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.
