Custom Profiles: Purge Wall

    The purge wall is an extraneous external structure that can be used to reduce mixing of materials during a dual extrusion print. 

    "doPurgeWall"

    True/false

    The purge wall is a feature designed to reduce traces of material left by the inactive extruder during a dual extrusion print. When "doPurgeWall" is set to "true," printed objects will include two printed walls that will catch any excess plastic hanging from the extruder nozzle so that the excess does not attach itself to the printed object. When "doPurgeWall" is set to "false," the purge walls will not be printed and the purge wall settings below will be ignored.

    "purgeWallModelOffset"

    Millimeters

    This setting determines the horizontal distance between the widest part of your print and the purge walls. The purge wall will always be at least this amount away from any given part of your print.

    "purgeWallXLength"

    Millimeters

    Each purge wall includes a section that runs along the X-axis and a section that runs along the Y-axis. The length of of the Y-axis section is determined by the length of your object on the Y-axis. The length of the X-axis section is equal to the number of millimeters set here.

    "purgeWallWidth"

    Millimeters

    This setting defines extrusion width on purge walls.

    "purgeWallBaseWidth"

    Millimeters

    Purge walls are supported by a base that resembles the base layer of a raft. "purgeWallBaseWidth" defines extrusion width on the base layer of purge walls.

    "purgeWallBasePatternLength"

    Millimeters

    Purge walls are supported by a base layer that resembles the base layer of a raft. "purgeWallBasePatternLength" defines the length of the pattern on the purge wall base layer.

    "purgeWallBasePatternWidth"

    Millimeters

    Purge walls are supported by a base layer that resembles the base layer of a raft. "purgeWallBasePatternWidth" defines the width of the pattern on the purge wall base layer. 

    "purgeWallBaseFilamentWidth"

    Millimeters

    This setting defines extrusion width on the base layer of the purge wall.

    "purgeWallPatternWidth" 

    Millimeters

    Layers of a purge wall are printed in an alternating zig-zag pattern. The alternating zig-zags create a diamond pattern. This setting determines the width of these diamonds.

    "purgeWallBucketSide"

    Millimeters

    Each end of a purge wall terminates in a square enclosure that will contain the loose ends of the walls. This setting determines the length of a side of the enclosure. 

    "purgeWallSpacing"

    Millimeters

    This setting defines the spacing between any adjacent purge walls. You may have adjacent purge walls if you are printing more than one dual material model at a time.
