During high-speed movements, vibrations can cause a phenomenon called "ringing," where periodic ripples appear on the print surface. Input Shaping provides an effective solution by counteracting these vibrations, improving print quality and reducing wear on components without needing to significantly lower print speeds.

||||

||||
### ZV Input Shaping

### Resonance Compensation
|
||||
|
||||
The Klipper Resonance Compensation is a set of Input Shaping modes that can be used to reduce ringing and improve print quality.
|
||||
Ussualy the recommended values modes are ``MZV`` or ``EI`` for Delta printers.
|
||||
|
||||
1. Pre-requisites:
|
||||
1. In OrcaSlicer, set:
|
||||
1. Acceleration high enough to trigger ringing (e.g., 2000 mm/s²).
|
||||
2. Speed high enough to trigger ringing (e.g., 100 mm/s).
|
||||
3. Jerk [Klipper Square Corner Velocity](https://www.klipper3d.org/Kinematics.html?h=square+corner+velocity#look-ahead) to 5 or a high value (e.g., 20).
|
||||
2. In printer settigs:
|
||||
1. Set the Shaper Type to ``MZV`` or ``EI``.
|
||||
```
|
||||
SET_INPUT_SHAPER SHAPER_TYPE=MZV
|
||||
```
|
||||
2. Disable [Minimun Cruise Ratio](https://www.klipper3d.org/Kinematics.html#minimum-cruise-ratio) with:
|
||||
```
|
||||
SET_VELOCITY_LIMIT MINIMUM_CRUISE_RATIO=0
|
||||
```
|
||||
3. Use a high gloss filament to make the ringing more visible.
|
||||
2. Print the Input Shaping Frequency test with a range of frequencies.
|
||||
1. Measure the X and Y heights and read the frequency set at that point in Orca Slicer.
|
||||
2. If not a clear result, you can measure a X and Y min and max acceptable heights and repeat the test with that min and max value.
|
||||
|
||||
**Note**: There is a chance you will need to set higher than 60Hz frequencies. Some printers with very rigid frames and excellent mechanics may exhibit frequencies exceeding 100Hz.
|
||||
3. Print the Damping test setting your X and Y frequency to the value you found in the previous step.
|
||||
1. Measure the X and Y heights and read the damping set at that point in Orca Slicer.
|
||||
**Note**: Not all Resonance Compensation modes support damping

#### ZV Input Shaping
|
||||
|
||||
ZV Input Shaping introduces an anti-vibration signal into the stepper motion for the X and Y axes. It works by splitting the step count into two halves: the first at half the frequency and the second as an "echo," delayed by half the ringing interval. This simple approach effectively reduces vibrations, improving print quality and allowing for higher speeds.

Junction Deviation is the default method for controlling cornering speed in MarlinFW printers.

Higher values result in more aggressive cornering speeds, while lower values produce smoother, more controlled cornering.
