We need to hold a conversation on print speeds. My rigs can print fast. My extruders can move a lot of filament fast, ..... Until we begin to go bigger on the nozzle sizes and layer heights. And now we are pushing a lot more filament at a given speed. And I have to slow my rigs down so they can lay down all that filament. I am going after a mosquito magnum for my next hotend and I will see how much that helps. But we should post up nozzle size and layer heights when discussing print speed just like we should post up acceleration and jerk/junction deviation settings when bragging on print speeds. With thick layers and large diameter nozzles the filament moves so fast through the extruder it just doesn't have time to melt.
