Confirmed: Sovol SV08's New Nozzle is Screwed

[@MaximalistWorkshop]

There's an OFFICIAL threaded hotend for the SV08!! Check out my new update here: kzbin.info/www/bejne/g2Gro5hviLuch5Y&ab_channel=MaximalistWorkshop

[@GoatPrint]

Thanks for the information. I'm waiting for my unit to arrive.

[@RocktCityTim]

Thanks for diving into this. I am looking forward to your Revo mod vids!

[@MON5TERMATT]

I have just received the new nozzles with the grub screw.

[@MaximalistWorkshop]

Nice!! Hope it works well for you. Please keep us updated if you run into any issues with it!

[@funwithrpis3281]

Waiting for parts to build the Xenomorph setup from Nadir because that setup is just straight up sweet looking with the screen.

[@mr.highschoollocksmith6080]

Sovol is handling it very well IMO, they understand the need to please the customers who bought into them and they are willing to make things right if it goes wrong. They definitely took a gamble with the proprietary nozzle design, so i hope they realize that wasn’t the right move and hopefully offer their nozzles at a discount or perhaps assist with a mod that allows users to switch to more common nozzle/hotend types.

[@mykola-drabiv]

Hi, thanks for the video and nailing down the problem. I have completely same issue - broken 2 nozzles that came with the printer. Additionally second nozzle damaged printing surface and yes I printed only PETG. After a week of communication with Sovol and sending them photos of the damaged parts and photo of the serial number of the printer they finally send me replacement parts. Since the parts shipped from China it will take up to 3 weeks to deliver :( . While I waiting the replacement of the standard nozzle I decided to buy on Aliexpress in Sovol official store the nozzle made from the hardened steel and has thread so it will not have same problems as the original nozzle shipped with printer.

[@MaximalistWorkshop]

Good call. I have a video backlogged about the threaded hotend, but as a preview in case you haven't seen it mentioned elsewhere: it's compatible with Neptune 4 Max nozzles, so it unlocks a lot of options. Testing a ruby tipped nozzle on ours now.

[@yertelt5570]

I just got my machine Thursday, 7/18, it appears as though it has the original chrome nozzle. I just finished printing the top riser for the enclosure kit, four pieces, about four hours print time each, in PET-G. It was my first time printing PET-G so I used the stock factory profile from Sovol. No issues.

[@jonathonodonnell253]

I contacted Micro Swiss and they are apparently going to be designing a flow tech and revo(maybe?) for the SV-08. They like myself are just waiting for there’s to arrive.

[@MaximalistWorkshop]

That's huge news!! Thanks for sharing. I'm super excited to test them when they come out. I wonder how their Revo design compares to Jonathan Levi's

[@3dpathfinder]

Micro Swiss is coming out with a Flowtech Hotend Upgrade for use with their CM2 Nozzles and Diamondback. 3D Jake also has Hardened Nozzles for the SV08

[@TheCrashcore]

I've been printing PLA for days with around 25mm³ (max flow set to 27, as ~29 was the point where the flow test failed)with no problems at all, nozzle didn't move at all

[@sprlpy318]

Nice work ))

[@MaximalistWorkshop]

Thanks!!

[@talentedmrripley9057]

Can you provide some details on the specific options you chose when ordering the Revo adapter? Specifically, what type of aluminum? Did you choose threaded holes? Tolerances? Surface roughness? For the finish did you do bead blasting and anodizing or just anodizing?

[@Timo-nm1ui]

thank you

[@oldtimeengineer26]

I just got mine today and it came with a damaged cable on tower 4 and also on the base plastic for tower 4 was bent and I could not even get it in. I took my heat gun and plyers and straightened it out and got it installed repaired the cable and it is now printing. So they really need to up there QC.

[@oleurgast730]

While my SV08 is not delivered yet, I already got the coldend for using Revo nozzles designed by The Next Layer and custom made by PCBways. Actually all new fast printers use nozzles with high flow (bigger meltzone than the good old V6). However, while this is good for max printing speed, you can not easaly attach an MMU (Filament changer, like the ERCF). Due to bigger meltzone the filament tip after unload is not be ready to be reliable been loaded again. This is the reason Bambulab and others use cut&poo for their printers. Wich is a waste of filament and over all printing time. Prusas MMU2/3 do a much faster filament swap. Both the old mk3 (esp if upgraded to a standard Revo) and the mk3 Nextruder use standard flow hotends. While the mk4 is only about half as fast as an modern CoreXY like the X1C or SV08, on multicolour the over all print time is much faster. So if you plan to add a filament changer, imho a Revo hotend is the way to go anyways. Use a Revo high flow nozzle for normal prints, use a standard flow for using multicolour. So no cut&po needed, just a very smal prime tower (+ wipe2infill or wipe2object). Of course, if you do not have Revo hotends and nozzles on other printers, upgrading the SV08 can cost more than the printer itself (one ObXidian nozzle about 70€, a high flow nozzle about 60€, standard flow about 30€, heater core 60W about 50€, custom coldend about 45€; if you want 0.4 and 0.6 ObXidian + 0.4, 0.6 and 0.8 high-flow + heaterCore high flow + coldend, this is about 425€). But if you have most nozzles you need anyway, an upgrade is much more affordable.

[@MrBaskins2010]

that revo looks great. bambu compatibility shouldve been a day one feature but sovol is stubborn.

[@grigoryshokhrin494]

I love how they say new design. They took a already established designed and butchered it by making the nozzle press fit. Trianglelab has been making this “design” for some time now, except they actually made it correctly.

[@DracoDragon369]

I'm curious how open they would be to giving a discount to people who just was to opt out of their hotend and go with 3rd party. Cause I'd gladly pre-order it again if I got that option so I can get the revo e3d hotend off the bat.

[@grasstreefarmer]

Settings won't change anything. If the nozzle has manufacturing problems it will fail eventually no matter what, and if it doesn't have manufacturing problems no ammount of flow rate will ever be able to push a properly press fit nozzle out. Its a silly red herring obsessing about what setting are being used. Depending on the manufacturing method the nozzles are either forced in with hydraulics or the nozzle is cooled with something like dry ice before it is inserted so it then expands and is permanently placed. A stepper motor pushing on a plastic filament is a tiny percentage of the force needed to seat or unseat an interference press fit ... unless it has manufacturing tolerance problems. The pictures of them just sliding out means they are significantly undersized. If it was a design problem there would be far more examples than there is.

[@3dpathfinder]

Im printing PETG just fine, yet I use Aceaddity PETG which prints wonderful at 230-235, just printed a new toolhead cover at 15mm/sec

[@eaman11]

lol both my ender3 and N2s with CHC nozzles do 20mc flow with PLA, those hotends cost 4$ on Ali!

[@MaximalistWorkshop]

Sure thing - if I'm understanding "mc", that's probably not high enough flow for the SV08, though. The SV08's hotend is rated at 30 cubic mm, and speeds as low as 420 mm/s using a .4 mm nozzle width and .2 layer height probably uses all of that volumetric flow. Since the SV08 is meant to be able to move as fast as 700 mm/s, it arguably needs something more powerful than even its stock hotend. That said, there's no reason a hotend couldn't be designed to run at 50 or 100 cubic mm using a CHC/v6 nozzle

[@eaman11]

@@MaximalistWorkshop Ye mc is short for millimeter cubic. Don't forget line width and stuff like solid infill: you do ~0.6mm LW there, also vase mode.

[@airheadbit1984]

New issue: Extruder planetary gears striping. While printing sv08-top-extention-lit-back-left.stl after 1.5 hours, the filament stopped extruding, I aborted the print and tried to retract the filament, nothing happened, I disassembled the hot-end and found the filament had been forced into a short piece of PETF tubing between the extruder planetary gear and nozzle, I replaced the tubing but when I tried to turn the wheel of the extruder it only traveled a 1/8 of a turn, this was with no filament. Disassembling the extruder reveled the missing teeth on each of the three gears. I was using PETG with a Sovol dryer, the same setup I use on my K1. I just tried to order a new "SV08 Original All Metal Planetary Direct Drive Extruder" but it appears to only exist in China, weeks instead of days...

[@sirwarrior]

I swear I'm the only one who likes their SV08.

[@MaximalistWorkshop]

What makes you say that? I love mine - it's why I keep making videos about it and trying to get it to work. Wouldn't spend nearly as much time on it if it wasn't my current fave. Setting the nozzle issue aside, loads of others have been reporting great experiences.

[@sedalespencer69]

I mean.....its still the cheapest you can get a "voron 2.4".... And the printer itself is still open source, therefore we can use practically any toolhead w want.

[@Ughmahedhurtz]

Maybe they could have just reused an existing, common, popular, high-performance, NON-BROKEN design so people didn't have to replace major parts of brand new printers? /smh

[@MaximalistWorkshop]

Agreed, though I wonder if they realized this would happen given that it didn't with the T300. To the extent they were able to cut the machine's cost by using a design they already had on-hand that was working for them, I think all power to them because it means (at least in theory) the printer's cheaper for us. That said, if they were going to take this approach, more testing on their equipment and profiles before shipping everything out may have caught this.

[@Ughmahedhurtz]

@@MaximalistWorkshop The "more testing" part is probably the weak link there, I'll agree.

[@syns369]

WTF, my default profile for the sv08 has 21 mm3/s of max volumetric speed

[@MaximalistWorkshop]

For what material? With ABS, that's normal.

[@syns369]

@@MaximalistWorkshop with the pla profile

[@MaximalistWorkshop]

@@syns369 That's fine. That's the same profile we're using here. The original hotend is generally rated at 30 mm 3/s, but it won't be able to do that with every material under all conditions, so Sovol set a more conservative number in the PLA profile. You can run a calibration test to see what the hotend can actually do with your filament on your machine. The newer hotend designs should all be able to handle a decent volume with PETG - it's just the very first iteration couldn't handle more than 8 or so because the parts weren't machined correctly.

[@syns369]

@@MaximalistWorkshop ok I sée thank you , however I did reduce the flow to 18mm/s ans increased temperature to 240 for pla otherwise It got clogged everytime , maybe it has to do with the hotend design

[@newCrysis]

My opinion of Sovol, goes down daily.

[@marshallwebber9682]

I was so close to buying an SV08...and then I remembered my engineer father's best piece of advice, "Never buy the first production run of anything." We'll see about the Sovol SV08...in 2025. (Assuming we can still buy anything from China in 2025.)

[@Splarkszter]

Buy the P1P. It's even cheaper. 500 vs 580

[@samlcyo2]

Smaller tho. I bought the sv08 for the performance and the size ​@@Splarkszter

[@erikhill6037]

​@@Splarkszter The P1P is a good choice as long as you don't need the build volume. I have an X1C as a my main printer. I want to print face masks. Sure I could cut them up, but that would add more work, decrease strength and increase my processing time. I am looking at something like the SV08 or a Voron with a .08 to print the large bases.

[@francistaylor1822]

@@Splarkszter Smaller and not open source. The good thing is if this is the only issue, the nozzle is a consumable anyway.

[@Splarkszter]

@@francistaylor1822 It's not the only issue. There are reports of some parts not fitting and such. This printer needs at least half a year more.

[@KJMcLaws]

What are you doing different at 2:48? Your audio is much more understandable. The rest sounds poor. Like you have the mic too close and then it's clipping. I don't know exactly how to word it but the please put this on the website part sounds so much better than the rest of your video.

[@MaximalistWorkshop]

Not sure - realized halfway through recording this vid that my mic is broken, though, so I'll do some testing and tuning when I get the new one in. Thanks for the feedback!

[@KJMcLaws]

Your mic being broken is also a good description lol. If that's all it was, that could make sense. I liked the two videos I saw you put out on this topic. The audio was challenging to get past. I'm looking forward to more high quality content.

[@popscorn66]

what thermal paste or glue are you all using on these hot ends. I am swapping mine out as my current one keeps under extruding like there is somethin in the nozzle. I have cold pulled it and i can push filament through easy but when I run 100mm test I get only about 75-80 through. I have tried using it like it is by upping the flow but still no dice. They sent me a second one but pulling apart the original there is white thermal glue or paste that semi hardens I want to put the same stuff or similar on just want to hear what you all are using.

[@The_Privateer]

They really dropped the ball by having a closed source proprietary hot end. Especially when they scream about how "open source" they are. Hell, even use a thrird party (somewhat) closed source hotend/nozzle system thats like..... Revo compatible

[@jzagaja]

8mm3 really? stadard PLA is 21 while flow test in Orca says >30mm3 easy

[@MaximalistWorkshop]

@@jzagaja Yeah. If there was no problem, it wouldn't have been worth making a video.

@@MaximalistWorkshop I received nozzles with that additional thread, what's the purpose? My stock old nozzle 0.4mm 30mm3 petg no problem tested.

[@MaximalistWorkshop]

@@jzagaja The purpose of the grub screw and threaded nozzles is discussed thoroughly in this video and others on the same topic. It's great that you were able to get whichever nozzle you got to work to work, but not all of Sovol's stock nozzles have been without failures.

I don't plan on using PETG so hopefully my SV08 should be good to go But is good to know just incase i do end up using PETG. Thanx 4 sharing Bud.

Thank god I bought a BambuLab instead of this

[@tombo7719]

Sovol is like Creality. Many companies are like these 2. Cheap is expensive. I am an SV06 owner with all kinds of issues and only used it about 9 times.

[@riba2233]

[@Bapate-rh9be]

Who the F pressfits anythign in a system that undergoes rapid heating and cooling cycles? Also M6 Nozzles are abundand, and even nozzles with integrated Tube are already a thing?

[@MaximalistWorkshop]

Aren't Bambu Lab nozzles press fit? I remember seeing similar failures to the ones Sovol is having now on the Bambu Lab X1C around when the X1C was released. I think it might be press fit on the Adventurer 5M series, too. The new K1C unicorn hotends have a press fit insert, as well. And the Sovol nozzles do have an integrated heatbreak

[@Bapate-rh9be]

@@MaximalistWorkshop Yes, as you said: Similar failures. Depending on the heating rate the outer component may be tighter, which may cause slight creepage/deformation, or looser, which then opens the connection. It is not impossible to get this under control, however it is difficult and - why? M6 Nozzles work fine.

[@MaximalistWorkshop]

@@Bapate-rh9be They're cheaper. Also, putting the heater block directly against the filament instead of having a nozzle in-between them can provide improved thermal performance and thermal stability. Not saying press-fit nozzles are a good thing, and I agree with you intuitively, but Bambu and others did have at least some reason to switch. Since Bambu doesn't have this issue anymore and hasn't in a long time, it seems fair to say that press fit nozzles can be fine. Also seems worth pointing out that none of the press-fit nozzles from Sovol except for the original silver ones that Sovol said had QC issues are failing, which at least suggests that the design was fine. Otherwise, we'd see bronze nozzles popping out of the hotends, too.

[@C650101]

Not surprised the hot end is crap. If I were to buy this, i would plan on replacing the whole toolhead. But i will not buy this. Toodon just needs to come up with a Canbus version of troodon 2 and kick this to the curb.
