wow, thats great news. i love reading your thoughts and progress on this. its definitely an area i would have no idea about getting into... but it seems like a very promising area. have you looked at backyard foundry sites for doing metal casting at home? apparently they are VERY easy and can do stuff like aluminum, brass, etc.by ZachHoeken - Polymer Working Group
sweet! that does change things. very exciting. do you have any links?by ZachHoeken - Developers
yeah, that is definitely one of the reasons syringes were abandoned in favor of a thread driven filament extruder. you just cant store too much in a syringe. however, there are bigger ones out there... i found a 150cc syringe last night that looked pretty good. another idea i had, which is a post v1.0 idea is to try and reprap our own syringes... then we could do a large, gallon syringe with tby ZachHoeken - General
hey, sorry if i'm forgetting something, but there are a couple new people in the wiki that want to help out with the wiki, particularly on the materials pages. this is particularly exciting since one is a chemist and they both really know their stuff. ~Zach _______________________________________________ Developers mailing list Developers@by ZachHoeken - Developers
cool! if you're in the USA and would like me to ship you some syringes and a few different needle sizes to test with i'd be happy to. or you could go to but you'll have to buy a few boxes of needles to get different sizes. still pretty cheap ($3-4/box) the biggest syringe i can find on the net is 100cc, but they only sell up to 60cc. anyone know where we can find larger syringes?by ZachHoeken - Polymer Working Group
hiya! thanks for the heads up... its a bit of a short timeframe, but we'll see if we can get something whipped up by then.by ZachHoeken - General
that would be really cool. we have some pages detailing types of materials that can be used in the wiki... its pretty decent, but could definitely use some sprucing up. personally, i dont know much about chemistry... so i cant do it myself, but it would be amazing if one of you guys wanted to take a crack at it. we hid the wiki registration link to keep the spambots out, but send me a PM and iby ZachHoeken - Polymer Working Group
yay! welcome to the community. we're working our butts off right now trying to get ready for the release of v1.0. technically, we've set a release date of 2008, but *unofficially* its looking like we'll be making a 1.0 release thats ready to rock and roll in late may / early june. we will have boards available for purchase by the end of april. so at the very least you could get those, and meby ZachHoeken - Reprappers
ah yes... that is a good idea there. if you simply print more brackets... you can be printing more of the time, while the other areas are doing their cooling. it also may be an adhesion problem... but either way its looking very cool! the people at my workplace are very excited about it. this is going to be huge. ~Zach On 28 Mar 2007 02:50:26 +1200, RepRap Forum Mailer wrote: > Author:by ZachHoeken - Developers
awesome!! like adrian said, this website is a complement to the objects wiki... the idea here is that the bulk of the information about a certain part is stored on the wiki, and this DB simply stores relationships between parts and also supplier information. wiki's are great for collaboratively editing content... they suck for storing relational data. i also want to create an embeddable scriptby ZachHoeken - Developers
well, thats basically what we're doing right now... except with the wiki its not in a database. since its not in a database, we have to do everything manually. we have parts lists for various parts of the system (extruder, boards, etc) scattered across each various page. thats fine for us, since we generally know whats going on and have been buying these things piecemeal anyway. however, for sby ZachHoeken - Developers
heres the difference: the parts db is simply a listing of the components broken down into what makes up what. think the parts lists that are on say the universal board page. it will contain the name of the object, an optional short description, links to its detail pages (objects.reprap.org), subversion, etc. the main meat of the parts db is simply to tell people what the objects consist of,by ZachHoeken - Developers
Hey All, With the influx of new members, (and the influx of their first question: is there a list of parts i need?) I've decided to dust off the old objects site. I'm re-purposing it as a Parts DB instead of a community oriented site... i think the forums / wiki fill that nice quite nicely. Instead, it will simply be a list of parts, suppliers for those parts, and most importantly it will beby ZachHoeken - Developers
hmm. i'll have to get some and play around with them after v1.0. did you hand solder them, or use the toaster oven trick? i bet a syringe + solder paste + toaster oven would work pretty well.by ZachHoeken - General
are there any larger magnetic encoder chips out there? its hard to imagine that NOBODY would produce oneby ZachHoeken - General
hey. glad to have another repstrapper here on board. i'm very happy to see another member joining the movement. anyway, if you'd like to stay compatible with the project, i would highly suggest using our boards and software, and just hacking together your own 3d cartesian robot. that way you only have to 'steal' the software / electronics. if you're not comfortable with making your own boardby ZachHoeken - Reprappers
wow, i agree with corey that you know your stuff... i looked up furfural on wikipedia and found this: Furfural, as well as its derivative furfuryl alcohol, can be used either by themselves or in together with phenol, acetone, or urea to make solid resins. Such resins are used in making fiberglass, some aircraft components, and automotive brakes. thats super cool! should be some fun stuff to plby ZachHoeken - Polymer Working Group
no, please keep posting the results / findings. i may not understand all of it, but someone out there might. you're providing a valuable service to the rest of the RepRap community!by ZachHoeken - Polymer Working Group
on the magservo part... check out our wiki... theres a couple writeups in there on turning a cheap dc motor into a stepper. we're planning on using those in reprap v2.0 due to cheapness, etc, but decided to opt for steppers just because they are essentially plug and play. forrest is actually using them on his and apparently they work very well... magnetic shaft encoders with 1024 step resolutioby ZachHoeken - General
and for OSX users there is support built into iMovie, or you could dish out $35 to get the highly rated Boinx iStopMotion. pretty rad.

thats some excellent information... i'm excited to see how it works out for you. would you like me to send you a variety of syringe needles and tubes? it would save you having to buy $70 worth just to do some experiments.by ZachHoeken - Polymer Working Group
thanks for the suggestions! after my failed attempts drilling out the nut, i've looked into alternative nozzles. i'm definitely interested in these... it seems like this would be an ideal alternative to doing it at home. especially if its so cheap. as for the electronics... we're ordering printed boards and will be able to simply provide them for super cheap. then its just a simple solderinby ZachHoeken - General
hey, thanks for your interest in the project! right now we're working on the parts list. we're actually pretty close. the circuit boards are on their way, and the mechanicals are generally nothing more than the printed parts, rods, nuts, bolts, motors, and wires. i'm going to look into making that online parts-list service... it would be nice to be able to have an easy way to keep it up toby ZachHoeken - Reprappers
very nice.... i think you accurately describe the way many on this project feel about it. personally, i'm both excited and wowed by the potentials the future holds. this project in particular provides an amazing potential to change the way people interact with their technology and also physical objects.by ZachHoeken - General
that is an excellent idea and one i personally support and one that would be interesting to experiment with. however, we went with a cartesian robot because of the simplicity. once we get the machine out into the wild, you should definitely try and develop the parts in thermoplastic. i'd imagine a easy way to produce robotic arms would be very exciting.by ZachHoeken - General
so what is the solution? do we leave out R3? we'll need to update the build instructions.

kits are definitely an excellent idea. i'm all for it. its nice because when you order in bulk like that, you can get some REALLY nice discounts. lets call that 'power of the crowds' add that in with the 'wisdom of the crowds' and you have a system where everyone is looking for (and sharing) the lowest price possible. that is true market economy right there =) it does create a decent amountby ZachHoeken - Reprappers
hey phil, sorry about the delay... basically i think why they are different is because they were set up by different people. i think simon was more familiar with twiki so he went with that, while sebastian was more familiar with mediawiki. feel free to contribute to both of them... i dont think there are plans to consolidate either wiki, so dont worry about potentially losing any data =) ~Zacby ZachHoeken - Reprappers
Hello, I was browsing your website, looking for information about nozzles. Your page describing your dispensing nozzles has just what I was looking for: I was wondering if you could give me a price list for a variety of sizes (0.1mm to 1.0mm) and in a variety of quantities (10, 25, 100, 1000) Also, what threading sizes do you offer on your nozzles.
