about

nx_gcode_emit.nx -- compose every P0-P2 primitive into actual Klipper-flavour G-code text. This is the closing-the-loop primitive: NxSliceContours + NxMachineGraph + NxMaterialProfile + nx_gcode_extrude + nx_q14_format -> .gcode file bytes that Klipper/Moonraker can execute. Per cardinal NISHI_3D_PRINT_ROADMAP §2.5: every emitted G-code file carries its provenance manifest as a comment-line header (composes nx_gcode_manifest). G-code comments are universally ignored by firmware -- zero behaviour impact, clean EXCEED axis vs every SOTA slicer (none of which embed source provenance). G-code structure emitted (subset for v1; richer post-processing queued): ; <manifest header lines if caller supplies one> M104 S<print_temp> ; hotend target (no wait) M140 S<bed_temp> ; bed target (no wait) M190 S<bed_first_layer> ; wait bed M109 S<hotend_first> ; wait hotend G28 ; home all G92 E0 ; reset extruder G1 Z<safe_z> F300 ; --- per layer --- ;LAYER:<n> M106 S<fan_pct> ; fan (post first-layer) ; --- per polygon --- G0 X<x> Y<y> Z<z> F<travel> G1 X<x> Y<y> E<acc> F<print> ; --- end --- M104 S0 M140 S0 G1 Z<top> M84 Coordinate convention: Q14 fixed-point inputs throughout, emitted as decimal text via nx_q14_to_decimal (3 fractional digits ->
