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. If the flow ratio is too low, under-extrusion may occur, leading to gaps, weak layers, and poor structural integrity. On the other hand, a flow ratio that is too high can cause over-extrusion, resulting in excess material, rough surfaces, and dimensional inaccuracies.
Warning
For Bambulab X1/X1C users, make sure you do not select the 'Flow calibration' option.
Important
PASS 1 and PASS 2 follow the older flow ratio formula
FlowRatio_old*(100 + modifier)/100
. YOLO (Recommended) and YOLO (perfectist version) use a new system that is very simpleFlowRatio_old±modifier
.
Calibrating the flow rate involves a two-step process.
-
Select the printer, filament, and process you would like to use for the test.
-
Select
Pass 1
in theCalibration
menu -
A new project consisting of nine blocks will be created, each with a different flow rate modifier. Slice and print the project.
-
Examine the blocks and determine which one has the smoothest top surface.
-
Update the flow ratio in the filament settings using the following equation:
FlowRatio_old*(100 + modifier)/100
. If your previous flow ratio was0.98
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. -
Perform the
Pass 2
calibration. This process is similar toPass 1
, but a new project with ten blocks will be generated. The flow rate modifiers for this project will range from-9 to 0
. -
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.
Tip
@ItsDeidara has made a html to help with the calculation. Check it out if those equations give you a headache here.
