Acceleration

Acceleration in 3D printing is usually set on the printer's firmware settings.
This setting will try to override the acceleration when normal printing acceleration value is different than 0.
Orca will limit the acceleration to not exceed the acceleration set in the Printer's Motion Ability settings.

• Normal printing
• Outer wall
• Inner wall
• Bridge
• Sparse infill
• Internal solid infill
• Initial layer
• Top surface
• Travel

Normal printing

Variable: default_acceleration.
The default acceleration of both normal printing and travel.

Note

If this value is set to 0, the acceleration will be set to the printer's default acceleration.

Outer wall

Variable: outer_wall_acceleration.
Acceleration for outer wall printing. This is usually set to a lower value than normal printing to ensure better quality.

Inner wall

Variable: inner_wall_acceleration.
Acceleration for inner wall printing. This is usually set to a higher value than outer wall printing to improve speed.

Bridge

Variable: bridge_acceleration.
Acceleration of bridges. If the value is expressed as a percentage (e.g. 50%), it will be calculated based on the outer wall acceleration.

Sparse infill

Variable: sparse_infill_acceleration.
Acceleration of sparse infill. If the value is expressed as a percentage (e.g. 100%), it will be calculated based on the default acceleration.

Internal solid infill

Variable: internal_solid_infill_acceleration.
Acceleration of internal solid infill. If the value is expressed as a percentage (e.g. 100%), it will be calculated based on the default acceleration.

Initial layer

Variable: initial_layer_acceleration.
Acceleration of initial layer. Using a lower value can improve build plate adhesion.

Top surface

Variable: top_surface_acceleration.
Acceleration of top surface infill. Using a lower value may improve top surface quality.
Recommended to use a similar value to the outer wall acceleration.

Travel

Variable: travel_acceleration.
Acceleration of travel moves. This is usually set to a higher value than normal printing to reduce travel time.
