You Can feed it 12v just fine. I've done it for the last year.Quote

Hi, I ran into slight hitch on my 3d printer, using geeetech i3b, mega2560 and ramps 1.4. I have servo based auto bed leveling.
My printer somewhat doesn't want to print after probing all the 9 points of the bed and currently I need to power the mega by supplying a little bit of 5v through usb.
My question is, is it okay to add in another 12v to the black power input in the mega2560 and will it burn my board?
I was thinking of doing some kind of voltage divider to step down the 12v to 5v supply

If you fint it gets too hot, you just ADD a fan to it.
Some People are always overcomplicating things and believes anyone actually knows what resistive voldtage dividers are, and also believes a link to datasheet is an answer to a question.
People should realize that the majority is not THAT much into Electronics and come here because datasheets makes no sense to most people.

Yes. You can connect everything at the same time.Quote

Thank you for your reply, it is still safe if I connect the usb to my computer right with the 12v connected to the arduino mega directly from the psu?

I just use standard (here in Denmark) 0,75mm2 to 1,5mm2 wire - depending on what I have lying around. The 1,5mm2 is the standard we use for electrical lamps and such.Quote

Thank you for your reply, now I don't have to wire my arduino to usb chargers, simply from the psu, I guess it was my first post in this thread ".... voltage divider from 12v to 5v..."
One last thing, any specific wire can be used? Thinking of using just a mere 26-24ga solid core wire

Thank you in advance, so I gonna find mains wire to wire up the arduino mega directly from the psu, cause I have a wire about 0.5mm in diameter lying around, solid core what's more, but I somewhat worried that it might burn

I know, I know, we have had this before but the maturity (lack of) and available STUFF (lack of) for newer, modern controllers are the main drawback.Quote

Feeding 12V directly to the Arduino is no better than feeding it via the RAMPS. The issue is that Arduino/RAMPS provides insufficient 5V power to drive a servo, or the backlight of a graphical LCD. If you are into electronics, you can fix this by adding an external 5V regulator. If not then I suggest you ditch the ancient RAMPS electronics and get something more modern with fewer drawbacks.
