Topic: Power Supply Blew

Good day Soliforum.

Here is a another interesting solidoodle problem.
I was gladly printing away today, then suddenly, "BANG".
The horror of burnt silicon engulfed my panic strickend nostrils.

I measured the 12V output from the power supply, and alas, no voltage.
I proceeded to tear open the power supply to inspect the source of the problem.

Just as I thought. Blown mosfet. dead short across all pins.
Cause: Overheat + china parts.

I will be making a case with solidoodle to have the power supply replaced, as the printer is not even 6 months old.

If they don't replace it, PM me - I might be upgrading mine, and could send you my original one.

Thanks Elmoret. Im in South Africa thou, and need this printer running by tomorrow. I think i might just find a old pc psu and tap into the 12V rail.

Whoops! Probably not worth it then.

You need something capable of 10A on +12v. Remember that old PC PSUs need load on their 3.3v and 5v rails - a 5 ohm, 5w resistor on each should be enough.

Yeah i saw that.

This is the datasheet for the part that blew:http://www.eet-china.com/STATIC/PDF/200903/sl-3.pdf
This is the datasheet for the part in going to replace it with: http://www.mantech.co.za/Datasheets/Pro … 0N60C3.pdf

Hope it works, gonna inspect for any other damage. SOLIDOODLE STILL SEND ME A NEW ONE, THIS IS BS!
