A simple PLA heat tower that prints in vase mode. Every 10 millimeters the temperature changes by 5°C. It starts at 240°C and ends at 190°C. Only one bottom layer is printed to determine the quality of the first layer. To preset the temperatures, you must manually enter your own G-code (M109 S240, M109 S 235..... M109 S190) with a pause to equalize the desired temperature, or (M104 S240, M104 S 235..... M104 S190) for smooth print as shown in the photo. When uploading the 3MF file, a warning popped up saying that the G-code changes would not be included.
