Hiya I am building my first rig using a RUMBA board that I got from Ooznest UK. The board looks slightly different to the one I found on the
wiki. Compare the image of
the one on the wiki with
the one I have. The power pins next to the USB header are actually holes. There are also other pins further north, just to the left of where you put the stepper motor drivers. One of these is marked 5V, the other is not very obvious what it is. Is one of these where I attach a 5V cable so I can use ATX power? I have tried running with the jumper on USB power with a 12V supply connected but it's not moving the motor. I assume this is because the jumper is in the wrong position...Also no idea what the 3 unmarked sets of pins are just to the left of the jumper for USB versus ATX power.
Anyway, any advice would be very much appreciated!
Cheers!
