tripping breaker

[south helm]

Look i know you wanna do it yourself, but this is not a game, you are working with high voltage that can kill you very fast

Isnt there somebody who could help with the high voltage wiring?

[nova sparrow]

So, US 110V AC circuit, right?

[peak hornet]

Yes

It looks like I just need to switch the yellow and black wires

Does that sound right to you

[restive mauve]

Black to the N
Red to the L
Yellow/green to the earth ground (inverted tree)

You are lucky you didn't shock the shit out of yourself.

[slate prairie]

You are quite lucky that you are here to talk about this...
Take a close up photo of the IEC mains plug, from the front and the back.

[peak hornet]

Is there really that high a chance it would’ve started a fire or something?

[peak hornet]

Also what is IEC

[slate prairie]

You could've been a goner dear...

[slate prairie]

The mains plug

[nova sparrow]

I don't want to dogpile you with safety stuff, but you have to be careful with 1!0VAC. It is an entirely different animal than 12/24VDC.

[peak hornet]

I switched the yellow and black wires

[restive mauve]

Technically your wiring colors coming from the plug are wrong, the one that is jumped through the fuse should be black and that should go to L, it should be a white wire from the other pole of the inlet to N and the Yellow/Green from earth ground to earth ground.

[restive mauve]

That is correct

[crude plank]

Ssr is wired wrong

It's not doing anything wired like that

[peak hornet]

What do I need to change?

It powers on without catching anything on fire now btw

[south helm]

I am worried about you not a fire

[peak hornet]

😍

Sorry, I appreciate your concern @south helm, sounds like a lot could’ve gone wrong

[restive mauve]

Are you running a 24v bed heater?

[peak hornet]

I’m running the fabreeko bed heater

Wait do I have the SSR backwards

[south helm]

This thing can easily kill you, look we can help to wire it correctly, but i would really get somebody who can help in person

[peak hornet]

Everyone nearby that I know knows less about this than I do

[south helm]

One side of the ssr gets signal from the main board, other side 1 port goes to live other port to bed heater

[peak hornet]

Live meaning 24v off the PSU?

[south helm]

Polarity matter on the signal side

No

By live wire i mean a phase. I think its called live. Its the 110V

[peak hornet]

As in the wire coming off the power plug?

[south helm]

Yup, if the heater is 110v,i think fabrekoo only sells those

[peak hornet]

Well I guess the power switch

[restive mauve]

On your SSR, on of the white wires from the heater need to go to the N where the wires from your plug connect.

The other white wire from the heater stays connected to the SSR, then you need a wire from the L on the power supply to the other terminal on the same side of the SSR where both white wires are now.

[restive mauve]

If you do not understand power, messing with this line level stuff can hurt you really bad to the point of being deadly.

[peak hornet]

Fair, but so far my approach is just not touching anything while it’s plugged in

[south helm]

Do you guys have reversible wall plugs in the US? In my country i can plug it in 2 ways, so possibly change up live and neutural

[peak hornet]

Unfortunately no, they only go in one way

[south helm]

Thats fortunately😀

[peak hornet]

I just fixed it at the power supply

[nova sparrow]

Dont worry about that - it's just showing power for the pi..

[peak hornet]

And then for SSR Control will the HE0 connections work for that?

[south helm]

I would advise to find an electrician or somebody who works with printers and let them do it. You can put it together and it may work, but you won't understand how it works and tou could put yourself in danger

[nova sparrow]

Okay, so the "INPUT" side of the SSR in the diagram corresponds to the terminals labeled "3" and "4" on your SSR. These get connected to the pins that you have configured in your config files.

110VAC in the US has a Live(BLACK) wire, a neutral(WHITE) wire and a Ground(GREEN/GREEN&YELLOW/BARE COPPER) wire.

It is going to get confusing because your LIVE wire is RED inside the printer, and your NEUTRAL wire is BLACK.

The first thing that you need to do is disconnect your SSR. Take everything off of it.

[peak hornet]

Okay done

[nova sparrow]

Do you have wires installed on the HE0 terminals on your MCU?

[peak hornet]

Yes

[nova sparrow]

What are they connected to now?

[south helm]

Also please take of a photo of the breaker that popped. I think that is a gfci, but just to make sure you have one

[peak hornet]

It’s built into the wall of my apartment…

[peak hornet]

3 and 4 of the SSR

[neon basin]

also for people saying he could have died i mean its possible, but i know a lot fo electricians who get shocked by 110V all the time.

[nova sparrow]

GFCI is not required in most areas by code unless the circuit is exposed to wet weather conditions.

[peak hornet]

First time it would’ve happened to me without paying someone

[neon basin]

its possible, but for a normal, young, healthy human it shouldn't kill you.

[nova sparrow]

@peak hornet is the polarity correct? + to + and - to -?

[peak hornet]

Yes

[nova sparrow]

Cool.

[south helm]

Does matter how you get shocked, if thdre is a chance its a risk that should not be taken

[peak hornet]

Well unless the risk is low and it’s keeping you from doing something and you take precautions

[south helm]

Geez, i thought thats mandatory everywhere now

[nova sparrow]

Now, pick terminal 1 or 2 on your SSR and attach one of the white leads from the bed heater to it.

[peak hornet]

Does it matter + or -?

[nova sparrow]

No, there is no polarity here.

[peak hornet]

Cool then done

[nova sparrow]

actually, can you please post a picture of the top of your SSR without the wires blocking it? Id like to see the rating on it if its there..

(Only because I'm not familiar with that model.)

[south helm]

Its 10A

4-32vdc

I guess thats a plus so the ssr needs a heatsink aswell

[peak hornet]

I made sure to match it up with the Omron fabreeko sells

[south helm]

Wattage of the bed? 1kw?

[peak hornet]

Yes

[south helm]

You will have 9A load max, i didnt chexk the datasheet but i am sure it will. Overheat without a heatsink

My omron is 20A, datasheet says max 4A without heatsink

[nova sparrow]

I didn't forget about you - I want to look a spec up though. I don't think you want to continue with that relay.

[peak hornet]

It says 10A

[peak hornet]

Would the Omron be any better?

[south helm]

Just because it can handle 10 doesn't mean it can handle ot without cooling

I dont know this brand, so cant say, i just went with omron cause i know they sell quality. But without heatsink i am sure yours wont handle it

[peak hornet]

Okay well what can I do then or should I just say my bad and toss like $2k worth of printer + parts

[south helm]

You can have it done, but it needs more explaining if you wanna do it yourself.

[nova sparrow]

@peak hornet, this is what I'm concerned about: Solid State Relays switch load VIA one of two mechanisms. AC switching is done VIA TRIAC, where DC voltage is commonly switched by MOSFET.

[peak hornet]

Okay, I’m just gonna get this out of the way since it seems like it’s going to be an issue, I’m going to build the printer, I don’t know any electricians and I’m not willing to go find one

[nova sparrow]

This is DC-labeled SSR. If you attempt to switch AC current with a MOSFET, you will only get half-phase power passed because of the way MOSFETS switch.

[south helm]

Ohh really i didnt even check that is dc dc not dc ac

[nova sparrow]

Since this doesn't appear to be a very well-documented SSR, we need to assume that the labeling is accurate. I would not recommend continuing to wire this for AC service.

I know that you don't want to hear that when you're trying to finish your printer, but you need to source an appropriate SSR.

[south helm]

If you have time for the printer i would recommend goimg step by step eith the build read up on stuff and ask. I would help, but thats not a fast process

[peak hornet]

I don’t mind having to get proper parts but fuck me if I’m going to hire an electrician as a college student to come build a printer

[south helm]

Are you in a hurry eith the printer? Can you convert it back to original state for now?

[peak hornet]

Not currently

It was a working m1.1 like a week ago, I’m just doing all of this now because I’m doing Hydra and the electronics enclosure

[nova sparrow]

Dude, I will be happy to help you with every step of it. Hell, I'll send you an SSR if you want. Everybody learns sometime - there's nothing wrong with that.

[peak hornet]

Do you have cashapp/ Venmo? I’ll buy the SSR from you if you have an extra

[nova sparrow]

You didn't get hurt, that's what is important. Leave the rest of it behind and know that you picked up some knowledge for next time.

Message me a good shipping address.

[south helm]

Also it would be a good idea to get proper color wires aswell

[peak hornet]

True, I don’t know what the standard colors are but these wires are almost all reused from the original creality printer

[south helm]

I think somebody said white is neutural, black is live and protective earth is green yellow, but correct me if i am wrong i am on a different continent.

[nova sparrow]

Those are correct color conventions for US 110VAC.

[hot sundial]

So this thread has been active

time to read 😛

[nova sparrow]

Uh-oh. The boss is here. 😳🤣

[ionic nacelle]

Being cautious to avoid liability, docs would benefit from a 'typical' wiring diagram.

https://docs.vorondesign.com/build/electrical/

Also, seems like @peak hornet is learning here. Most importantly, his house breaker did its job and he didn't get hurt. I think the collective knowledge can guide him through this process.

[hot sundial]

Definitely something I'll write up when I'm doing the electronic enclosure docs

[ionic nacelle]

I think that would be time well spent. I think if a-a-ron is having trouble, many others will as well. Making the setup/build/config as easy as possible will definitely increase the appeal to the prospective builder.

[twilit violet]

There is loads of vids on youtube that show how an ac bed is wired up with a thermal fuse and an ssr. Do some research and definetly learn about the difference between ac current and dc current. This is stuff you dont want go at like a bull in a china shop. Take your time but pleeaaase do some research first for your own safety first and not torching your house second and damaging expensive parts or your printer third

[nova sparrow]

@peak hornet Is this one ready to mark "Solved?"

[amber mountain]

Is this picture pinned up for the build ? It would be nice to have this it looks very helpfull I think to new builders 🙂 😀

[nova sparrow]

No, Dutch will likely incorporate an SSR schematic into the docs when he’s ready..
