How to list post-processor arguments?

In the Job Edit pane, in the Output tab, move your mouse over the Arguments field. A tooltip will appear with the allowed arguments.

I use FreeCAD < 1.0, is this postprocessor working?

Probably not as the API has changed a lot with FreeCAD 1.0. You can use the old version of this postprocessor from old branch.

I want to use the 200W module

Add argument --toolhead=200W for this module. Default is 50W (same as adding --toolhead=50W).

How to add a post-processor argument?

In the Job Edit pane, edit the Arguments field of the Output tab to add arguments, separated by a space:

job-edit-pane

Alternativly, argument list can be modified using the Post Processor Args field of the Job interface:

property-list

I encountered this warning: G0: negative or null speed provided (0.0)

No valid (ie. positive float) rapid speed was provided. Rapid speeds are used to quickly move the toolhead in air.

Vertical and horizontal speed can be set up for each job in the sub-tab Default values of the Tools tab:

tools-tab

I encountered this warning: G1: negative or null speed provided (0.0)

No valid (ie. positive float) feed speed was provided. Feed speeds are used while the toolhead is working.

Vertical and horizontal feed speed (and spindle speed) can be set up for each tool in the sub-tab Tools of the Tools tab:

tools-tab

How to use the post processor without requiring FreeCAD GUI?

Add --no-gui argument to use the post processor without any call to the FreeCAD GUI. It will however disable thumbnail generation (equivalent to --no-thumbnail), and jobs referencing may fail.

Change the extension to .cnc.
