• Call: import fullseye as fs; fs.ledger.contours_to_gcode(contours: 'Any', z: 'float', layer: 'int' = 0, layer_mm: 'float' = 0.2, line_width_mm: 'float' = 0.4, filament_mm: 'float' = 1.75, feed_mm_min: 'float' = 1800.0) -> 'dict[str, np.ndarray]' (to call the implementation directly, import printpath; printpath.contours_to_gcode(contours: 'Any', z: 'float', layer: 'int' = 0, layer_mm: 'float' = 0.2, line_width_mm: 'float' = 0.4, filament_mm: 'float' = 1.75, feed_mm_min: 'float' = 1800.0) -> 'dict[str, np.ndarray]'; from the registry, opsprintpath.get("contours_to_gcode"))
Turns contours (the table of mesh_slice_contours) into a table of paths that trace around them (same columns as gcode_read).
A minimal slicer: each ring is traced once in turn, and the extrusion amount is segment length × line width × layer height / filament cross-section area. Between rings there is travel (e = 0). A tool for making synthetic G-code with ground truth; it has no infill or retraction.
