Re: Sanguish development
I've had no problems with it at 2 amps. The drivers do have to be ALL the way in to the sockets though. I've had issues with them if they are only most of the way in. These drivers are possibly more...

That looks a lot like the board I'm making. I have only 2 pwm outputs though. One for the heater and one for the bed. maybe ill add more later its still on a prototype breadboard.

I have a PSU which I have been using with my printer for about a month: [www.staples.com] So far, I had three instances of this PSU going out. 1. The firs time, I don't know what triggered it. I was...

Sounds a bit like it. That PSU has dual 12V rails internally (according to the page you linked). Each rail will have a max current rating, and if all your electronics are on the same rail, then it...

View ArticleRe: Power Supply Unit (PSU) overload?
Yes, RAMPS has 2 inputs for voltage. The 5A input runs the motors/hot end (D10)/switched fan (D9) outputs and your Arduino. The 11A input runs the heated bed (D8). The heated bed draws the most...

View ArticleRe: Power Supply Unit (PSU) overload?
Good diagram. The only thing is, while you've got 2x 12V inputs shown on the diagram, I can't tell what your PSU is putting out as this doesn't show where on your PSU those inputs go to. Are you using...

View ArticleRe: new to 3d printing, possible to build without ramps?
I'm building my electronic based on RAMPS, but for the Arduino Uno. I suppose it can work on the Duemilanove as well. My idea is to make it into small modules so it can fit with different...
