(:P) Brett is stitching together the video footage of its first print; I hope to have it posted sometime tonight. Even though it's printing, it's not quite ready yet. We noticed several things that need changing first; we'll place a notice in the For Sale forum when the time comes. We plan to post the design (Alibre) on the wiki as soon as the first kits go up for sale.</description> <link>https://reprap.org/forum/read.php?152,39285,39285#msg-39285</link> <lastBuildDate>Thu, 23 May 2024 15:23:56 -0400</lastBuildDate> <generator>Phorum 5.2.23</generator> <item> <guid>https://reprap.org/forum/read.php?152,39285,52805#msg-52805</guid> <title>Re: Isaac: a CNCed RepStrap based on the Mendel</title> <link>https://reprap.org/forum/read.php?152,39285,52805#msg-52805</link> <description><![CDATA[ Matthieu Wrote:<br />-------------------------------------------------------<br />> We're making one, but no blog - we should !<br />> <br />> Ok for the support group :)<br /><br /><br />Alright coolness.

We just printed the most complicated ones just to verify our own claims. While we did try to reduce the number of parts and still have them printable, reducing the print volume was not a criteria. I'd guess that good decisions on fill-density would yield strong parts with an reasonably low plastic use.<br /><br />Matthieu,<br /><br />There is much better documentation on our website than the wiki. Yes some of the rod lengths have changed, but none of the critical ones. The belts lengths changed a bit which is why we include them in every kit, along with the y-chassis aka 'smashed-frog'.<br /><br />Vacation would be nice. Between work and the machine shop working Isaac I'm surprised I found time to sleep. So yeah, documentation is a bit lacking, but so far everyone has built the machine with what is listed on the website plus the full 3D models we published on the reprap site.<br /><br /><br />Brett]]></description> <dc:creator>bfleming</dc:creator> <category>General New Machines Topics</category> <pubDate>Wed, 14 Jul 2010 16:48:52 -0400</pubDate> </item> <item> <guid>https://reprap.org/forum/read.php?152,39285,51638#msg-51638</guid> <title>Re: Isaac: a CNCed RepStrap based on the Mendel</title> <link>https://reprap.org/forum/read.php?152,39285,51638#msg-51638</link> <description><![CDATA[ Should be more of it then, what do you people do with your free time ? :)]]></description> <dc:creator>Matthieu</dc:creator> <category>General New Machines Topics</category> <pubDate>Wed, 14 Jul 2010 11:57:12 -0400</pubDate> </item> <item> <guid>https://reprap.org/forum/read.php?152,39285,51621#msg-51621</guid> <title>Re: Isaac: a CNCed RepStrap based on the Mendel</title> <link>https://reprap.org/forum/read.php?152,39285,51621#msg-51621</link> <description><![CDATA[ ... it's vacation-time ;)]]></description> <dc:creator>VDX</dc:creator> <category>General New Machines Topics</category> <pubDate>Wed, 14 Jul 2010 10:10:56 -0400</pubDate> </item> <item> <guid>https://reprap.org/forum/read.php?152,39285,51618#msg-51618</guid> <title>Re: Isaac: a CNCed RepStrap based on the Mendel</title> <link>https://reprap.org/forum/read.php?152,39285,51618#msg-51618</link> <description><![CDATA[ Dear Brett and Todd,<br /><br />Just to let you that we have started the cnc process. We'll let you know how it goes. <br /><br />One quick question, to what extend has the Mendel design been changed compare to the original ? Ie can we follow the mendel wiki for everything else than the assembly detailled for Isaac parts ? Are there changes - rod lengths, belts, whatever - not mentionned on the wiki ?<br /><br />Thanks for the design - is the project on hold ? I notice less activity in the forum nd wiki]]></description> <dc:creator>Matthieu</dc:creator> <category>General New Machines Topics</category> <pubDate>Wed, 14 Jul 2010 09:55:18 -0400</pubDate> </item> <item> <guid>https://reprap.org/forum/read.php?152,39285,47788#msg-47788</guid> <title>Re: Isaac: a CNCed RepStrap based on the Mendel</title> <link>https://reprap.org/forum/read.php?152,39285,47788#msg-47788</link> <description><![CDATA[ Has anyone printed a set of Isaac parts using an Isaac (or using a small huddle of Isaacs in parallel)? If so, how does the build time and total amount of feedstock needed compare to an original Mendel parts set? Does print speed/quality/reliability of an Isaac differ from an "original Mendel"?<br /><br />I realize Isaac was designed primarily for the CNC-capable community (to which I do not belong); I'm just wondering if you feel that you have in any sense improved the overall Mendel design in the process of making it CNC-able. If you have, can you outline what those improvements are? <br /><br />Lastly (for now), could or should some of these Isaac design changes find their way back into a (currently hypothetical) "updated Mendel" design?]]></description> <dc:creator>jmarsden</dc:creator> <category>General New Machines Topics</category> <pubDate>Tue, 08 Jun 2010 01:35:15 -0400</pubDate> </item> <item> <guid>https://reprap.org/forum/read.php?152,39285,46450#msg-46450</guid> <title>Re: Isaac: a CNCed RepStrap based on the Mendel</title> <link>https://reprap.org/forum/read.php?152,39285,46450#msg-46450</link> <description><![CDATA[ We do not <i>currently</i> have an extruder, but one <i>may</i> be in the future.

This is a Mendel derivative and will have nearly all the same abilities as the original. We changed pretty much every single part (sans simple clamps) to make it easier to machine.<br /><br />All the critical dimensions for the Mendel have been maintained so that our parts could be substitute with original parts, not on a per-part basis but definitely on a per-assembly basis. So if you really wanted you could replace the z-motor and z-tensioner on our with the original with no side-effects. <br /><br />Also every single one of our parts is printable on a Mendel sized machine, this means you can print another one from ours to truly be self replicating.
