## Z distance

[Mode](option_mode): `Advanced`.  
[Variables](built_in_placeholders_variables): `support_top_z_distance`, `support_bottom_z_distance`.  
The Z gap between support interface and object.

## Support wall loops

[Mode](option_mode): `Advanced`.  
[Variable](built_in_placeholders_variables): `tree_support_wall_count`.  
This setting specifies the count of support walls in the range of [0,2]. 0 means auto.

## Base Pattern

[Mode](option_mode): `Advanced`.  
[Variable](built_in_placeholders_variables): `support_base_pattern`.  
Line pattern for the base of the support.

### Base pattern spacing

[Mode](option_mode): `Advanced`.  
[Variable](built_in_placeholders_variables): `support_base_pattern_spacing`.  
Spacing between support lines.

## Pattern angle

[Mode](option_mode): `Advanced`.  
[Variable](built_in_placeholders_variables): `support_angle`.  
Use this setting to rotate the support pattern on the horizontal plane.

## Interface layers

[Mode](option_mode): `Advanced`.  
[Variables](built_in_placeholders_variables): `support_interface_top_layers`, `support_interface_bottom_layers`.  
The number of interface layers.

## Interface pattern

[Mode](option_mode): `Advanced`.  
[Variable](built_in_placeholders_variables): `support_interface_pattern`.  
The pattern used for the support interface.

## Interface spacing

[Mode](option_mode): `Advanced`.  
[Variables](built_in_placeholders_variables): `support_interface_spacing`, `support_bottom_interface_spacing`.  
Spacing of interface lines. Zero means solid interface.

## Normal support expansion

[Mode](option_mode): `Advanced`.  
[Variable](built_in_placeholders_variables): `support_expansion`.  
Expand (+) or shrink (-) the horizontal span of normal support.

## Support/object XY distance

[Mode](option_mode): `Advanced`.  
[Variable](built_in_placeholders_variables): `support_object_xy_distance`.  
XY separation between an object and its support.

## Support/object first layer gap

[Mode](option_mode): `Advanced`.  
[Variable](built_in_placeholders_variables): `support_object_first_layer_gap`.  
XY separation between an object and its support at the first layer.

## Don't support bridges

[Mode](option_mode): `Advanced`.  
[Variable](built_in_placeholders_variables): `bridge_no_support`.  
Don't support the whole bridge area which make support very large. Bridges can usually be printed directly without support if not very long.

## Independent support layer height

[Mode](option_mode): `Advanced`.  
[Variable](built_in_placeholders_variables): `independent_support_layer_height`.  
Support layer uses layer height independent with object layer. This is to support customizing z-gap and save print time. This option will be invalid when the prime tower is enabled.
