nx_fdm_gcode.nx

nx_fdm_gcode.nx -- LIB: a standard-FILAMENT (FDM) wall emitter -- the filament arm of the multi-material dispatcher, parallel to nx_paste_gcode (concrete) + nx_metal_gcode (metal), so the SAME wall primitive can be emitted in any material. (Production filament uses the mature nx_slice_*->nx_gcode_emit pipeline for arbitrary geometry; this is the wall primitive for the multi-material demo.) The FDM signature vs concrete/ metal: a HOT hotend (M104/M109) + sub-millimetre layers (decimal Z). Reads the material profile (temp + layer height). CARDINAL 26 (never-brick): motion + hotend-temp + extrusion only; no firmware/EEPROM writes. license_tier: ORIGINAL
