Hello!

Testfirmware is downloaded reprap/wiki site.

Ok, i trye that baudrate-thing(115200baud works), and no i can read serial monitor on testfirmware, but LEDs on the boards still doesn´t blink correctly.

Then i load marlin firmware back, and board doesn´t communicate correctly on serial monitor.

More pictures about it.. Good quality, some dry joints and cross soldered components. Are there a short circuit or is that R1 and C12 contact ok? And that SD-reader....

At last i can get my 3D printer under the work, and first i upload test firmware but this board don't work. It takes testfirmware in ok, but it only say beeb sometimes(and TX & DBG led flashes) and don´t communicate correctly. Picture will explain more about that.

So what we to about it?

regards J ...
