I hate trying to line up double sided boards so I try like heck to only make single sided boards but this might just be the ticket to doing double sided boards and give me that extra push to try some new stuff.Anonymoushttps://www.blogger.com/profile/00994255749068724416noreply@blogger.comtag:blogger.com,1999:blog-6607394033450724549.post-8775876423721811982013-05-12T08:19:08.238-07:002013-05-12T08:19:08.238-07:00This comment has been removed by the author.Anonymoushttps://www.blogger.com/profile/03989507044372732545noreply@blogger.comtag:blogger.com,1999:blog-6607394033450724549.post-77061202851335862832013-05-12T02:50:17.070-07:002013-05-12T02:50:17.070-07:00Nice project.

If you're not careful - the reflected light will melt tubing / other laser cutter parts (voice of experience).<br /><br />FR4 itself is also very difficult (and probably toxic) to cut.<br /><br />Not discouraging anyone else from trying - I've just had trouble getting useful results.<br /><br />-RichRich Olsonhttps://www.blogger.com/profile/08755861816407417985noreply@blogger.comtag:blogger.com,1999:blog-6607394033450724549.post-3244827632268024322013-05-07T06:21:55.027-07:002013-05-07T06:21:55.027-07:00I like your idea of making a positioning jig first...I like your idea of making a positioning jig first. I would have attempted to go straight for some screw holding device, create a board out of a much large piece of FR4 and then cut the excess off. But then I would be cutting a complete board - one wrong move with that saw and it's damaged :) <br /><br />Do you think the laser may be powerful enough to ablate the copper itself if you used, say, a scissor-cut thin copper clad (forgot the official name - a very thin board sheet). I'm curious about any technique that exists which could eliminate the need for etching.<br /><br />Thanks!ElectroNickhttp://www.electrondepot.com/noreply@blogger.com
