¶ Introduction
¶ What is Maximum volumetric speed Calibration?
- Different filaments have varying maximum volumetric speeds.
- Factors such as nozzle material, diameter, and printing temperature all influence the maximum volumetric speed.
- Setting the maximum volumetric speed too high, especially if it doesn't match the filament characteristics, can result in missing lines during printing, leading to a degraded surface texture on the model.
The Maximum Volumetric Speed Calibration is a test designed to help calibrate the maximum volumetric speed for a specific filament. This test is especially useful when third-party filaments are used, and the correct volumetric speed hasn’t been set in the filament settings.
¶ When is the Maximum volumetric speed calibration performed?
The software has preset appropriate values for the official filaments. However, calibration may be necessary in the following situations:
- No filament is configured by default (e.g., when using third-party filaments).
- The nozzle material or diameter has been changed, or the default printing temperature has been modified.
- Missing lines, insufficient extrusion, or broken fills are observed during the printing process.
¶ Procedure
-
Select Calibration--Maximum volumetric speed, In the pop-up window, enter Start volumetric speed, End volumetric speed, Volumetric speed step. Click the OK button.
-
The software will automatically generate the model, simply slice the model and print it out. Print results are as follows.
It can be observed that at a certain height, the model begins to show missing sections. There are two ways to measure the maximum volumetric speed:
-
Observe the number of notches (nums) on the right and bring them into the following formula:
Max Volumetric Speed = StartV + (step * 2) * nums. -
On the Preview page, view the GCode of the model and find the flow value corresponding to the missing part.
- Save the resulting values.
