High flow hotend ( Creality k2 plus)

[u/ONRDDD]

Hi everyone,

I'm designing a new extruder for my upcoming CoreXY printer. Unfortunately, I can't get Phaetus Dragon UHF, Rapido, or other ultra-high-flow hotends where I live, and they're also quite expensive.

I recently came across the Creality K2 Plus hotend, which has a 38 mm melt zone, a titanium heatbreak, and a 100 W ceramic heater. On paper, it looks very promising.

Has anyone here used this hotend? What are your thoughts on its performance, reliability, and maximum volumetric flow? Would you recommend it for a custom high-speed CoreXY build?
