 - Points and bounding boxes are stored as `[x, y]` pairs expressed in mm.
 - `layer_num` is one-based (first layer is `1`). All other indices use zero-based numbering.

 2. Take note of the optimal PA value for each volumetric flow speed and acceleration. You can find the flow number by selecting "flow" from the color scheme drop down and move the horizontal slider over the PA pattern lines. The number should be visible at the bottom of the page. The ideal PA value should be decreasing the higher the volumetric flow is. If it is not, confirm that your extruder is functioning correctly. The slower and with less acceleration you print, the larger the range of acceptable PA values. If no difference is visible, use the PA value from the faster test.
 3. Enter the triplets of PA values, Flow and Accelerations in the text box here and save your filament profile.
