Descrizione
Questo comanda esporta una Lavorazione selezionata in un file di codice-G
Ogni controller CNC parla un dialetto G-Code specifico, che richiede un postprocessore dialettale corretto per tradurre l'output finale dal dialetto G-Code di FreeCAD agnostico interno.
Typical functions of the Postprocessor include
- Using a correct Job output G-Code file extension.
- 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.
- Formatting the G-Code syntax by reordering the Feed, X, Y, Z, A, and B inputs, and the precision.
- Inserting a Pre-amble to set units, units format, Work plane, coordinate system, etc...
- Inserting a Post-amble to park the machine, stop it, process any arguments.
- Inserting Tool changes, or suppressing them between subsequent operations using the same tool.
- Formatting the Feed and Speed rate information to revolutions per minute, or per second.
- Formatting Function Call Naming and Calling.
Postprocessor Customization
Note: Several provided Postprocessors generate suitable code for many CNC controllers, or can be used 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 FreeCAD's internal 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.
Utilizzo
- Selezionare la Lavorazione che si desidera esportare
- Premere il pulsante Post elaborazione
- Confermare il nome e la directory del file di output
Opzioni
- Se le proprietà del file di output e del post-processore non sono impostate nel Progetto, il contenuto del progetto viene invece mostrato in una finestra di dialogo per la verifica
- È anche possibile esportare un progetto o qualsiasi altro percorso direttamente in Codice G utilizzando il menu File-> Esporta
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.
Included Postprocessors are saved in the FreeCAD.Mod.Path.Pathscripts.Post by default:
- centroid
- comparams
- dynapath
- grbl
- linuxcnc
- opensbp
- phillips
- rml
- smoothie
Limitations
- Do not use the File → Export menu for export to G-code, it will produce damaged G-code!
