Stealthburner ended up fixing your clog issues entirely?
More or less. You can check my post history, made a lot of fuss about it here trying to get it squared away, in part it was caused by some magically reoccurring issue where my printer boards were reporting incorrect hotend temps (sometimes off by as much as 70°C). But even after fixing that side of things my old setup kept clogging; kept diagnosing back and forth between extruder and hotend, decided why not build a stealthburner and replace both, if that doesn't fix the problem then I'm part way done with building a voron.
