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?
