 Calibrating the flow rate involves a two-step process.  
 Steps
 1. Select the printer, filament, and process you would like to use for the test.

 6. Perform the `Pass 2` calibration. This process is similar to `Pass 1`, but a new project with ten blocks will be generated. The flow rate modifiers for this project will range from `-9 to 0`.
 7. Repeat steps 4 and 5. In this case, if your previous flow ratio was 1.029 and you selected the block with a flow rate modifier of -6, the new value should be calculated as follows: `1.029x(100-6)/100 = 0.96726`. ** Remember ** to save the filament profile.
