It's a pleasure.

one last question, it looks like the inputs into the menu are imperial not metric. is this correct?

HI Andy
No, most of the plugin's are in drawing units, so they work with both Imp\Metric drawings.

ok thanks, is there a guide or video on how to use this?

the setting are pretty simple, but once I click ok nothing happens.

im going to make a video once I get this sorted and get the cutting right.

the file in question

Hi Andy
In the CB file I downloaded, there were tool Drag knife paths, but they were large.
I used the plugin with the settings in the pic.

what I don't understand is why isn't there a job under machining that I can generate gcode?

when you select drag knife how do you get gcode?

At the top of the page here;
http://www.atelier-des-fougeres.fr/Cambam/Aide/Plugins/DragKnife.html

It says,

"This plugin takes selected polylines and generates new polylines that will be used to creates drag-knife tool path.
From the tool path polyline, an engrave MOP must be used to create the actual tool path and G-code."

My advice is therefore to do this;

1. Get your geometry in place, e.g. some text you want to cut out with the drag knife, and convert it to polylines if not already in that form.
2. Make a new layer and set it to be the 'active' layer.
3. Run the Drag Knife plugin, adjusting the parameters to suit.
4. A new set of polylines suitable for the drag knife to follow will be produced in the new layer.
5. Use an 'engrave' machining operation on those polylines to produce the g-code
