about

nx_contour_print.nx -- LIB: the UNIFIED multi-material contour emitter (3D-printing R1b). Generalises from a hardcoded rectangle to ANY closed polygon contour, so arbitrary geometry (not just a wall) prints in any material through ONE function. (Production contours come from the mature nx_slice_* pipeline; this proves the emitter accepts arbitrary polygons + makes the R-ECO cistern ROUND.) Material family selects the deltas: FILAMENT = hot hotend (M104/M109), METAL = arc (M3/M5) + inter-layer cooling dwell (G4), PASTE = cold; the contour-tracing + layering is shared. No float: a 12-point integer circle table + Newton integer sqrt for path length. CARDINAL 26: motion + extrusion/arc/hotend-temp only; no firmware/EEPROM. license_tier: ORIGINAL
