I have a shipment of those driver chips at the post office that I need to pick up, but since that's not going to be a viable solution-- I do feel a certain amount of responsibility and while I do not currently have cash this week i would probably be able to finance this in a week or two. Let me discuss the purchase with my partner before i commit though. <br>Brendan </div></div><div dir="ltr"><hr><span style="font-family: Calibri,sans-serif; font-size: 11pt; font-weight: bold;">From: </span><span style="font-family: Calibri,sans-serif; font-size: 11pt;"><a href="mailto:sudo-discuss-request@lists.sudoroom.org">sudo-discuss-request@lists.sudoroom.org</a></span><br><span style="font-family: Calibri,sans-serif; font-size: 11pt; font-weight: bold;">Sent: </span><span style="font-family: Calibri,sans-serif; font-size: 11pt;">1/8/2015 10:14 PM</span><br><span style="font-family: Calibri,sans-serif; font-size: 11pt; font-weight: bold;">To: </span><span style="font-family: Calibri,sans-serif; font-size: 11pt;"><a href="mailto:sudo-discuss@lists.sudoroom.org">sudo-discuss@lists.sudoroom.org</a></span><br><span style="font-family: Calibri,sans-serif; font-size: 11pt; font-weight: bold;">Subject: </span><span style="font-family: Calibri,sans-serif; font-size: 11pt;">sudo-discuss Digest, Vol 27, Issue 4</span><br><br></div>Send sudo-discuss mailing list submissions to<br> <a href="mailto:sudo-discuss@lists.sudoroom.org">sudo-discuss@lists.sudoroom.org</a><br><br>To subscribe or unsubscribe via the World Wide Web, visit<br> <a href="https://lists.sudoroom.org/listinfo/sudo-discuss">https://lists.sudoroom.org/listinfo/sudo-discuss</a><br>or, via email, send a message with subject or body 'help' to<br> <a href="mailto:sudo-discuss-request@lists.sudoroom.org">sudo-discuss-request@lists.sudoroom.org</a><br><br>You can reach the person managing the list at<br> <a href="mailto:sudo-discuss-owner@lists.sudoroom.org">sudo-discuss-owner@lists.sudoroom.org</a><br><br>When replying, please edit your Subject line so it is more specific<br>than "Re: Contents of sudo-discuss digest..."<br><br><br>Today's Topics:<br><br> 1.

This would give us full access to their software<br>suite / print driver, and a reliable machine.<br><br>The other option, suggested by rayc is to use an arduino, stepper<br>controllers and a g-code generating toolchain to run the machine.<br>While I don't see any reason why that couldn't work, I feel like that<br>might be a bit awkward for people who wish to use the cutter, and<br>further makes the guide I wrote kind of useless.<br><a href="http://hack.rit.edu/tools/full-spectrum-laser-cutter/">http://hack.rit.edu/tools/full-spectrum-laser-cutter/</a><br><br>As a community, what do y'all believe is best?<br><br>Cheers,<br>-Adam<br><br><br>---<br>Aperture Systems: Redefining Radiography - <a href="http://aperture.systems/">http://aperture.systems/</a><br><a href="http://adammunich.com/">http://adammunich.com/</a> - Cell: +1-650-452-0554<br><br>Be ? knowledgeable ? social ? patient ? fearless ? compassionate ?<br>fun ? humble ? forgiving.<br><br>Be a leader<br>-------------- next part --------------<br>A non-text attachment was scrubbed...<br>Name: 10928062_840794585984965_115321104_n.jpg<br>Type: image/jpeg<br>Size: 153064 bytes<br>Desc: not available<br>URL: <<a href="http://lists.sudoroom.org/pipermail/sudo-discuss/attachments/20150108/03e76212/attachment.jpg">http://lists.sudoroom.org/pipermail/sudo-discuss/attachments/20150108/03e76212/attachment.jpg</a>><br>-------------- next part --------------<br>A non-text attachment was scrubbed...<br>Name: 10933145_840794599318297_1198641389_n.jpg<br>Type: image/jpeg<br>Size: 81658 bytes<br>Desc: not available<br>URL: <<a href="http://lists.sudoroom.org/pipermail/sudo-discuss/attachments/20150108/03e76212/attachment-0001.jpg">http://lists.sudoroom.org/pipermail/sudo-discuss/attachments/20150108/03e76212/attachment-0001.jpg</a>><br><br>------------------------------<br><br>_______________________________________________<br>sudo-discuss mailing list<br><a href="mailto:sudo-discuss@lists.sudoroom.org">sudo-discuss@lists.sudoroom.org</a><br><a href="https://lists.sudoroom.org/listinfo/sudo-discuss">https://lists.sudoroom.org/listinfo/sudo-discuss</a><br><br><br>End of sudo-discuss Digest, Vol 27, Issue 4<br>*******************************************<br></div></blockquote><blockquote type="cite"><div><span>_______________________________________________</span><br><span>sudo-discuss mailing list</span><br><span><a href="mailto:sudo-discuss@lists.sudoroom.org">sudo-discuss@lists.sudoroom.org</a></span><br><span><a href="https://lists.sudoroom.org/listinfo/sudo-discuss">https://lists.sudoroom.org/listinfo/sudo-discuss</a></span><br></div></blockquote></body></html>
