Hi , Iv just put together the original DIY kit , was hoping to print something but im having trouble getting it to work . Its brand new and haven't used it even once yet. So after getting it all together I installed drivers onto PC , downloaded CURA and connected the ultimaker to PC via USB. I let it install firmware Merlin 250000 , alright so I did that. It allowed me to pass all the checks like heating and temp sensor , and the z stage moved up and down ok that all works but something is screwed up , because while its plugged into the PC VIA USB only it works fine as in the screen on the ulticontroller doesn't blink , but as soon as I turn on the power the ulticontroller screen flashes and the z stage motor and feeder motor make weird intermittent sounds its like the tempo of the intermittent noise is synced with the flashing on the screen and also even the blue led on the print head also flashes and on the motherboard the led numbered 06 flashes also synced to the tempo of the flashing of the ulticontroller and blue led on printhead. Now the strange thing is as soon as I remove the power and leave just the USB plugged in it appears normal, no flashing of leds and no sounds, but as soon as I turn on the power again it starts making noise and flashes. Now also If I just leave the power on without the USB plugged in all the info on the ulticontroller disappears and the screen just flashes and motors make sounds.
I have included a video of the problem and hope someone out there can help me use my new ultimaker , I checked everything many times to make sure I didn't make a mistake and im sure iv got it all hooked up correctly so please help me if you can.
