I’m unfortunately not here to offer much help, but just to let you know I have the exact same issue. See these pictures below from my flow rate calibrations.
I’m having what I think is a related issue with nozzle bulldozing, leading to buildup, leading to shedding clumps onto my build plate, leading to failed prints. (see here)
At this point, I’m guessing this is a bug somehow present in the K2’s firmware or in CP, although I (obviously) haven’t figured out the mechanism/exact issue. If you make any progress, I’d be interested to hear what you find!
