Extruder Clearance

Extruder clearance settings define the minimum distances required around the extruder to avoid collisions with the print bed, rods, or lid during printing. These settings are particularly important for printers with complex geometries or when using by-object printing modes.

Radius

Mode: Advanced.
Variable: extruder_clearance_radius.
Type: Float.
CLI Example: --extruder-clearance-radius=1.
Clearance radius around extruder: used for collision avoidance in by-object printing.

Distance to rod

Mode: Advanced.
Variable: extruder_clearance_dist_to_rod.
Type: Float.
CLI Example: --extruder-clearance-dist-to-rod=1.

Horizontal distance from the nozzle tip to the rod's farther edge. Besides by-object printing, it sizes the keep-out band the gantry rod sweeps around a prime tower printed with no sparse layers.

Height to rod

Mode: Advanced.
Variable: extruder_clearance_height_to_rod.
Type: Float.
CLI Example: --extruder-clearance-height-to-rod=1.
Distance from the nozzle tip to the lower rod. Used for collision avoidance in by-object printing.

Height to lid

Mode: Advanced.
Variable: extruder_clearance_height_to_lid.
Type: Float.
CLI Example: --extruder-clearance-height-to-lid=1.
Distance from the nozzle tip to the lid. Used for collision avoidance in by-object printing.
