Robots arms have at the moment proven unsucsessfull, either too much money or to build it cheep enough be a heck of alot of work for me. Thinking maybe ajoint on the z axis, at the moment the z axis moves the board up and down, im going to try and move the arm up and down, if i get sucsess with that i'll try to add a joint thats capable to attack the object at 90 degrees. in theory we could go fuby Noz - General
been working with a arm7tdmi chip lately, actually ive been using a CAN chip with it. Not a bad sized amount of onboard memory. If it goes this way i can help sorting out the memmory map, possible even migrate the code from the current board onto the new board. Still liking the CAN idea better, get the PC to do more of the workload, PC is a heck of alot more powerfull, and easer to work with (iby Noz - General
Ive just happened to write a microcan open protocol in the past month CAN started off in cars,breaks,engine management,and ive read in a couple of places electric windows So i would of thought there would be someone willing to make steppers. If we wanted much much cheeper controller we could chuck a arm7 on a board ( aboutby Noz - General
Very intreasting , i could only read the abstract as well, but ive heard of this kind of stuff before. A CAN network might work well, worth exploring anyways servo or stepper motors are fine , i can work with either but i cant see for any reason if i find one i cant find the other. There are hundreds of CAN shaft encoders out there so im guessing i'll find motors soon enough, main problem isby Noz - General
that i did not know, guessing hes using the serial or spi,emi type of config. Zachs got a picture in his head but i dont see it yet . I Think i'll still try to find some CAN motors. Who knows it might have some benifits that people would want, anouther mutatoin to the cause.by Noz - General
Ahh the catch 22! Im trying to avoid the pitfalls of a microcontroller! dont get me wroung, there great, so are the drives, my job is to make new software in embeddid C. I work with simple PIC's, ARM's (7 and 9 mainly),drives,lcd drivers etc all day long. Im not a expert but i got a good idea of strengths and weakness's. If reprap was going to never be addid to then i would do that route, but iby Noz - General
Been going through alot of stuff,premade stuff is either beyond budget or useless for the task. The current electonic setup, i think uses all the pins, most of the memory etc, So would be diffacult to add anouther degree of freedom. ALTHOUGH at the moment im trying to find a company with motors with CAN interface, ive heard people talking about them but i cant find them. Means if people wantedby Noz - General
before i begin i thought i would say that tinkit.it.com (uk)have some adrinio boards, and sorry for the spelling etc , im very tierd. ive been trying to explore milling for the reprap, but no matter how i tryed to work it out for good and accurate 3d modals we'll probably need multiple heads other than the extruder, and add anouther degree of freedom ( eg we can mill some layers as there put dowby Noz - General
Sheffield is a little out the way for me (london) so could it be more of a pub lunch ? I would like to just have a chat to people who have already made one too see how i can improve with my oneby Noz - United Kingdom RepRap User Group
I defently will contribute, Ive got some ideas but im going to go off on a slightly differnt tangent, So work could possibly be combined later on. Im guessing people often come on here full of ideas,in which others help and then they go and nothing happens, i want to show im commited before i start talking to muchby Noz - General
Just looking at the parts in "The RepRap Research Foundation" shop and i was wondering if there was a compleate kit avaiable? I was looking around but i dont seem to be able to find a "full kit" or any bits like the pipes and stuff ( i know i could attempt to get pipe and drill it) but if i make any mistakes i probably wouldnt realise it. i know there available from the other shop.

Hello all, Long time listener ,first time caller. Ive been reading up on this site for a while now and as someone with no experiance in this type of thing, i found it a little bit diffacult So i hoped someone could awnser my questoins and maybe make this into a sticky type of thing for new users? 1. The current latest versoin of the reprap idea is darwin 1.2? 2. it works by moving in tby Noz - General
