I just set up my CR6 SE and have used both Cura 4.8 and the Creality Slicer with Spiralize Outer Contour (Vase Mode) and it fails every time.
My 8 bit Anycubic i3 Mega printer has no issue at all. Pumps my print out flawlessly in no time.
This is not a GCode read error or 8 bit vs 32 bit. Either there is a flaw in the Creality's Mariln version or there is a hardware design problem.
CREALITY.. YOU NEED TO FIX THIS ASAP.
