Of these options, I'd recommend the SV08, provided you are okay with some mods essentially being required for consistent, reliable use.
These being:
- Eddy sensor (for faster bed meshing, eddy-ng addon for Klipper adds auto z-offset)
- Mainline Klipper/Kalico (required for eddy functionality)
- Some motherboard fan replacement mod (the default is tiny, noisy, and always-on)
Of the others listed:
- Bambu printers and the Elegoo Centauri Carbon have locked-down firmware (possibly with hidden license violations).
- I think the only Prusa machine with that build volume is the XL, which is out of the price range
- The Creality Ender 3 V3 KE is okay, but the build volume is 220x220x240mm
This is if you like tinkering with printers. I gave away my Wanhao and bought a Bambu, and I haven't thought about the printer since. Now I just print.
These are upgrades, not tinkering. None of them are necessary, just QoL. The Eddy sensor is better than anything Bambu's "AI" cameras can do as far as leveling.
You can buy upgrades for your Bambu too.
Yes, but with Bambu I don't need to. Their 5x5 leveling works perfectly, though I will admit that eddy leveling is super cool. I bought a sensor but didn't use Kipper and couldn't use the sensor with Marlin, and I got a Bambu before I switched to Klipper, so I gave the sensor away.
