The SV08 is marketed as a mass-produced Voron 2.4, with a much lower price and a very quick setup. They even say they donate a small amount to the Voron project for each sale.

Has anyone here bought/tested it? What are your thoughts about it?

Are there some limitations/downsides compared to a Voron?

Is it possible to upgrade it Voron-style (Stealthburner, enclosure etc)?

Maybe.

I've built a Voron 2.4 350, and own an SV08. I'm currently working on a detailed teardown/analysis/reverse-engineering of the SV08.

From a user perspective, there haven't been any deal-breakers so far, but certainly some annoyances. In short:

  • The filament path between the extruder and hotend is poorly-constrained, making it a pain to load
  • The auto-z calibration is often just a smidge off
  • The fans are absurdly loud. All of them.
  • The camera is meh
  • It uses a custom nozzle/heater
  • The bed is a bit thin
  • The mainboard is effectively a BTT CB1 and Fystec Cheetah on a single board
  • Their software customizations are of dubious quality
  • Their OrcaSlicer profiles are... fine. Just fine.

That being said, there are also many nice touches and good attention to detail in other areas. Overall, I'm satisfied with my purchase, but don't buy it to upgrade (aside from the mainboard fan). There be dragons.

If a Voron 2.4 fits in your budget, get a Voron 2.4. if not, the SV08 is a good choice if you can live with those annoyances, and especially if you are comfortable with third-party firmware mods (whenever they come out).

As an aside: based on my analysis of the mainboard, I strongly suspect Sovol is working on an MMU for the SV08.

Than you so much for such a detailed analysis!

For reference, I've had a (heavily modded) Creality Ender 3 V2 for a few years, and I've hit a limit in terms of speed and quality.

The filament path between the extruder and hotend is poorly-constrained, making it a pain to load The auto-z calibration is often just a smidge off It uses a custom nozzle/heater

If it's possible to install a Stealthburner instead of the standard extruder/hotend combo, it might solve most of these issues. Maybe some people are working on a V6 or Mk8 style hotend (I have a metric fuckton of Mk8 nozzles laying around)...

The fans are absurdly loud. All of them.

OK Noctua upgrades then. Compared to an already absurdly loud Ender 3, is it worse?

The mainboard is effectively a BTT CB1 and Fystec Cheetah on a single board Their software customizations are of dubious quality

Would a Voron-style mainboard + RPi + standard Klipper solve these issues or are there fundamental incompatibilities?

Thanks!

All of those upgrades are absolutely doable. Given the price of those upgrades, all-in, a Voron will be a better value. Unless you have most of the parts already, anyway.

Although, I wouldn't bother changing out the board unless you have specific needs. Firmware and config tweaks will take care of most issues I've seen with it.

The fan is probably on par with stock ender 3. But always-on.
