This test data is for printing the first layer only. Used to determine good or bad adhesion to the build plate. It is considered difficult to make this adhesiveness strictly uniform due to factors such as the flatness of the table and the temperature distribution of the heatbed. However, by knowing the current trends, it will be the basis for considering the temperature and fan settings for the printing conditions you are going to try. Print size (W x D x H mm): 219 x 219 x 0.1 Note: A gcode file (slice result) when using Creality Hyper PLA as a material can be found at: https://file2-cdn.creality.com/model/021891c59c21b421952cc0c8fc7b4f19.gcode
