RUMBA board SD card Hi guys, At this moment I'm using a g3d RAMPS 1.4 board. As an upgrade I want to use a RUMBA board bought from ebay. I get everything working except for the SD card. At the moment I plug in a SD card the board freezes directly. With my RAMPS 1.4 board the lcd display always turns off and on when I plug in a SD card. I also made a video about it: https://www.youtube.com/watch?v=sTrFDSzKi48 Yes I know the wiring is horrible at the moment 8-) Any suggestions? For your information, I switched the exp 1 and 2 plugs and turned them 180 degrees. The software used on the RUMBA board is the latest marlin version. https://reprap.org/forum/read.php?13,729265,729265#msg-729265 Sun, 17 May 2026 17:26:58 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?13,729265,742475#msg-742475 Re: RUMBA board SD card https://reprap.org/forum/read.php?13,729265,742475#msg-742475 notepad-plus-plus.org]]]> kd6hq Controllers Thu, 26 Jan 2017 11:10:22 -0500 https://reprap.org/forum/read.php?13,729265,742359#msg-742359 Re: RUMBA board SD card https://reprap.org/forum/read.php?13,729265,742359#msg-742359 I just received my Rumba board and want to run a adapted version of Ramps-test software on it before diving into Marlin setup.

The pins_Rumba file attached from kd6hq above is pretty much unreadable, as is the configuration.h file.
Would you be so kind and tell me, what editor to use to read out the pin numbers?]]> o_lampe Controllers Thu, 26 Jan 2017 06:41:48 -0500 https://reprap.org/forum/read.php?13,729265,738298#msg-738298 Re: RUMBA board SD card https://reprap.org/forum/read.php?13,729265,738298#msg-738298 Jan-Willem Controllers Fri, 13 Jan 2017 04:08:43 -0500 https://reprap.org/forum/read.php?13,729265,737925#msg-737925 Re: RUMBA board SD card https://reprap.org/forum/read.php?13,729265,737925#msg-737925 It could be that shielding would help but I am not using any and the display seem fine to me.

On my other printer - RAMPS board - same display, same vendor, the display works fine.
The other printer has no shielding.

It would be pretty cool if it works how I want.

Does Marlin allow you to specify different steps/mm for each extruder? Then it will work.

Can you overwrite these values with Gcode( M92 Exxxx:xxxx ? ) to change mixing ratio while printing?]]> o_lampe Controllers Thu, 05 Jan 2017 03:42:52 -0500 https://reprap.org/forum/read.php?13,729265,735587#msg-735587 Re: RUMBA board SD card https://reprap.org/forum/read.php?13,729265,735587#msg-735587 Jan-Willem Controllers Wed, 04 Jan 2017 12:36:32 -0500 https://reprap.org/forum/read.php?13,729265,735512#msg-735512 Re: RUMBA board SD card https://reprap.org/forum/read.php?13,729265,735512#msg-735512 If you get it to work you should be able to come up with some really interesting printed objects.]]> kd6hq Controllers Wed, 04 Jan 2017 07:36:38 -0500 https://reprap.org/forum/read.php?13,729265,735499#msg-735499 Re: RUMBA board SD card https://reprap.org/forum/read.php?13,729265,735499#msg-735499 Jan-Willem Controllers Wed, 04 Jan 2017 07:07:39 -0500 https://reprap.org/forum/read.php?13,729265,735487#msg-735487 Re: RUMBA board SD card https://reprap.org/forum/read.php?13,729265,735487#msg-735487
When you do get to the DRV8825, be aware that they are rotated 180 degrees from the A4988. Just like the Ribbon cables on the display.
See [forums.reprap.org]

Notice that the voltage adjustment pot is at the top left in the picture. While on the A4988 the pot is at the bottom right-center.

They do work and will give you 1/ 32 stepping.]]> kd6hq Controllers Wed, 04 Jan 2017 06:50:04 -0500 https://reprap.org/forum/read.php?13,729265,735477#msg-735477 Re: RUMBA board SD card https://reprap.org/forum/read.php?13,729265,735477#msg-735477 Jan-Willem Controllers Wed, 04 Jan 2017 06:03:03 -0500 https://reprap.org/forum/read.php?13,729265,735396#msg-735396 Re: RUMBA board SD card https://reprap.org/forum/read.php?13,729265,735396#msg-735396

I have received a lot of help along the way.
Be advised I am using Marlin 1.1.0-RC7

I will be using a Diamond hot end with this printer so the extruder section is setup for it.
You will need to change it if you are not using one.
I do not have this printer fully operational yet so I have not verified the operation of the hot end yet. There may be more code to change.

I will include the RUMBA pins file as it has been changed to work with the Diamond hot end also. If you are not using the Diamond hot end do not use the pins file.

Line # 159 defines a mixing_extruder (Diamond)

I am building a Core XYZ printer, so that part has been activated also.
That is Line # 385

You may want to change Line # 129, it is the custom message sent to the information screen showing "CoreXY 12-18-16C" on the start up screen.

I think that is all but check the files, if you are using a Diamond - it could be that yours is better setup than mine is.]]> kd6hq Controllers Tue, 03 Jan 2017 17:31:35 -0500 https://reprap.org/forum/read.php?13,729265,735367#msg-735367 Re: RUMBA board SD card https://reprap.org/forum/read.php?13,729265,735367#msg-735367 Jan-Willem Controllers Tue, 03 Jan 2017 16:45:41 -0500 https://reprap.org/forum/read.php?13,729265,735360#msg-735360 Re: RUMBA board SD card https://reprap.org/forum/read.php?13,729265,735360#msg-735360
Apparently pin #53 is the correct one.

Have you ever heard the term "Operator Error", well I have and I've done it more than once.

I am using Windows 10 on the computer.
When I format the SD card I have these options.
NTFS
Fat32
Fat
exFat- never heard of this one.

So I reformatted each one and copied a G-code SD card file over each time. I always used the same file.

The NTFS format was not recognized by either the RAMPS 1.4 or RUMBA board.
The Fat32 format was recognized by both the RAMPS and RUMBA board, but the file was not.
The Fat format was recognized by both the RAMPS and RUMBA board, but the file was not.
I did not even try the exFat format, since the other two worked.

Ok, I switched to the SD card menu I did not see the file that I copied over. So I took the card out and checked it and it was there just like I thought.
The only thing the SD card menu showed was
Main
(Rectangle) ..

The it occured to me, just because if recognized the card did not mean it read the card.
So I moved down to (Rectangle) .. and clicked on it, the file appeared. So if you don't see the file right away you need to select the sub directory so that the firmware will read the file list.
I then turned the printer off and let it set for a couple of minutes and then turned it on again. I left the SD card inserted. When the printer powered up to the basic info screen there was no "Card inserted" notice, I went ahead and clicked on the info screen and it showed "Print from SD" in the option list. When I thought about it, it made since.
Since I did not "inserted" the card, it did not show the message.

I only have the one SD card for now. Apparently it remembers the list until you tell it to read a new list by going thru the read procedure. So if you change SD cards or add / subtract files the card needs to be read again.

LCD I am using on both.

Did you remember to cross the ribbon cables so that so that EXP1 on the RUMBA board goes to EXP2 on the display and EXP2 to EXP1?
Of course I did. In the end I tried every possibility but no succes.

If so then try plugging in the display board to a RAMPS board. You will need the adapter for the RAMPS board.
At least that way if it works then you know that there is something going on with the RUMBA board.
I'll try it on my ramps board. Yes I have the adapter.

I have also heard that not all Full Graphics boards will work with just USB power.
Mine dose but then when I turn on the power supply it gets noticeably brighter.
Thanks, I'll try on power supply

For basic function, I have both the RAMPS and RUMBA board using a Full Graphics boards. However on the RUMBA board the SD card dose not work.

It appears that the firmware for both boards uses pin # 53 to enable the SD card. But the RUMBA will not enable the SD card.

I am waiting for parts for the new printer so I will start playing around some more and keep you posted.

yeah it is really strange. And it seems that not a lot of people are using the board so the support is not that great. keep me updated!]]> Jan-Willem Controllers Tue, 03 Jan 2017 07:21:39 -0500 https://reprap.org/forum/read.php?13,729265,735137#msg-735137 Re: RUMBA board SD card https://reprap.org/forum/read.php?13,729265,735137#msg-735137

When I plug in the full graphic controller and apply usb power to the rumba board windows doesn't recognize the board anymore. So this seems to be a hardware issue as well.. off coarse I included the u8glib library in the main page.. sometimes I get 4 white squares on the board with some extra random pixels and some pixels missing in the squares but that's it.]]> Jan-Willem Controllers Tue, 03 Jan 2017 03:43:32 -0500 https://reprap.org/forum/read.php?13,729265,735046#msg-735046 Re: RUMBA board SD card https://reprap.org/forum/read.php?13,729265,735046#msg-735046 kd6hq Controllers Mon, 02 Jan 2017 19:05:18 -0500 https://reprap.org/forum/read.php?13,729265,734936#msg-734936 Re: RUMBA board SD card https://reprap.org/forum/read.php?13,729265,734936#msg-734936 Jan-Willem Controllers Mon, 02 Jan 2017 12:25:45 -0500 https://reprap.org/forum/read.php?13,729265,730301#msg-730301 Re: RUMBA board SD card https://reprap.org/forum/read.php?13,729265,730301#msg-730301 Jan-Willem Controllers Tue, 13 Dec 2016 12:19:21 -0500 https://reprap.org/forum/read.php?13,729265,730298#msg-730298 Re: RUMBA board SD card https://reprap.org/forum/read.php?13,729265,730298#msg-730298 thanks]]> kd6hq Controllers Tue, 13 Dec 2016 12:13:49 -0500 https://reprap.org/forum/read.php?13,729265,730091#msg-730091 Re: RUMBA board SD card https://reprap.org/forum/read.php?13,729265,730091#msg-730091 g3d:

rumba:


due to the difference in pinout it forces activates a reset loop.

The full graphic display pinout looks much more compatible:


So I ordered that display and hopefully it will work.
