  - (Normal mode) If more than 1 temperature step is defined, the tool will print with a separate temperature in every column
  - (Fill mode) If only one temperature is defined, the columns will be filled with the flow increments. This is especially handy with printheads that need a lot of clearance (e.g. Prusa Mk3)
