# Profil PrusaSlicer (CLI) — FLSun QQ-S sous Klipper, TPU 95A, buse 0.4
# Derive de qqs-pla-prod.ini. Usage :
#   ./PrusaSlicer.AppImage --export-gcode --load slicer/qqs-tpu.ini modele.stl --output gcodes/x.gcode
#
# Contraintes de CETTE machine, qui dictent tout ce qui suit :
#  - extrudeur BOWDEN (~700 mm de PTFE) : le TPU se comprime dans le tube au lieu
#    d'avancer -> vitesses divisees par ~2.5 et retraction courte.
#  - hotend V6 clone a gaine PTFE : plafond ~245 C en consigne, jamais plus.
#  - premier essai : on ne cherche PAS les cotes, on cherche a extruder proprement.

# --- imprimante (identique PLA) ---
