SD card

[Galax97]

Hello. I have a new Einsy RAMBo 1.0a motherboard and I configure Marlin v1.1.9 firmware on this board. I have a full graphic smart controller LCD. After changing configuration.h, I managed to set up the LCD but could not read the SD card. When I insert the SD card into the slot, the LCD writes "The card inserted" but I see the "No SD card" in the menu and I do not see the files on the card. The SD card is OK. My computer see the SD card and the files on the card. I've formatted the card on FAT32. Can you help me please?

I have the same issue with Marlin v1.1.9. Serial Console prints: echo:SD init fail once when I insert the card after startup and twice when booting up with a inserted SD card.

My setup:

• MKS Gen v1.4
• RepRapDiscount Smart Controller
• TMC2130 Driver with SPI
• Anycubic Kossel Linear Plus (Delta)

There seems to be no Hardware defect on the LCD-Smart Controller because I already switched it with one I use in my Prusa i3, where the same SD cards do not have issues.

My Marlin config can be found here: https://github.com/thetechnick/Marlin/tree/anycubic-kossel-mksgen-tmc2130

@Galax97 I just found my issue by reading this: https://github.com/MarlinFirmware/Marlin/issues/11312#issuecomment-408145106

In my case using the TMC2130 drivers with SPI enabled will use the same pins (53 and 49) as the SD card communication. When using the BOARD_MKS_GEN_L config instead of BOARD_MKS_GEN_13 the pins 59 and 63 will be used enabling the SD card reader to work on 53 and 49.

There is also a comment in the file indicating a issue with the PIN selection:

// CS Pins wired to avoid conflict with the LCD

I am developing a new RAMPS 1.7 board, and I am also having issues with reading the SD card. For my testing, I am currently using the 4x20 text LCD, ReprapDiscount Smart Controller LCD + SD-card system. In Marlin configuration.h this is known as the REPRAP_DISCOUNT_SMART_CONTROLLER

I have made a small Arduino sketch, that directly adresses the SD-card, and does a "list filenames" from the card. Using this test sketch I can read the SD-card on my setup, so this tells me that the hardware works. The test sketch can be found here: https://github.com/MrAlvin/RAMPS_1.7/tree/master/Arduino%20test%20sketches/test%20ports-3-4-LCD/SD_listfiles

But I can not get Marlin 2.0 (bugfix) to read the SD-card, so I will continue my research into why that might be.

[Edit] sept 4 - 2018 My problem was with Due, and RAMPS 1.7 board and bugfix-2.0 - but I have got it resolved now. I will try to figure out how to make a pull request, so bugfix-2.0 will work with my new RAMPS 1.7 board [/Edit]

hmmm.... after making very sure that the SDcard was placed just right in the card reader (I checked it was the case by using the SD_listfiles test sketch), then Marlin 1.1.9 was able to read the file list, and Repetier Host 2.0.5 reports all files with last name .gco [Edit] This test was made with a Mega, and my new RAMPS 1.7 shield. [/Edit]

And while avoiding moving the SD-card, then I can also get bugfix-2.0 to read the SD-card. I am happy :-)

Do you (@thetechnick or @Galax97 ) still have problems about reading your SD-cards?

@MrAlvin I do not have any issues, after changing the pin assignment, but my issue maybe completely unrelated to @Galax97 issue.

Some people have worked around sluggish SD card readers by putting this at the end of the setup() function:

#if ENABLED(SDSUPPORT)
  if (!card.cardOK) card.initsd();
#endif

@Galax97 problem solved?

@thinkyhead i think we can close this one
