Cornering
Tests how the printer handles rapid direction changes. This is primarily a printer-motion adjustment, not a basic filament setting.

Calibration Tests in Menu Order
This lesson follows the calibration menu shown in Snapmaker Orca 2.3.5. Complete the five filament-related tests first, in order, before considering the advanced printer-motion tests.
Filament Calibration
Complete these five tests in order
| Order | Snapmaker Orca test | Question it answers | A good result |
|---|---|---|---|
| 1 | Temperature | How hot should the nozzle be for this filament? | Strong layer adhesion, clean surfaces, controlled bridging, and minimal stringing. |
| 2 | Flow Rate (Flow Ratio) | Is the printer extruding too much or too little filament? | Smooth surfaces and lines without gaps or excess filament. |
| 3 | Pressure Advance | How should extrusion respond when the toolhead changes speed or direction? | Consistent line width and clean corners without bulges or gaps. |
| 4 | Retraction Test | How much filament should be pulled back during a travel move? | The shortest reliable retraction that controls stringing without creating gaps. |
| 5 | Max Flowrate (Maximum Volumetric Speed) | How quickly can the hotend melt and extrude this filament reliably? | The highest tested flow rate that still preserves surface quality and extrusion. |
Snapmaker Orca 2.3.5 orderTemperature → Flow Rate → Pressure Advance → Retraction Test → Max Flowrate. Each later test depends on the earlier filament settings being reasonable.

Continue only when the basic filament profile is working
Input Shaping
Compensates for mechanical vibration that can create ringing or ghosting around sharp features.
VFA
Tests for repeating vertical surface artifacts that can appear at particular movement speeds.
Tutorial is not a testThe Tutorial entry at the bottom of the Snapmaker Orca Calibration menu opens instructional help; it is not another calibration step.
When to run U1 Dynamic Flow CalibrationThe U1’s automatic Dynamic Flow Calibration runs from the printer’s print-start options and is separate from the manual Flow Rate and Pressure Advance tests in this slicer menu. Run Dynamic Flow Calibration after changing the filament loaded in a toolhead. If the same filament remains loaded and its setup has not changed, the calibration generally does not need to be repeated for every print.
