Welcome to the SeeMeCNC Community

I needed AC power to feed to 220VAC heat bed and the DC +5, +12 and GND to feed my RAMPS1.4 and limit switches i came up a solution.

Thanks for posting these, I am sure some of our users will be able to use these.

I realize you're probably making use of what you have handy, but from the safety standpoint it's scary. A 5-year-old version of me would almost certainly stick the wrong cord in the wrong socket. I hope you don't have small kids in the house.

Eric you are correct about the small kids. Those exposed metal pins are at lethal voltages and anyone sticking their fingers in one of the sockets could kill.

It's not so much the exposed pins as it is the mis-match of voltages using the same connector. Mix the cables, meet magic smoke (and possibly even its cousin illusionary fire).

Guys why do you think that the "Those exposed metal pins are at lethal voltages"? Think-out-of-the box man... Have you ever seen the other endi.e. plug, if i say that the live voltage is in the plug then do you think these exposed metal pins will still be at higher voltage?

You are right .... This can be avoided by SMART TAGGING and color code... Thats all...

Woah there sonny! You're talking about personal responsibility and we just can't have that here! You must be from one of those weird countries where the gov't doesn't try to interfere like a nagging mother-in-law protect you from your tender, stupid, self.

(Feel sorry for those poor folks in the UK. They're one wobbly step away from having a national flag that's reflective silver stripes upon a field of safety yellow!)

Khalid, as long as you know what you're doing, good on ya.

You have to admit though, even for the most staunch "Hey ya'll, watch this!" types among us [raises hand], a pair of male IEC connectors at different voltages gives us pause.

This is why I would redesign it with one IEC, and one standard UK wall socket (I live in the US), so that that way the can't be plugged together. Not that I care about the exposed voltages on the IEC, but two of them is just asking for trouble. Now, you say the other end is your source. That's goodness. But I would still be careful, and make the plugs for different voltages physically incompatible. It won't be a cure all, but it will prevent most issues (See the Russian assembly tech who installed a keyed assembly upside-down inside a rocket, using a hammer). This way you can potentially have others work on the printer without killing it. This is always my goal, unfortunately, my printer is a mess wiring wise right now, since I have a few lines routed externally up the printer, and in one case, a thermistor lead has somehow warped itself into a tangle in the middle of a stepper cable.

Still, a pretty useful box you got there, and not to shabby looking.
