Hi, you can open a topic in our new forum, check here:
https://www.ltspiceusers.ch/#dxf2gcode.68

But i know that i just discussed this with someone else in the old section. Check here first:
https://groups.google.com/g/dxf2gcode-users/c/UY0KVPd0CQg

However if there are additional questions, just open one in the new forum we dont want to continue with google groups, as they are not that easy to search etc.

regards
Christian

 Running dxf2gcode with --quiet flag is not really quiet. It needs to open GUI for a brief moment to initialize graphic objects.
 Thus, if you want to run with no physic display, run it with a virtual display like xvfb

...and here's an attached screenshot image of the fixed DXF file in dxf2gcode, showing the corrected 0,0 origin point

Hi David, I'm a new user of dxf2gcode so I'm not an authority, but I opened your DXF file and noticed that the design sketch is 180 inches wide, so the drawing scale is probably different than you anticipated. The instrument panel cutout being 15 feet wide (!!) for a 3018's twelve inch work area is going to be a problem, in addition to the zero axis point location.

But yes, I can see what you mean about the 0,0 origin point being way off to the lower left -- that is something that can/should be be changed in the original DXF file, and dxf2gcode will display it correctly. I went ahead and fixed it for you quickly, and attached a new DXF file to this reply (but I still think the scale is way off and this needs to be redesigned). Hope this helps.

Forgot the dxf file

I received a dxf cutout from a manufacturer for an aircraft panel instrument. DXF2GCODE generated code where the 0,0 point is so far away that the dimensions of the object itself as seen from the 0,0 position exceeds the side of my CNC 3018 test machine.

How and where in the workchain do I move the 0,0 nearer to the lower left corner of the object?
I am using FreeCAD > DXF2GCODE > Candle Grbl 1.1
