Hi.
As title.
I print mainly using PETG and having read of issues with nozzles, I’m worried that the 2 nozzles supplied with my new SV08 are the same type that have the issues. I’ll attach some pics if I can and hope someone can advise.
If indeed the nozzles I have are not suitable for PETG, how would I go about getting replacements?
Many Thanks.

I don’t have an SV08, but I haven’t read about any issues with PETG.
The Stainless Steel nozzle should be fine for PETG, PLA & TPU…just like any other printer that uses Brass nozzles.
If you want to print Glow In The Dark or some Carbon Fiber, then you would need a Hardened nozzle…and increase the hotend temp 5*-10* hotter.
Hi Lion.
There are many documented reports of the original nozzles failling while printing PETG,
The nozzle tip which is pressed into the main body seems to move under pressure and gets lower than it should and can also completely detach, oftern resulting in build plate damage.
Sovol have redesigned the nozzles and the new range are available now.
I waited a few months to order this printer because of the reported nozzle issues and I really need it to print PETG. As the new revised nozzles are out there, I thought now might be a good time to buy.
I guess I need new nozzles. I have already contacted Sovol support via email.

I am printing a lot in PETG too and i had the issue. I do not understood all but you can just make a hole on your nozzle and add a small piece of metal to make it stronger. It’s explained here and existing some model (on printable if i am well remember) to have a template where to do the hole : Mayor crash after many flawless prints - #8 by wrusman
In addition, i recommand you to reduice the flow (parameter named Maximum Volumetric Speed on your filement) to something like 10mm3/s instead of default value provided by Sovol for orca. That should avoid the trouble + the quality of your print will be very better (at least that worked for me).
PS: And if you experiment the trouble, Sovol is very reactive and send the new nozzle + bed plate quickly… but it’s always better to do not need replacement.
PS2: I found the template Template to drill Hole in SV08 Heatblock/Nozzle by cascadier - Thingiverse

Good info to know, I had no idea that this was an issue.
I understand that Sovol has solved the problem by producing a new nozzle model.
Maybe it’s safer to use it.
If you take a look at the other side of the spare nozzle, there should be a set screw above the thermistor hole. You can also check this on the mounted hotend when you remove the spring clip that holds the heater element
Also be aware that these are not stainless or hardened nozzles, just brass with a shiny coating as far as I know.
Thanks all for the info.
I tried some prints using PETG earlier today. Everything looked fine for an hour or so till the nozzle started dragging on the print.
I checked everything and the result was the nozzle has moved about 0.5mm lower in the hotend.
Luckily I cought it before things got bad, all I lost was some PETG and a little time.
I unloaded the PETG and loaded in some PLA, set the Z offset and printed a few test prints which all completed fine and the nozzle did not drop any lower.
So now I know new nozzles are required for printing PETG, I confirmed that both nozzles I have do not have a grub screw.
Until you get the fixed nozzles, you could try mounting an undamaged nozzle and adjust the incorrect/crazy high volumetric flow that Sovol has in its default profile. 17mm^3/s is crazy high, try 10 tops.
That should lessen the pressure buildup inside the nozzle. But it is still a bad nozzle design. There is a reason that lot of nozzle adapters have sprung up: Mount Bambu Lab clone hotends, MicroSwiss releasing their FlowTech hotswappable nozzles for SV08 etc.

Hi all.
After I discovered the nozzle was working it way lower in the hot end, I stopped printing PETG.
I contacted sovol support and after a few days I was notified by them that as I had purchased the SV08 from Amazon, that I should contact a different sovol support which I did.
A couple of days later they contacted me and confirmed that They will supply 2 new nozzles that are safe to print PETG.
The little printing that I have done so far has produced pretty good results, it’s just a shame that the user experience has suffered due to the nozzle issues.
I appreciate the advice offered here but I refuse to accept that settings should be altered or hot ends should be modified to to allow the printer to perform within its claimed ability.
I waited weeks after the new nozzles were made available to purchase the printer in the hope that it would not suffer these issues.
Let’s hope the new nozzles arrive soon.
I completely agree, that’s why I have contacted Sovol after the crash I had and they promptly provided all the replacement parts needed to get the printer in a “out of the box” condition.
So hats off to Sovol support!
The modifications to the nozzles are made just so I could get printing again and to prevent a second sv08 I purchased for my makerspace from developing the same issues.

Yes! hats off to Sovol support.
I appreciate the fast resolution of the issue.
The 2 new nozzles arrived today and although I havent fitted them, they look good.
I had also ordered 2PCS 0.4mm Hardened Steel Nozzle Kit For SV08/T300 from Ali Express about 1 week ago and they were delivered at the same time.
Thank you Sovol.
Try “ePLA” print like PLA but said to be stronger and cope with higher temperatures than PETG
