Used this model to test my printer's capabilities. Printed them with 0.4mm nozzle, but with different layer height, speed and settings. Mostly, tried to push my printer to the maximum. However, it turned out that the limitation might not happening by the printer, but the filament. (layer addhession issues, flowing uncontrollably on corner, etc...) I figured out that Creality Value Pack PLA is not tolerate speed up to 80mm/sec. Does not matter how much I'm trying. Other PLAs having no issues with that speed. However, it was good to figure out the best jerk settings and other parameters within my printer firmware to set.
