Calibration Guide
This guide offers a structured and comprehensive overview of the calibration process for OrcaSlicer.
It covers key aspects such as flow rate, pressure advance, temperature towers, retraction tests, and advanced calibration techniques. Each section includes step-by-step instructions and visuals to help you better understand and carry out each calibration effectively.
To access the calibration features, you can find them in the Calibration section of the OrcaSlicer interface.
Important
After completing the calibration process, remember to create a new project in order to exit the calibration mode.
The recommended order for calibration is as follows:
-
Temperature: Start by calibrating the temperature of the nozzle and the bed. This is crucial as it affects the viscosity of the filament, which in turn influences how well it flows through the nozzle and adheres to the print bed.
-
Max Volumetric Speed: Calibrate the maximum volumetric speed of the filament. This is important for ensuring that the printer can handle the flow rate of the filament without causing issues like under-extrusion.
-
Pressure Advance: Calibrate the pressure advance settings to improve print quality and reduce artifacts caused by pressure fluctuations in the nozzle.
-
Adaptive Pressure Advance: This is an advanced calibration technique that can be used to further optimize the pressure advance settings for different print speeds and geometries.
-
-
Flow: Calibrate the flow rate to ensure that the correct amount of filament is being extruded. This is important for achieving accurate dimensions and good layer adhesion.
-
Retraction: Calibrate the retraction settings to minimize stringing and improve print quality. Doing this after Flow and Pressure Advance calibration is recommended, as it ensures that the printer is already set up for optimal extrusion.
-
Cornering: Calibrate the Jerk/Junction Deviation settings to improve print quality and reduce artifacts caused by sharp corners and changes in direction.
-
Input Shaping: This is an advanced calibration technique that can be used to reduce ringing and improve print quality by compensating for mechanical vibrations in the printer.
-
VFA: A VFA speed test is available to find resonance speeds.
Tolerance: Calibrate the tolerances of your printer to ensure that it can accurately reproduce the dimensions of the model being printed. This is important for achieving a good fit between parts and for ensuring that the final print meets the desired specifications.
