Questions on using a moving gantry style mini-mill...

You can edit the post.

Look in the post processor manual. There's a variable called "file notes" that you can add.
In Cut 2D or V Carve Pro, go to Edit > Notes and put your G5x there.
Then the notes will be inserted in the g-code wherever you put the "file notes".

OOH, nice ;)

Didn't notice the post manual before.

I see there is possibly a more useful one called [TOOL_NOTES] that goes with each tool used, the post wraps the message in brackets which are ignored by Mach so it will need some editing which will then render the [TOOL_NOTES] feature useless for tool notes but hay-ho you can't have it all I guess ;)

Just insert the tool_notes var into the tool change part of the post, as i want add a macro call to go to park position and then a pause to remind me to change hold-down clamps etc before changing the tool and continuing.

That depends on what you want to do.
For adding a G5x, I think the file notes are a better choice.

For the park position, add the M883 at the start of your tool change section in the post, followed by your pause.

Its more complex as usual :)

The park position is only needed on a couple of jobs which need to be part machined then the clamping moved around and the tool changed then the finish cuts made.

There are three options i see tool_notes, toolpath_notes and file_notes - all look useful.
The G5x only needs calling at the start of one particular file.
