I get an “SD Init Fail” error whenever I insert an SD card into my TAZ 6. Printing works well with USB, but I need to switch to printing from an SD card now that computers in the makerspace are set to auto logout after a short period of inactivity and to generally free up the computers.
7 different SD cards (that work in other devices) formatted using FAT32 w/ MBR from 2 GB to 16 GB capacity. Also tried making an 8 GB partition on a 16 GB card. I even tried inserting SD cards not 100% of the way pushed in as was mentioned a few places.
Bought a new RepRapDiscount Full Graphic Smart Controller and plugged it in but get the same result. So I don’t think the card reader itself is faulty.
Tested the continuity of the cabling that goes from the controller to the RAMBo and re-seated the connectors.
The TAZ 6 does recognize when the media is removed.
CuraLE 3.6.37 on an iMac MacOS 12.2.1
Firmware Marlin 188.8.131.52.13 installed via CuraLE.
I couldn’t read an SD card when the firmware was at its previous version (1.19.34??) either. Using the old firmware, the main screen showed “Card Inserted”, but the the card couldn’t be read and when I scrolled down in the menus the last menu option said “No SD Card”. This 3D printer predates me in this makerspace so I don’t know when the last time the SD card reader worked, if ever.
The SD card seems to seat well in the reader that was originally in the TAZ 6 and also in the reader on the new controller that I bought. The original SD card that came with the machine is long gone, but I ordered a new card to test and will update if this post if it works.
Do you think that it would be worth it for me to change firmware configuration settings? On various forums, I see people try changing settings like SD_SPI_SPEED, SDCARD_CONNECTION, and SPI pin settings like SDSS. I’d assume that the Lulzbot official firmware has these settings correct, but then again, my SD card isn’t working, so it might be worth a try.
