Hey, I’ve got some part from when I tried to assemble a Darwin – I’ve not had time to finish it and I’m needing to clear out because I’m moving house. They may be of use to someone – sold as pictured Moudlings Electronicsby JoeMcGuire - For Sale
Freds, Cheers - They are a few things I'm working on. In the case of the knight - its imported at that angle I'd like to extend the functionality to allow objects to default rotation to overcome them being on their sides or upside down - but that requires a fair bit or work with the logic and interfaces. For rotating vertically - I've got a few options that I'm weighing up - but i probably wonby JoeMcGuire - Administration, Announcements, Policy
Marcus, Using an applet viewer was certainly an option but I’ve ruled it out on requiring the end user to have java enabled. Also as objects got bigger and more complicated it could begin to lag on a slower computer. There is a good example of a Java3d web applet viewer out there but i can’t find the link right now. I think using JMF to create the video from stills is the probably the best direcby JoeMcGuire - Administration, Announcements, Policy
Hi Freds, That sounds very in the know - have you based it on anything or just a theory? I'll have a go at testing it and see what the results are likeby JoeMcGuire - Administration, Announcements, Policy
haha, of course. Well I’ve never released code before - so i had intended to spend time working out the best method (revision control and hosting service). But vanity aside I can email you the working Java source with some notes. PM me your email if you’re interestedby JoeMcGuire - Administration, Announcements, Policy
Hey Arvin, The still renders are outputted by a Java3D command line app I’ve written which i can pass a STL file + other parameters and it’ll produce a still image or a serious of. Then FFMPEG is used to compile the frames into a video, and finally just a php module uploads to youtube and ties up loose ends. I’m hoping to release the Java Renderer opensource once I have had a chance to clean uby JoeMcGuire - Administration, Announcements, Policy

I've been working on a web service and interface to help people browse and select objects that they’d want to print. It’s in a really early stage but would be awesome to hear if anyone has ideas of what they'd like. So far it just shows (relatively poor) renders of objects at certain angles. But I have plans to improve the renders, add user reviews and ability to upload your own objects. I'm hoby JoeMcGuire - Administration, Announcements, Policy
Sounds like a good idea to me tooby JoeMcGuire - United Kingdom RepRap User Group

I've been working on the RepRap as my final year project for a design degree at Leeds Met. Sourcing Parts ================= PCBs are from Zach store.rrrf.org Electronics are from Mouser in America - shipping +import. I'm think it was cheaper than the UK over all.

I'm look at is enclosing my Darwin with a shell. Which could provide, - the opportunity for design to have a significantly bigger influence on the final form. - Safety The option of a heated chamber to reduce shrinkage To attach a shell I have looked at clips but we ideally need flat surfaces to create a strong connection. I came up with a couple of options to attach flats to the current desiby JoeMcGuire - Mechanics
spcmicro, Great to hear you have the same idea! I'm currently building a physical Darwin and am too on the Y-axis so you are very close to being finished. The idea of scripting the 3d model to actually animating the Darwin building an object is mad! great idea it has never dawned on me as possible. It would be great if you could share the model when you have finished. However if you are williby JoeMcGuire - General
Hey, I am in search of the cad file for the RepRap. Ideally something compatible with 3ds max but anything will do to get me started. To clarify - I'm looking for a cad representation of the RepRap Darwin design. Iby JoeMcGuire - General
Cheers Nophead, I've done that and it seems to be acting alot better. The parts list is wrong. Joeby JoeMcGuire - Controllers
Hi, I am using the recommended 484-0149 ----------------------------------- G550 NTC thermistor,10kohm at 25deg C Manufacturers Part No: B57550G103J ----------------------------------- I have used a 10nf Capacitor for c3by JoeMcGuire - Controllers
Blerik, I had no luck with wiring them as you suggested. can you double check and let me know? Cheers Joeby JoeMcGuire - Controllers
Just to confirm I received Fl57STH51-3008B stepper motors from bitsfrombytes.com. The spec sheet can be found - Can anyone advise how to wire this stepper to a UCB v2.1?by JoeMcGuire - Controllers
Update getting hyperterminal open then lights up both green - although both still very faint.by JoeMcGuire - Controllers
Hi, I am having a similar problem. Without the max232 chip in - the board lights up only the power LED With the max232 chip in one of the bipolar LEDs lights up a faint green. Plugging the serial cable into a live serial port makes no difference. In my case I have not yet tested the serial port as suggested, however I have used it to program a PIC, which suggests it work fine? Any suggestiby JoeMcGuire - Controllers
Cheers guys! Ian, Where did you get JB weld from in the UK? Joeby JoeMcGuire - Mechanics
Hi, I got my kit from bitsfrombytes.com which came with some Nichrome wire. I have never worked with Nichrome wire before but it appears to be uncoated. You may be able to see the wire in the attached photo - which has been badly taken on a mobile phone. If the wire is uncoated am i right to be weary of shorting the circuit? Has anybody set up their extruder barrel with uncoated Nichrome wireby JoeMcGuire - Mechanics
Does the Darwin use a straight rs232 cable? Cheers Joeby JoeMcGuire - RepRap Host
Jay, Nice stuff. I am really pleased to see an eeepc in the background. I don't currently have a laptop to run any of the software on and was considering an eeepc. How does it hold up to the job? Do you run any 3d modelling programmes on it? Joeby JoeMcGuire - Reprappers
I'm not sure what you mean by official ones. But I placed an order, which included the motors, with bitsfrombytes.com at the start of the week. Cheers for your help mouser seem the way forward for me.by JoeMcGuire - United Kingdom RepRap User Group
Green arrow, Thanks for that response, Did you consider ordering from Mouser? I'm weighing up my options. Rapid are out of stock of a couple of the items on your list. Also Mouser will ship to the UK for $25, although I imagine there may be import VAT on top.by JoeMcGuire - United Kingdom RepRap User Group
Ian Eagland, Sorry, your response was a little over my head. Can you confirm if I can use the Arduino (Which I own) as the PIC programmer for the RepRap? Cheers Joeby JoeMcGuire - United Kingdom RepRap User Group
TheFallen I'm very much going to be learning on the go. Will it be easy to replace 5x 0.1ohms resistors - With - 2x 1 ohm resistor in parallel on the boards I have ordered from store.rrrf.org?by JoeMcGuire - United Kingdom RepRap User Group
Hi, Is Arduino decimal a PIC programmer? if not what is the most advisable PIC programmer to buy/make? Green arrow, I'm looking to use your shopping list for Rapid. I've noted what you have said already on this thread - is there anything since, you might have ordered or done differently? Can anyone recommend where to get the 4 pin Molex power connector?
