Path Post/fr

Description
Cette commande exporte un projet Path sélectionné vers un fichier G-Code.

Each CNC Controller speaks a specific G-Code dialect, requiring a Dialect-correct Postprocessor to translate the final output from the agnostic internal FreeCAD G-Code dialect. Several Postprocessors are provided, allowing direct use, or as templates for modification. Postprocessors contain configuration flags and are designed to be tuned by adding G-Codes and M-Codes to provided definitions for:
 * Machine initialization
 * Job finalization
 * Tool-Changes
 * Cooling on /off
 * Etc...

Postprocessors use the [Path Job Operations FreeCAD G-Code dialect], in conjunction with the Postprocessor configuration definitions, to generate Dialect-Correct G-Code for target machines. This allows the Path workbench to generate correct G-Code to target various CNC machine controllers by invoking different Postprocessors.

CNC Machine Controller types include:
 * CNC mills
 * CNC lathes
 * 3D Printers
 * DragKnife Cutters
 * Laser Cutters
 * Engravers
 * Plasma Torch Cutters
 * Wire Benders
 * EDM Cutters
 * Etc...

If only one CNC machine is used, or if all CNC machines share a common Postprocesor, the Path workbench would need to include only a single Postprocessor. If a single Postprocessor is inadequate to output G-Code for all target CNC controllers, then multiple Postprocessors must be installed.

Utilisation

 * 1) Définissez l'attribut Output File du projet Path que vous voulez exporter
 * 2) Définissez l'attribut de Post Processor de la Machine associée avec le projet
 * 3) Pressez le bouton

Options

 * Si le fichier de sortie et le post-traitement ne sont pas définis dans le projet, le contenu de ce dernier est affiché dans une fenêtre pour vérification
 * Vous pouvez aussi exporter un projet ou tout autre Path directement en G-Code en utilisant le menu Fichier->Export

The provided Postprocessors are written with comments indicating areas containing Flags, Configuration Variables, and Sections of G-Codes and M-Codes that are to be used by the Postprocessor to configure the output.

Typical Configuration True/False Flags include:
 * OUTPUT_COMMENTS (True = Allow, False = Suppress), Used to insert Text Comments in the output G-Code file.
 * OUTPUT_HEADER (True = Allow, False = Suppress), Used to insert Text Headers in the output G-Code file.
 * OUTPUT_LINE_NUMBERS (True = Allow, False = Suppress), Used to insert Line Numbers in the output G-Code file.
 * SHOW_EDITOR (True = Allow, False = Suppress), Used to show the output G-Code in a Pop-up window when invoking the Postprocessor.
 * MODAL (True = Allow, False = Suppress), Used to reduce the number of output G-Code lines by stripping Mode information when the Mode is not changing.

Typical Configuration Variables include:
 * LINENR (Line Number), Used to Set the Line Number index.
 * UNITS (G20 or G21), Used to explicitly communicate to the target CNC controller what Units to use to interpret the final output file.
 * MACHINE_NAME (Name of Target CNC Mill), Used to Insert a machine name label in the final output file.
 * PRECISION, Used to Set the number of digits to include after the decimal place in final output file

Typical Configuration Sections include:
 * PREAMBLE (Code configuration inserted at beginning of the Job)
 * POSTAMBLE (Code configuration appended to the Job, providing for parking the machine, etc...)
 * TOOL_CHANGE (Code inserted with each tool change in the Job)

The Edit->Preferences...->Path->Job Preferences tab, Defaults->Path is used to set the default Postprocessor selected on Job creation. This allows Path workbench to be configured to only display desired Postprocessors, and to set a default.

Do not use the File->Export menu for export to G-code, it will produce damaged G-code!
