SD Card Error when trying to upload G Code File

Tried uploading a g-code file to try out my first test cut and it gave me a SD Card error. See below code from the message log.

MSG:ERR: sdmmc_card_init failed code 0x0x102]

Power everything off and then back on again do you still see the same issue?

how large a file? @bar, how much space is available?

I don’t think that it’s a space issue, I’ve gotten that error message a couple times, but I’ve always gotten it to go away with a restart. The SD card protocol is super picky about the initial values of all the pins on startup and I think there are some ways to make it confused…not sure exactly what they are.
