Yes, adding a screw to the heater block is something that some folks are trying. Voron has been central to their marketing from the beginning, but it seems like they really didn't test the T300's nozzle with PETG with the SV08's accelerations before releasing the machine. Based on their email to me, I had understood adding a screw is what Sovol is doing and that this new design was in testing - it's discussed in my update video linked in the description. However, they have since publicly said that they don't think it's a design issue and they're checking with their manufacturers to confirm that tolerances are fixed. That statement is posted on my KZfaq profile. At this point, I'm not sure what the plan is.

Its typical for a lot of manufacturers from China. Its not good at all, and relies on goodwill of customers - then again Prusa even did the same thing to some extent

I got an update - I'll post a new video as soon as I can!

Or a screw or literally anything else hahaha. Since they never had any issues with T300 users, it just never occurred to them to test whether the nozzle could handle SV08 accelerations with all materials.

@BillBollinger-i4v Dope tip - thanks! I assumed this was fine because it came with a hotend I bought, but you're right. Probably worth some testing and a vid.

Agreed - fwiw, the Revo adaptor is available from PCBWay (though surprisingly expensive; waiting for mine now), and there's someone in the community who designed a V6 adaptor for which they're just trying to find a manufacturer now. As expected from the maker community, new alternatives are popping up every day!

@@MaximalistWorkshop How much was yours? Everywhere I read it's surprisingly expensive, but I never saw a price.

@froh42 mine was originally about $220 or $230, but they dropped it down to about $140 because some of the custom stuff I asked for wasn't possible. I've heard less personalized units go for more like $80 or $90.

Of course you pay at least two times the price of a SV08. Mind that the SV08 i completely open source and soon there will be many, many mods in order to use a alternative nozzle like a V6, volcano or Bambu lab.. If you're definitely not the handy person to do well documented mods, you probably also need to stay away from a Voron? So, that's my 2 cents

Look into the troodon 2.0 pro. It’s what the sv08 wants to be. Despite what Sovol has said the sv08 is not open source beyond releasing cad models. Most parts are proprietary, Voron mods do not work on it, and even the klipper it runs on is custom to Sovol and has not been made available.

@@chemicalwaffle9220 Many parts are standard like idlers, pulleys, a makerbase clone board, it's a ery simple printer. The CAD model is the only thing I need to easily building my mods.. I've been building my own 3d printers for 10 years now, and the SV08 might be the first of the shelf printer I buy. Goal is the equip it with a decent tool changer..

@@winandd8649I hope you are successful in that project. That would make the sv08 much more interesting. I think it could be a good base for modding like an ender 3. I just wish they spent more time on QA. I have been seeing so many issues online that were avoidable.

@@chemicalwaffle9220 Thanks, indeed a nice platform for modding. All issues there might be with the SV08 can all be resolved. Cheers!

Thanks!! More users are affected - lots of posts from them on social media now, including in the comments here it seems. I agree with you that Sovol's customer service is top notch, especially in this field, and I'm sure they're working diligently to address the issue. It would just be good if they made a public statement about it so that people can stop using PETG on their machines for now. Weirdly, it seems like this is only happening with PETG - I haven't found any cases involving ASA or ABS. I think I figured out why the nozzles changed - I'll follow up with an update video ASAP.

@@MaximalistWorkshop Saw your video yesterday, dropped my SV08 nozzle and scratched up my PEI sheet today. I just wasn't sure you were sarcastic when you said the nozzle change is an easy fix. I had to soak my old nozzle in isopropanol for quite some time to be able to remove the heater without force. The goop was probably harder than the press fit.

@froh42 I was being sincere - the video showing me take it apart and put it back together was as easy as I showed. Only did one take. Totally possible that they switched up the thermal compound between production of your machine and mine, tho, or that something about our different printing conditions impacted the goop. Sorry to hear it gave you such a hard time!

I did - it's around here somewhere. I'll see if I can dig it up. If so, I'll take some measurements and post them. Worst case, Sovol published a bunch of CAD models which should include the nozzle and hotend.

@@MaximalistWorkshop uh yeah thats a great idea, didn't think about that!

Thanks so much! That really means a lot.

right?! 🤣

Good eye - wasn't causing my issue, but that does seem to be the wrong fan port based on Sovol's official videos. I remember keeping everything the way it was from the factory, but it's possible I fumbled something at some point.

@MaximalistWorkshop no problem I have seen some other tubers make the same mistake its easy to do

Yep! You guessed it. I was using PETG at the time, and I think you're probably right. If that's the case, then things are going to get MUCH worse when the enclosures are finally shipped and people start trying to print with ABS, ASA, etc. I hate to speculate, but what if that's a reason the enclosures are taking so long?

@@MaximalistWorkshop supposedly they are working on a fix for this issue. The nozzle is from the Comgrow T300 so maybe they got a deal on a batch of those nozzles. I am planning use a proven Voron toolhead one mine, I don't want to deal with proprietary and poorly executed nozzles

​@@SKPhoto816 Thanks for the intel! Sounds like a true Voron toolhead is likely the way to go. I'll probably give some thought to doing the same once I've put the machine through its paces at stock. Maybe put a Chube on it or something.​

@@MaximalistWorkshop nice plan. I am researching the Xol toolhead. I need something that can do PLA and Engineering grade materials equally well

@@MaximalistWorkshop Well that's going to suck. I was hoping to use the sv08 as a dedicated ABS/ASA printer in my garage.

Interesting. I would still go with the Sovol, honestly, or at least something other than the TX. I'm only just hearing of the Infimech, and there's nothing about it that stands out as unique in terms of performance when compared to more common printers like the Bambu Lab X1C/P1S, the K1 series from Creality, Qidi's new machine, the 5M series from Flashforge, or the KLP1 from Kingroon. The leveling system is kinda cool, but it's not necessary, and those other machines machines all have parts readily available from both the manufacturer and third parties. As far as I can tell, they are all also from much more well-established companies. I plan to make a video on it at some point, but I've always been weary of printers from companies that don't have a mid-to-long track record ever since the Wizmaker P1 and some others died on arrival. At a glance, almost none of the parts being sold for the TX, even on the manufacturer's website, and something absolutely will break on a 3d printer. Even the nozzles aren't listed on their website, except as part of a complete hotend assembly. While Sovol is backed up with preorders, at least they dropped just about every part on their website on release, we get quick responses from Sovol for new parts (I don't have any experience with Infimech and can't compare), and we now have the CAD models for the SV08 to make upgrades or print our own parts.

@@MaximalistWorkshop Well I was surprised by this quite honest review kzfaq.info/get/bejne/gdBgfs2dtaupo2Q.html and This unknown brand is just a new sub-brand name of a rather big 3d printer company Flying Bears.. And although there is a reality K2 plus on the horizon, I , ve just had it with Creality in general, however You´re doing a great job here, and I still like the basic Idea of only moving the gantry (Sovol SV8), so perhaps the combination of this BIGTREETECH Eddy Auto Leveling Sensor and a Steathlburner Extruder Design would give a Sovol Sv8 its better extruder/leveling/ system.

Because the problem isn't that the z-offset is set wrong - the nozzle was actively being pushed out of the hotend during printing. No amount of pre-print calibration can account for this.

Thanks! I'm not one of the people who mentioned they have this issue, but I am on the Facebook pages for the SV08, so I've seen the posts you're talking about. Super useful to know this issue isn't happening for you with ABS and ASA! In that case, it's more likely that this is a PETG-specific issue, which is reassuring. Agreed that it would be nice for them to send out new nozzles to everyone so that we don't have to stare at our printers around the clock. If it's more feasible for them due to costs or low supply, I'd also be fine if they just sent the new ones to people with malfunctions, though, as long as they replace whatever else breaks. I just want this fixed soon.

@MaximalistWorkshop ill likely purchase a set of "fixed" nozzles when they are out. As far as watching my printer, lol I just don't. I feel comfortable enough with my machine that I can press go and walk away. I actually took one of my spare nozzles and heated it up with a soldering iron to well over 300°c and tried to pull the nozzle out with a couple of pliers. While I was able to get the nozzle to turn I could not pull it out, and ended up crushing the tip of the nozzle before it even showed signs of coming out. Good luck with your machine.

Including the Bambulab or is this just classic racism? You get what you pay for, if you want quality then pay more, broke ass.

They also have no morals about copying designs.

This is why I chose to build my own printer rather than buy a Bambu printer. Coming from prusa, the mk4 just felt lackluster and I wanted corexy. Never gonna give my money to Bambu

Hahahahaha - relatable! My Voron (located directly above my SV08) is still a jumble of wires from the last disassembly. I had actually been hoping to use the SV08 to repair it as sort of an homage.

unless... it's more worth it to get this cheap voron kit. But if you need another printer to fix this one. I can't buy it then. Because i'm trying to buy my first ever printer.

I would not recommend a Voron as your first printer, especially if you don't have the means to print new parts. It's not worth it, and the learning curve is much steeper than something already difficult like an Ender 3. I'm not sure why you don't like Bambu Lab, but they make great machines; I use one for any parts I actually care about in each of my workshops. They're reliable, and parts for them are both cheap and plentiful. Great for beginners.

@@MaximalistWorkshop @MaximalistWorkshop Yeah, you are right. The why I'm very interested in the sv08 because yes it's a voron and I have a thinkerer mindset. I love that i could tweak everything and nothing would stop me from modding every single bit of the machine. Sad thing that keeps me from buying it is those manufacturing weirdness. And the reason of why I 'hate/don't trust' BambuLab is because you can't own those machines. They connect to the internet without permission, you have to connect them if you want any convenience, also they upload telemetry. Also if something breaks it's very possible you can't fix it if there aren't parts available, you can't do board repair because we don't have the schematics. Closed Source everything, etc. That's why I'm having a hard time choosing what to buy :)

Possible! Tbh, automatic z offset on every printer except for Bambu Lab and Creality's X1/X1C are invariably slightly off. About as accurate as the paper method, in my view, but I think that's because Bambu and the X1 series rely primarily on a strain gauge instead of trying to use both a strain gauge and some other probe. Would need to do more testing to confirm.

@@MaximalistWorkshop a press fit that loose would be an excellent candidate for the greater part of the variability at least. In the end it's pointless though, they should have gone with a standard hotend, not this proprietary crap.

Thanks! That's a local IP address - they don't go anywhere except on a given local network. A public IP would be more of a concern. I think SomeOrdinaryGamers did a video on this at some point. Any time you see “192.168.x.x”, that’s not something that’s online and accessible except locally or through VPN or a similar tool.

I hear you. This nozzle has some issues, but Sovol makes good printers. The Ender 3 was iconic, and everybody sold (and continues to sell) some version of it, so Sovol isn't unique there.
