RUMBA board- how to do complete setup, including firmware and wiring? (Page 3 of 10)

60mm fan does the job though.

Anyway, my setup on the closest to hand Ord :

So I got my Rumba today and have been taking (far too much) time mounting, cleaning up the wires in back, etc.

I most likely will not have time to deal with the firmware fun-time tonight, but I had a couple questions before I progress:
*Whenever I had a Printrboard or Sang hooked to USB, even without power to the board, a light always came on...this is not the case right now. I have the USB plugged in ready for the update, but no light. I take it this is nothing to worry about?

*The old SD connectors can fit (VERY tight fit), but I have the steppers off. Can someone confirm that this is possible to not have to splice into existing wires?

*Finally - THERMISTORS GALORE! What application would one need six thermistors for a Rumba? Also, I can only assume that these are different thermistor types/sizes than used for the E3D?

Thanks for your previous posts, BTW.

Awesome...thanks!

Soooooo they are the same that come with the E3D? They look larger like the stock SD ones.

Sorry...the 4pin connectors for the motors. While organizing my wires and getting rid of excess slack, I plugged in a couple spots to see what I could run with stock plugs and what I couldn't. So far I noticed the wires for the lights are too short, but that is irrelevant at the moment. So the original connectors are tight against one another.

I appreciate the offer! I will keep it in mind. But I think I should be fine with all the wires that came with the Rumba.

So I downloaded the latest Marlin and fortunately I scrolled through everything and here is what I found:

*Changed board from 62 (Sang 1.2>) to 80 (Rumba)
*Scrolled further and found in line 22 I was at an SD3...changed that to 2
*TEMP_SENSOR_0 1 at first...Changed that to 6 since I have the E3D as well as line 161 MAXTEMP to 310

That is it, right?
She will not compile at the moment so I wanted to make sure I got this all together.

Yup. Only on the motor connectors from what I've noticed.

Trying to get past the firmware before messing with the plugs...realized that will be simple between the provided wires and the photos you posted....thanks!

You were right that I did not download the driver. Seems I missed that link. But I got that installed, and it still will not compile...tried about 20 times now. Took me a long time with the Printrboard as well, but the Printrboard is garbage and I think it may be my computer at this point.

Thoughts?

Thanks for the offer!
And yeah, the thermistors did appear much larger than the ones used for the E3D (semetec?). I'm just trying to find what type they are so I could find a use for them. Couldn't find the info on RepRapDiscount or with my Googlefu.

I am fairly certain my problem is stemmed from the location of the Marlin directory. I have Arduino in program files, and Marlin is just sitting on the desktop. If I recall correctly, some/all files need to be saved in a certain location?
Reason I think this is because once I save, close Arduino, and open it back up straight from the Marlin configuration.h file, none of the changes saved. By changing the settings again, and hitting Save As, it displays a folder I am unfamiliar with. So I need to find how to properly save the Marlin files. Hope to get it flashed and wired up tonight.

Yup!
wardjr sent me a screenshot of his directory and it comfirmed my theory. I'm at work, so I won't be able to test it until early this evening.

Look at your device manager when you plug it in.  What comes up?

I don't have to click or hold reset or do anything else to upload firmware.  Just click upload and it gets done.  Try that.

Question - is it ok to run both the main power and bed power off of the same bussed 360W power supply or should I de-bus my power supply and only use 120W for the main and 240 for the bed?

Oh yeah - my sanguinololu wiring connectors definitely don't play well with the rumba - doing a franken-wiring setup for now until I put together something better for the long haul.

You and I are brothers on the same mission tonight.

I need some help - I have the taurino driver but when I try to download the usb driver I keep getting "failed - server problem".  Would you be willing to email me the zip file?  I'll PM you with my email address.

Thanks,
Jake

The zip file I sent is the same as wardjr's post. It is the sixth post on the first page of the thread. Just make sure you scroll through the entire configuration.h file. Get those settings right so everything runs smooth and safe!

I am more than happy to help where I can
