You already know what it is, but the smal modules and the 1A 1B 2A 2B smell like stepper motor controllers, then there is the Arduino header pattern, so it must be a shield, and arduinos plus lots of steppers it can only be a 3d printer.
unfortunately i'm a slow learner, not as genius as everybody here.
I suspect that not everyone who tags their board as "open source" is crazy about providing "support" to the random people who might have gotten one through Itead's service, though. That a board is "open source" doesn't really imply that it's a "product" somewhere.
correct, its not necessarily about support, but "documentation". whats the point of open source if it doesnt have any documentation or publication? that can be linked to the board to avoid people asking in forum like this, finding the whole world etc. its like announcing "hey! this is open source stuff!", but when asked "what is this?" he keep quiet and swing his head left right.
If they had an inventory of whats available for grabs and let you choose I would go for it, but maintaining and displaying that inventory is work.
i would say, this random board attempt can attract some people, but perharps its not you
its their marketing strategy. but i will agree with you, having freedom to choose which OSHW board to get is better option, ut as you said, it is work.
it is the random assignment/fulfilment that is wasteful and inefficient.... As it now stands I looked at that option and said "I don't want to be surprised" and just ignore it.
since its free, i just clicked the option and ignore it. not that i expect something miraculous happening, i thought if i cannot use it maybe i can work it for my next quick-slap-in protoboard project. but what do you know? as i've been told, this is an arduino mega shield for 3d printer! i got mega, maybe if i got free time i can start building up my own 3d printer (or cnc, xy machine etc) not entirely from scratch. otherwise i may simply ignore it or toss it to the bin, but this one i dont think so (for me). we both may ignore this, the only difference is that "you will not get surprised and got nothing", as for me "i'm surprised and got something and i may choose to use or ignore". but thats not the problem here, its about OSHW documentation. the only time i'll avoid to click the option is when i dont want to share my board, thats all sensible to me, other than that i dont understand why people dont want free stuff that they can bring home.
