[sudo-discuss] DXF or SVG or? for scanner light fixture mount cutting for book scanner

[jacques revera]

Thanks hol.

Does the SUDO have a machine to cut FR4 from a file? To do that, should I
ask for a DXF or SVG file or something else? This is outside of my ken. Can
someone else decide that and email me so I can ask for the file - and cut
this little piece this week? I can help.

Lighting assembly parts and cameras supposed to arrive today.
