# Flow rate
|

|

The Flow Ratio determines how much filament is extruded and plays a key role in achieving high-quality prints. A properly calibrated flow ratio ensures consistent layer adhesion and accurate dimensions.

# Flow Rate Calibration

- Too **low** flow ratio will cause under-extrusion, leading to gaps, weak layers, and poor structural integrity.
|
||||
- Too **high** flow ratio can cause over-extrusion, resulting in excess material, rough surfaces, and dimensional inaccuracies.

## Calibration Types
|
||||
|
||||
- **2-Pass Calibration:** Old method using two passes to determine the optimal flow rate using the formula `FlowRatio_old*(100 + modifier)/100`.
|
||||
- **YOLO:** Simplified method that adjusts the flow rate in a single pass using the formula `FlowRatio_old±modifier`.
|
||||
- **Recommended:** Calibration range `[-0.05, +0.05]`, flow rate step is `0.01`.
|
||||
- **Perfectionist Version:** Calibration range `[-0.04, +0.035]`, flow rate step is `0.005`.
|
||||
- **YOLO:** A simplified method that adjusts the flow rate in a single pass using the formula `OldFlowRatio ± modifier`.
|
||||
- **Recommended:** calibration range `[-0.05, +0.05]`, flow rate step `0.01`.
|
||||
- **Perfectionist:** calibration range `[-0.04, +0.035]`, flow rate step `0.005`.
|
||||
- **2-Pass Calibration:** the legacy method, using two passes to determine the optimal flow rate with the formula `OldFlowRatio * (100 + modifier) / 100`.
|
||||
|
||||
### OrcaSlicer > 2.3.0 Archimedean chords + YOLO (Recommended)
|
||||
|
||||
This example demonstrates the use of [Archimedean chords](strength_settings_infill#archimedean-chords) for flow rate calibration using the YOLO (Recommended) method.
|
||||
This method uses the [Archimedean Chords](strength_settings_patterns#archimedean-chords) pattern for flow rate calibration with the YOLO (Recommended) approach.
|
||||
|
||||
WIP...
|
||||
1. Select the printer and the filament you want to calibrate.
|
||||
This method is based on the filament's current flow ratio, so make sure you select the correct filament before proceeding.
|
||||
2. In the `Calibration` menu, under the `Flow Rate` section, select `YOLO (Recommended)`.
|
||||
3. A new project with eleven blocks will be created, each with a different flow rate modifier. Slice and print the project.
|
||||
|
||||
4. Examine the printed blocks and identify the one with the best surface quality. Look for:
|
||||
1. The smoothest top surface.
|
||||
2. No visible gaps between the pattern arcs.
|
||||
3. Minimal or no visible line between the Inner Spiral and the Outer Arcs.
|
||||
|
||||
In this example, the block with a flow modifier of `+0.01` produced the best results, despite a visible line between the Inner Spiral and the Outer Arcs; reducing the flow further begins to show gaps between the lines.
|
||||
|
||||
5. Update the flow ratio in the filament settings using the equation: `OldFlowRatio ± modifier`.
|
||||
If your previous flow ratio was `0.98` and you selected the block with a flow rate modifier of `+0.01`, the new value would be: `0.98 + 0.01 = 0.99`.
|
||||
**Remember** to save the filament profile.
|
||||
|
||||
|
||||
|
||||
> [!NOTE]
|
||||
> The new Archimedean chords pattern uses a specific print order that prints the inner spiral last so you can check for material accumulation on the contact line at the end.
|
||||
|
||||
### OrcaSlicer <= 2.3.0 Monotonic Line + 2-Pass Calibration
|
||||
|
||||
This example demonstrates the use of Monotonic Line for flow rate calibration using the 2-Pass Calibration method.
|
||||
This example uses the Monotonic Line pattern with the 2-Pass Calibration approach.
|
||||
|
||||
|
||||
|
||||
Calibrating the flow rate involves a two-step process.
|
||||
|
||||
1. Select the printer, filament, and process you would like to use for the test.
|
||||
2. Select `Pass 1` in the `Calibration` menu
|
||||
3. A new project consisting of nine blocks will be created, each with a different flow rate modifier. Slice and print the project.
|
||||
1. Select the printer, filament, and process you want to use for the test.
|
||||
2. In the `Calibration` menu, under the `Flow Rate` section, select `Pass 1`.
|
||||
3. A new project with nine blocks will be created, each with a different flow rate modifier. Slice and print the project.
|
||||
4. Examine the blocks and determine which one has the smoothest top surface.
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
5. Update the flow ratio in the filament settings using the following equation: `FlowRatio_old*(100 + modifier)/100`. If your previous flow ratio was `0.98` and you selected the block with a flow rate modifier of `+5`, the new value should be calculated as follows: `0.98x(100+5)/100 = 1.029`. **Remember** to save the filament profile.
|
||||
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.
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
5. Update the flow ratio in the filament settings using the equation: `OldFlowRatio * (100 + modifier) / 100`.
|
||||
For example, if your previous flow ratio was `0.98` and you selected the block with a flow rate modifier of `+5`, the new value would be: `0.98 × (100 + 5) / 100 = 1.029`.
|
||||
**Remember** to save the filament profile.
|
||||
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. For example, if your previous flow ratio was `1.029` and you selected the block with a flow rate modifier of `-6`, the new value would be: `1.029 × (100 - 6) / 100 = 0.96726`.
|
||||
**Remember** to save the filament profile.
