Hello...I need some help about electronic on prusa i2.
Just built this machine but there's something wrong with some electronic.
Have a problem with arduino and ramps 1.4...
First time I connected everything like it was said into build manual(all jumpers inserted to set 1/16step, drivers 4988 inserted to have a trimpots on the right-looking lcd pins, cutted 12V yellow/black wires on atx psupply followed pictures in manual. And NOTHING HAPPENED... I gave it power and nothing...
So, i disconnect complete ramps board and connect just the arduino into pc... and it started installing into windows.
After that I tried again the same thing with the ramps board connected a again have a failure
And decided to remove drivers out and try again with both boards connected... end the boards successfully comunicate with pc.
How to know whats wrong with my electronic? should I change drivers?
Thanks a lot
