<h2><span class="mw-headline" id="Description">Description</span></h2>
|
|
<p>This command exports the selected <a href="Path_Job.html" title="Path Job">Job</a> to a G-code file.
|
|
</p><p>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.
|
|
</p><p>Typical functions of the Postprocessor include:
|
|
</p>
|
|
<ul><li>Using a correct Job output G-Code file extension. </li>
|
|
<li>Selecting the G-Code commands. CNC controllers typically support a subset of available G-Code commands. The super-set of G-Code commands contains powerful and specialized commands that otherwise must be processed using multiple simpler commands. Postprocessors are written to select the best G-Code for an Operation, available on the target. </li>
|
|
<li>Formatting the G-Code syntax by reordering the Feed, X, Y, Z, A, and B inputs, and the precision.</li>
|
|
<li>Inserting a Pre-amble to set units, units format, Work plane, coordinate system, etc...</li>
|
|
<li>Inserting a Post-amble to park the machine, stop it, process any arguments. </li>
|
|
<li>Inserting Tool changes, or suppressing them between subsequent operations using the same tool.</li>
|
|
<li>Formatting the Feed and Speed rate information to revolutions per minute, or per second.</li>
|
|
<li>Formatting Function Call Naming and Calling.</li></ul>
|
|
<p>Several provided Postprocessors generate suitable code for many CNC controllers, or can be used as templates for modification
|
|
</p><p>Postprocessors contain configuration flags and are designed to be tuned by adding G-Codes and M-Codes to provided definitions for:
|
|
</p>
|
|
<ul><li>Machine initialization</li>
|
|
<li>Job finalization</li>
|
|
<li>Tool-Changes</li>
|
|
<li>Cooling on /off</li>
|
|
<li>Etc...</li></ul>
|
|
<p><br />
|
|
Postprocessors use the [<a rel="nofollow" class="external text" href="https://www.freecadweb.org/wiki/Path_scripting#FreeCAD.27s_internal_GCode_format">Path Job Operations FreeCAD G-Code dialect </a>], 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.
|
|
</p><p>CNC Machine Controller types include:
|
|
</p>
|
|
<ul><li>CNC mills</li>
|
|
<li>CNC lathes</li>
|
|
<li>3D Printers</li>
|
|
<li>DragKnife Cutters</li>
|
|
<li>Laser Cutters</li>
|
|
<li>Engravers</li>
|
|
<li>Plasma Torch Cutters</li>
|
|
<li>Wire Benders</li>
|
|
<li>EDM Cutters</li>
|
|
<li>Etc...</li></ul>
|
|
<p>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.

<p>Output file and Postprocessor properties can be set in the <a href="Path_Job.html" title="Path Job">Job</a>, at any time, prior to invoking the Postprocessor.

|
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.
|
|
</p><p>Typical Configuration True/False Flags include:
|
|
</p>
|
|
<ul><li>OUTPUT_COMMENTS (True = Allow, False = Suppress), Used to insert Text Comments in the output G-Code file.</li>
|
|
<li>OUTPUT_HEADER (True = Allow, False = Suppress), Used to insert Text Headers in the output G-Code file.</li>
|
|
<li>OUTPUT_LINE_NUMBERS (True = Allow, False = Suppress), Used to insert Line Numbers in the output G-Code file.</li>
|
|
<li>SHOW_EDITOR (True = Allow, False = Suppress), Used to show the output G-Code in a Pop-up window when invoking the Postprocessor.</li>
|
|
<li>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.</li></ul>
|
|
<p>Typical Configuration Variables include:
|
|
</p>
|
|
<ul><li>LINENR (Line Number), Used to Set the Line Number index.</li>
|
|
<li>UNITS (G20 or G21), Used to explicitly communicate to the target CNC controller what Units to use to interpret the final output file.</li>
|
|
<li>MACHINE_NAME (Name of Target CNC Mill), Used to Insert a machine name label in the final output file.</li>
|
|
<li>PRECISION, Used to Set the number of digits to include after the decimal place in final output file</li></ul>
|
|
<p>Typical Configuration Sections include:
|
|
</p>
|
|
<ul><li>PREAMBLE (Code configuration inserted at beginning of the Job)</li>
|
|
<li>POSTAMBLE (Code configuration appended to the Job, providing for parking the machine, etc...)</li>
|
|
<li>TOOL_CHANGE (Code inserted with each tool change in the Job)</li></ul>
|
|
<p>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.
|
|
</p><p>Included Postprocessors are saved in the FreeCAD.Mod.Path.Pathscripts.Post by default:
|
