One where the parents, children, and new seeds can register so that we can see the evolving progress, or lack thereof. It can be a way of motivating ourselves, seeing the children and grandchildren spread etc. Without it we have no way of measuring one of the core reprap goals.Murrayhttps://www.blogger.com/profile/13533904387867916267noreply@blogger.comtag:blogger.com,1999:blog-5483471752664961069.post-46736105696151875702010-08-16T07:29:59.786-07:002010-08-16T07:29:59.786-07:00+1 for the idea of a tested,packaged extruder that...+1 for the idea of a tested,packaged extruder that works with a conventional cnc 3 axis mill.<br /><br />I am a hobbiest, and have created my own 3-axis router. it works great and uses primarily 'standard' parts and EMC2 for control.<br /><br />If there had been an EMC compatible, turn-key extruder that bolts on as an axis, i'd have been willing to pay $200 or so for such an assembly. But there wasnt. This is because Repraps' formal goals are self-printing. Thus, there are a lot of unorganized hackers out there working to make repstraps, but they all 'abandon' perfectly good machines because they are not a 'real' reprap.<br /><br />But, since there were not such products, i ended up doing what it seems others have done: i created my own project with the<br />goal of creating an extruder who's design and controls are <br />intended to act on an existing 3-axis platform:<br /><br />http://cncfdm.blogspot.comDavehttps://www.blogger.com/profile/11987514110079695313noreply@blogger.comtag:blogger.com,1999:blog-5483471752664961069.post-11855870586641866332010-08-15T13:10:44.400-07:002010-08-15T13:10:44.400-07:00It took me well over a month to build my mini mend...It took me well over a month to build my mini mendel and get it printing, and I was tooling around with ideas for a repstrap for some time before that. Things picked up considerably once I realized that I could get parts from mcmaster locally, but sourcing parts, especially with budget considerations to think about, can take some time. Once the RP parts, rods, bearings, belts, nuts and bolts are procured, it shouldn't take more than a weekend to build, but after building I also had trouble with the electronics and then with the software that delayed me. Then I had a hell of a time trying to build a reliable extruder and hot-end, and when I finally did, it required machining metal parts in ways that many users will not be ready to do, and that I wasn't ready to do when I started.<br /><br />I guess what I'm saying is, do you know why your mendel sets aren't printing? It may be because people lost interest, but it could also be that they need help getting it working, or do not yet have the budget for some of the parts they need. Given your "hackerspace with multiple members" requirement, it may turn out to be reasonable, but I don't think it's a good idea in general to assign deadlines for a project that still takes so much hacking to get working.<br /><br />As a side note, I suspect that the thing that would be most helpful to getting repraps and repstraps printing in the wild would be to sell fully assembled and TESTED extruders (including a reliable, non-nichrome hot end). This would allow existing cartesian bots, for which there are may designs online, to become repstraps.whosawhatsis?https://www.blogger.com/profile/12792264289634575186noreply@blogger.com
