SD Card Crashed?



  • I relocated my filament spool from the top of my Ender 3 to attach to the left side of the base by the Z axis motor (less weight up top and filament aligned with extruder). During the beginning part of a print last night, homing procedure, the print head was lowering and my filament spool got trapped underneath the Z motor. I tried to use the control panel to pause the print but it wouldn’t stop so I switched the power off. Since then, the control panel is blank and the SD Card says it needs to be formatted if I plug it into my computer.

    Did the SD Card crash because I reset power? I’ve done this when setting up the printer but not had this issue, is there a reason for it happening this time? Is it possible to send emergency stop from the control panel if it had the menu option? Is there anything I can do to resolve this or do I have to start over (I’ve no recent backup since adding z probe)?

    UPDATE: I've reformatted the SD Card and am in process of setting up macros, adjusting z probe offset, mesh bed leveling, etc. This time I'll be making a backup but would be nice to understand why this happened to prevent it in the future for somebody else.



  • what version of the firmware are you running?



  • I'm using firmware file Duet2Firmware-2.02a.



  • I'd probably use this tool to do a full format of the card before I trust it again.

    It's possible it was in the middle of a write when the power was killed. Or could be the card was just failing to begin with.

    It's actually a fairly common problem on RaspberryPis. Some people switch to using USB storage devices instead of the SD card for the boot drive.

    Thanks, I'll backup the files, format as suggested, and copy the files back.
