# FreeCAD macro exporting smooth 3MF files and preserving all slicer print settings,
# with automatic workflow to your preferred slicer.
#
# This macro automates and enhances the 3D printing workflow from FreeCAD to your slicer by:
# • Generating smooth 3D prints without visible facets
# • Preserving print settings (temperature, supports, speed…) directly within the FreeCAD project
# • Launching external programs to streamline the full pipeline:
# Use https://github.com/2cv001/3D_printer_3mf_workflow/blob/main/3D_Printer_3mf_Workflow_ConfigIni.FCMacro
# to add external programs
#tests effectués:
# lancement 1° 2° sans sauver la première, et fois suivantes en sauvant ok
