Re: RUMBA board- how to do complete setup, including firmware and wiring?

One thing a lot of people mess up including myself is the endstop configuration. Make sure to connect - and S, and leave + alone. My first wiring I connected + and - together and as you might expect the board did not boot. Arduinos have very good snort protection though so it caused no problems/frying.

The rumba is pretty stingy with its magic smoke big_smile

On closer examination it looks like a burned trace, its exposed.

Re: RUMBA board- how to do complete setup, including firmware and wiring?

Yikes. What is that going to on the board? It may or may not be causing a problem. It just depends on where it goes. Looks like it's just below the LCD controller plug?

You may be able to substitute the trace with a wire. Assuming nothing else got burned.

The real question is was that some flaw in the board or did you do something that would have caused that?

Re: RUMBA board- how to do complete setup, including firmware and wiring?

Shoot them an email, I've heard of several people having difficulties getting responses on the RRD forums. good luck. that stinks.

again where does it go on the board? it seems unlikely you did that but maybe

Re: RUMBA board- how to do complete setup, including firmware and wiring?

Best I can tell it looks like it goes to the USB controller IC, that maybe damaged too. I did contact them just now and enclosed the picture. I'll just wait and see what they say.

Re: RUMBA board- how to do complete setup, including firmware and wiring?

Looks like a +5V power line, I'm pretty sure something shorted it to ground - it may be recoverable.
Pull out the usb/standalone jumper, and use a multimeter to find where each end of the burnt trace is connected to - I'd guess one side will have a supply on it (either the 5V regulator or the 5V usb bus), and the other side will have the thing that killed it. That would narrow it down a touch... Wish I had an accurate layout file.

It might just be the 5V header or something, bung fan shorted it or something. Could also be the USB chip.

Either way, bridging it back up may not be a terrible idea, but I'd work out what the source of the problem was first...

This is a good plan and if by chance they leave you hanging than follow grob's advice.

Because the 3 banks aren't internally connected I jumped them all together to get 360 watts.
If your setup is what I am thinking you will want to connect MAIN PWR to one bank (120 watts) which is plenty to run the motors and hot end.  Then you will want to connect the remaining 2 banks (jumpered together like above photo) to the HB PWR terminals.  This setup will give you 240 watts dedicated to the bed heater only.  Of course this means you will have another set of power wires going to your board. 
Does that make sense?

Im waiting in my SD4 and have the rumba with DRV8825's...also have same psu that you are all using an e3d v6 and mk2 heatbed. My main ? is you guys were talking about connecting two banks to give 240 watts to HB in in RUMBA...since ill be using a solid state relay for mk2 whats the right way to hook all that noise up. Also is HB out needed!? Totally confused on board having both and the config im using

I know ill be running one more black and white from jumped banks for heatbed my main ? was what to do wiith them w relay and HB in and/or HB out on RUMBA

Re: RUMBA board- how to do complete setup, including firmware and wiring?

You will end up with small jumpers from MAIN PWR to HB PWR.  This will power the bed heater circuit.  The HB out wilL trigger your relay and the bed heater will get its power from 2 banks of your PSU.  If you need a diagram or picture let me know.  This will be very similar in wiring to my AC bed heater as far as the Rumba side goes.

If you could add diagram thatd be great...no rush, still waiting. I think I have it but I rather not eff it up if you have it all square and good. Thanks Ward

Re: RUMBA board- how to do complete setup, including firmware and wiring?

Don't have a rumba, but from what I see, what ever is on the other side of the board in the circle area must of shorted out to the trace that burned up. You can see where the heat has messed up the solder mask.  Bottom line, just fixing that trace may not be all that is wrong.

Re: RUMBA board- how to do complete setup, including firmware and wiring?

This should help smile

Please note that Red is typically Positive and Black is typically negative on a DC circuit.
At the very least you might want to NOT use black as the positive or put some red tape on the ends.
On an AC circuit Black is the LINE (HOT) wire and White is the Neutral wire.
Polarity of the wires on the bed heater itself doesn't matter so you can't mix those up and the same for the output side of the SSR.

If you have more questions let me know.

Beautiful thats perfect thanks a ton. I have to snag right gauge wire anyway, so ill pick up red/black...had some 14/2 SJ cord for mock reasons. But that diagram is the ticket

I recommend this board to a lot of people and I am curious as to whether or not this is a flaw or if it was something that happened on your end.

Re: RUMBA board- how to do complete setup, including firmware and wiring?

It's been almost 3 days now still no response from RRD .I should have gone with my gut instinct and bought from the other guy.

Re: RUMBA board- how to do complete setup, including firmware and wiring?

....  or not toasted your board....  tongue

I've not had any problem myself,  but then,  I've never chased support either...

I'm sure they'll get back to you..  or try BubbleRep on IRC...

But since RRD designed the Rumba,  I'd be pretty confident myself..  as opposed to "the other guy"...  and I've also bought 100's of things (quite literally)  from them with no issue. *shrug*

Re: RUMBA board- how to do complete setup, including firmware and wiring?

Have you tried to contact BubbleRep on IRC???
You have a lot of money in this board.  Unless you did something to the board that you are not sharing with the rest of us, I'd be asking RRD to make it right.

Re: RUMBA board- how to do complete setup, including firmware and wiring?

I guess i'll try that next. It's only 1am there now so i'll try later ,thanks, The picture that I posted showed the burned
trace , from the forums this seems  to be a common problem.I am not sure if something I did caused that or not.Since there are no docs with it, I very well could have hooked it up incorrectly and shorted the board.
