# Cornering
|
||||
|
||||
Cornering is a critical aspect of 3D printing that affects the quality and accuracy of prints. It refers to how the printer handles changes in direction during movement, particularly at corners and curves. Proper cornering settings can help reduce artifacts like ringing, ghosting, and overshooting, leading to cleaner and more precise prints.

## Junction Deviation
|
||||
|
||||
Junction Deviation is the default method for controlling cornering speed in MarlinFW (Marlin2) printers.
|
||||
Higher values result in more aggressive cornering speeds, while lower values produce smoother, more controlled cornering.
|
||||
The default value in Marlin is typically set to 0.08mm, which may be too high for some printers, potentially causing ringing. Consider lowering this value to reduce ringing, but avoid setting it too low, as this could lead to excessively slow cornering speeds.

||||
Junction Deviation is the default method for controlling cornering speed in **Marlin firmware (Marlin 2.x)**.
|
||||
Higher values allow more aggressive cornering, while lower values produce smoother, more controlled corners.
|
||||
The default value in Marlin is often `0.08mm`, which may be too high for some printers and may cause ringing. Consider lowering this value to reduce ringing, but avoid setting it too low that could lead to excessively slow cornering speed.

JD = 0,4 \cdot \frac{\text{Jerk}^2}{\text{Accel.}}

1. Pre-requisites:
|
||||
1. Check if your printer has Junction Deviation enabled. You can do this by sending the command `M503` to your printer and looking for the line `Junction deviation: 0.25`.

1. Check if your printer has Junction Deviation enabled. Look for `Junction deviation` in the printer's advanced settings.
|
||||
2. 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. Use an opaque, high-gloss filament to make the ringing more visible.

2. It’s very likely that you’ll need to set values lower than 0.08 mm, as shown in the previous example. To determine a more accurate maximum JD value, you can print a new calibration tower with a maximum value set at the point where the corners start losing sharpness.
