Jerk XY
Jerk is the rate of change of acceleration and how quickly your printer can change between different accelerations. It controls direction changes and velocity transitions during movement.
Cornering Control Types
- Jerk: Traditional method, sets a maximum speed for direction changes.
- Junction Deviation: Modern method, calculates cornering speed based on acceleration and speed.
Key Effects
- Corner Control: Lower values = smoother corners, better quality. Higher values = faster cornering, potential artifacts
- Print Speed: Higher jerk reduces deceleration at direction changes, increasing overall speed
- Surface Quality: Lower jerk minimizes vibrations and ringing, especially important for outer walls
This setting overrides firmware jerk values when different motion types need specific settings. Orca limits jerk to not exceed the Printer's Motion Ability settings.
Tip
Jerk can work in conjunction with Pressure Advance, Adaptive Pressure Advance, and Input Shaping to optimize print quality and speed. It's recommended to follow the calibration guide order for best results.
Default
Default Jerk value.
Note
If this value is set to 0, the jerk will be set to the printer's default jerk.
Outer wall
Jerk for outer wall printing. This is usually set to a lower value than normal printing to ensure better quality.
Inner wall
Jerk for inner wall printing. This is usually set to a higher but still reasonable value than outer wall printing to improve speed.
Infill
Jerk for infill printing. This is usually set to a value higher than inner wall printing to improve speed.
Top surface
Jerk for top surface printing. This is usually set to a lower value than infill to ensure better quality.
Initial layer
Jerk for initial layer printing. This is usually set to a lower value than top surface to improve adhesion.
Travel
Jerk for travel printing. This is usually set to a higher value than infill to reduce travel time.
Junction Deviation
Alternative to Jerk, 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.
This value will only be overwritten if it is lower than the Junction Deviation value set in Printer settings > Motion ability. If it is higher, the value configured in Motion ability will be used.
To Calculate your Junction Deviation value, please refer to the Junction Deviation Calibration guide.
JD = 0,4 \cdot \frac{\text{Jerk}^2}{\text{Accel.}}
