole hotend, and that is only necessary if you want to use a V6 converter

Using with a diamondback PCD V6 nozzle, no leak problems, ASA, PLA, PETG and PETG-CF.
I installed the adapter in the heat block, tight. Then the V6 nozzle. Assembled, heated and did final torque on the V6 as outlined.
RE: Does the V6 adapter work for you?
it works for me I wanted to get the unobtanium one but prusa could not sell me one so I am using the adapter with other hard nozzles.
I did need to screw the adapter all the way into the aluminum block and firmly bottom the hardened nozzle into the adaptor. Hard to believe how poorly prusa supports their products.
maybe when joe gets back from maker fair he will start supplying wear parts
RE: Does the V6 adapter work for you?
The cable channel is stupid. Very poor design. We this type of failure when the design is done by someone that has no idea what the end use is.
RE:
I found that the V6 adapter worked fine with PLA but as soon as I tried printing with hotter temperature materials like PETG, ASA etc, the hotend started leaking out of the top around the thermistor and heater cartridge wires. NozzleX was the nozzle I tried using, haven't tried any other nozzles with the V6 though!
And yes I assembled and tightened the V6 as per Prusa's instructions. I've tried retightening at max temperature without any success. I've disassembled and cleaned everything up and reassembled the V6 adapter three times now without any success! Out of frustration I disassembled everything once more, retapped the threads in the hotend and reassembled the V6 adapter this time with a small amount of thermal grease before reinstalling once again on my MK3.9 and performed the tightening procedure at 275 degrees. Still no luck. I have discarded it and chalked it up to a $30 learning curve. I now use the Prusa Obxidian nozzle on one of my MK3.9's and when they come back into stock I'll purchase another one for my other Mk3.9. I'll just use the E3D nozzles on my MK3S+ machines.
Your experience may vary and I may have received a dodgy adapter, who knows, but after many attempts to make this work I decided that it's not working for me and Prusa's Obxidian nozzle works great with ALL materials, so it is going to stay on my machine full time.
