Help in wiring SD card reader to RAMPS 1.4 Hello! Just got in an SD Card reader from LC Tech. I want to wire it up to my RAMPS 1.4. And test it. Googling has giving me many different approaches. I haven't found a straight forward wire pin X to pin Y. 25285_1.jpg mod_embed_images_loadimage('dc4ba2a92f375e013fb5b2d3122a8539', '/forum/thumbcache/69c/353/ae0/832/cf7/201/f26/4e9/2a7/57a/64_800x400.png', 'http://sgseller118.com/image/25285_1.jpg', 'https://reprap.org/forum/addon.php?219,module=embed_images,check_scaling=1,url=http%3A%2F%2Fsgseller118.com%2Fimage%2F25285_1.jpg', '', 245432, 800, 400, 'Loading image ...', false); So can anyone tell me to which pins on the Ramps 1.4 do I connect?

Hello I use the another sd board
Whene test the system read the sd Card and show the gcode but it cant Open it
ErorSays Says = Open failed file:(name gcode)

What size is the partition you are using and how is the card formatted?

Could you upload the gcode so I can check if there is maybe an error in the gcode?]]> Ohmarinus RAMPS Electronics Wed, 03 Jul 2019 06:17:10 -0400 https://reprap.org/forum/read.php?219,245432,855889#msg-855889 Re: Help in wiring SD card reader to RAMPS 1.4 https://reprap.org/forum/read.php?219,245432,855889#msg-855889 Whene test the system read the sd Card and show the gcode but it cant Open it

Final question, there are ground pins on the card.(SEE ABOVE PHOTO) Do I ignore the ground pin next to the 3.3v pin? Should I jumper both grounds together?

Thanks]]> disneytoy RAMPS Electronics Wed, 18 Sep 2013 00:49:28 -0400 https://reprap.org/forum/read.php?219,245432,246033#msg-246033 Re: Help in wiring SD card reader to RAMPS 1.4 https://reprap.org/forum/read.php?219,245432,246033#msg-246033 waitaki RAMPS Electronics Tue, 17 Sep 2013 07:01:55 -0400 https://reprap.org/forum/read.php?219,245432,245926#msg-245926 Re: Help in wiring SD card reader to RAMPS 1.4 https://reprap.org/forum/read.php?219,245432,245926#msg-245926 disneytoy RAMPS Electronics Mon, 16 Sep 2013 22:45:04 -0400 https://reprap.org/forum/read.php?219,245432,245825#msg-245825 Re: Help in wiring SD card reader to RAMPS 1.4 https://reprap.org/forum/read.php?219,245432,245825#msg-245825
DON'T connect the 3.3V to the ramps. There is a 3.3V regulator on your board (the AMS1117), so the 3.3V is an output, not an input, and you don't want to connect 2 similar power supplies to each other.

The grounds are all connected together on the ramps board, you only need to connect to one, but more than that wouldn't break anything.

You might want to allow the firmware to detect whether an sd card is inserted. If so, you'll need to solder a wire carefully to the sd card socket directly (it's not broken out on your board). Look here for details: [tommyc-reprap.blogspot.co.uk] (search the page for "SDCARDDETECT Hack"

CS can be connected to a few different pins, check your firmware. In marlin this info is in pins.h, listed as "SDSS". If you do the card detection thing I just said, you need to set SDCARDDETECT to something, just find an available pin.

I just formatted the card as FAT, and put some gcode files on it (if you're trying with real reprap firmware, put some .gcode files on there as I don't know if it shows .txt files for example)

hope this helps]]> james glanville RAMPS Electronics Mon, 16 Sep 2013 12:53:21 -0400 https://reprap.org/forum/read.php?219,245432,245437#msg-245437 Re: Help in wiring SD card reader to RAMPS 1.4 https://reprap.org/forum/read.php?219,245432,245437#msg-245437
Update: got most of the pins wired. Question, there are two ground pins labeled on the SD reader? But on the RAMPS Aux 3 there is 1 GRND pin available. Do both need to me used? Just one?

I'm not a electronics expert. Is there a different ground circuit for 3.3v and 5v?

And for future reference, If anyone is doing this, I found a script to test if the SD card is working properly. Haven't tried it yet.

Check this:

Just wire up the pins as labeled, MISO to MISO, MOSI to MOSI, etc. I believe that CS needs to connect to pin D53. You should be able to leave 3.3V disconnected.]]> NewPerfection RAMPS Electronics Sun, 15 Sep 2013 00:12:21 -0400 https://reprap.org/forum/read.php?219,245432,245432#msg-245432 Help in wiring SD card reader to RAMPS 1.4 https://reprap.org/forum/read.php?219,245432,245432#msg-245432

Googling has giving me many different approaches. I haven't found a straight forward wire pin X to pin Y.



So can anyone tell me to which pins on the
Ramps 1.4 do I connect?

Then is there s script I can load to test the SD reader? Like write a text file, then I can see if I can read it on the PC? Also, I remember reading the SD card must be formatted a certain way.

Thanks

I'm sure it is easy, but so far I haven't seen clear directions.

Thanks
