Short Summary

My name is Elvira Yang, many of you know me as a hardware manufacturer and from my online shop www.reprapdiscount.com A friend and me, we got an ideea about developing a board which we believe to cover most of the needs of the reprap community for now and for the future.
It's done, and we call it RUMBA

What We Need, What You Get, and What is RUMBA

Currently the electronics prices for reprap, mendel, prusa, etc, based printers can range from $150 to $200 per set. I mean, especiall the parts like the main board, mega2560, the shield based on ramps and A4988 stepper drivers. We combined all in one, we improved it and made it even more affordable.

One year ago, the prices for 3D printers were high, but nowdays, in order to remain competitive, manufacturers of opensource 3D printer kits are looking for any possible way to cut the cost, but in same time they still would like to offer to their customers a good quality product, and this is not an easy task.
