Minimal Layer Time:

• Definition: Desired minimum amount of time taken to print each single layer specified in metric hours. If printing layer time is lower than parameter value, printer will initiate a delay to reach the expected minimum layer time.

Support Angle:

• Definition: The overhang angle threshold to start placing support. When 0, “model to print surface” (i.e. build plate) support is disabled. If greater than 0, “model to print surface” support is enabled.

Support Line Distance:

Support X/Y Distance:

• Definition: The standoff distance between the support features and the outermost wall (exterior) of the print, specified in inches.

Support Z Distance:

• Definition: The gapped vertical spacing between support and the model’s solid outline. Increase to lower the adhesion of supports to the model, making them easier to remove.

Prime Amount:

• Definition: Length of forward extrusion following a retraction, before resuming printing moves within the model.

Minimal Travel Before Retraction:

• Definition: The extent of a non-printing travel move, by the printhead, that determines whether retraction is implemented before travelling. For example, if set to 2 mm, features that are only 0.5 mm apart will not cause retraction/prime to be added.

Minimal Extrusion Before Retraction:

• Definition: Minimal input material the extruder shall have deposited before implementing retraction for a particular travel move.

Retraction Z Hop:

• Definition: Provides an extruder head vertical lift to assist the effectiveness of extruder retraction and avoid extra time in contact with the printed model.
