Hello!
I just build my model K8200 finished.
Everything is calibrated as described.
But when I try to print then Z axis does not rise fast enough.
It prints just at the previous layer.
But when I test manually it rises the 10mm as I choose.
The extrusion rate (multiplier in slicer) is set in this window:
Here it is set to 115%
I suggest to set the multiplier to 1.0 and then adjust the flow rate (repetier manual control tab)
during printing to find the best value.
