Pushing the modified Creality K1 CoreXY 3D Printer higher! (800MM/S AT 40000 ACCELERATION REACHED) 

Hey everyone!
Today, I'm testing my Creality K1, with a modified side fan duct, filament dryer, rooted system (Mainsail/Moonraker), Micro Swiss Flowtech Hotend, new version of Creality's K1 extruder, textured PEI build plate, and a different toolhead cover with a better cooling duct design.
This video shows the machine reaching higher over its advertised limit, because of its software modification mostly. Manually controlled on the Mainsail tab I have on my computer.
This video also proves that you do not need to modify your belts, pulleys, or motors to reach these speeds on the already-installed speed test file on the Creality K1/K1 Max/K1C.
Happy printing!
