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

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. jacques hol(a)gaskill.com wrote: On Mon, Jan 22, 2018 at 10:27 AM, <hol(a)gaskill.com> wrote: i know printing a dxf as an .xps document works if you have CAD On 2018-01-20 08:17, jacques revera wrote: Which format?

I don't know anything about the machinery available at SUDO room or these kind of file formats.

If it's not too big we could just order it from e.g. seeedfusion as a circuitboard design with no exposed copper pads.

It would be convenient if the SUDO room has some FR4 but as long as the material is opaque, heat proof and can be painted black, should be no problem. This plate will sit at the top center of the scanner. The plate also serves to block light from entering from the top direction. Since, we need to attach something to raise the lights higher than the original hackerspace design, we should not cut this out yet. It does not need to be the same shape as the archivist plate as long as the socket mounting holes are the same. Jonathon wrote last week: ."..you can move the lights further away from the platen. Because of various design constraints, Daniel put the lights closer to the platen than is ideal on that model. For later models (like Daniel's Archivist design), the lights were been moved further away to reduce glare and hot spots. You want to reproduce this in some way. So just build a simple frame you can set on top of the scanner to lift the lights. There is a mathematical way to find the minimum distance, but it might be easiest just to do it empirically, pulling the lights away and taking sample photos until you see that there is no reflected light source." You can see how this the lights are put together on the archivist about halfway down this page http://diybookscanner.org/archivist/index9bef.html?page_id=54 [3] Jacques _______________________________________________ sudo-discuss mailing list sudo-discuss(a)lists.sudoroom.org https://sudoroom.org/lists/listinfo/sudo-discuss [4]
