Re: May have fried my ramps - strange behavior
I do not have a ramps board so this is more or less a shot in the dark. Check decopling caps c6 and c2, especially c6 because it has a polarity. If those are damaged then your power supply, if not a...

View ArticleWill this power supply work?
Hi, I am looking to use a fully modular power supply for my prusa i3 to reduce cable clutter but I'm not sure how to know if a certain supply will work. Does the following supply look ok?...
View ArticleRe: Will this power supply work?
Yes that supply will work although very likely overkill. If you want clean wiring, just remove the cover of the power supply, clip the unneeded wires, electrical tape the ends if you didnt clip them...

That psu looks very good for ATX, it can put out up to 430w @ 12v peak. It seems like a good product. It should work quite nicely as long as it does not exhibit rail droop.

Bridging it is fine. Essentially the heat bed is 1 long continuous trace. Pad 1 is in the middle of the trace and pads 2 and 3 are each end. If you only hook pads 2 or 3 but not both, then only half...

Ok. One last question I have is if I hook up the heatbed's LED can I hook up just one LED instead of 2 LEDs? Would I need to use a different size of resistor than the 1000 ohm resistor it calls for?...

Thanks for the reply, but I am not sure how the Rumba would relate to the Rambo board. There does not seem to be any silk screening involved and the vendor (Ultimachine) added a photo to the product...
View ArticleAdding On/Off Switch for Mains to RepRap
I have just built my first RepRap (Yay) and I was curious about adding a switch to be able to turn it off from the mains (US 110v). Is it is a simple as just adding a switch between the psu connection...

It should be simple. But if you're not absolutely sure, get some advice from an electrician. Note: You can buy IEC sockets (computer/kettle cord connector - called IEC C14 connector) with switches and...

@Cefiar Thank you for the response. I hadn't thought of an integrated unit. Thanks. That will work nicely.

Are you looking to power down the power supply to turn the printer "off"? Or are you looking to disconnect all power? Depending on what electronics you're using, many support turning on and off the...

I am looking to turn the printer off. All power ie. No power into the power supply. I just looked at the IEC connectors with switch and fuse and they are 10Amp fuses. Will that be enough? Thanks
