Running files from the SD card

[superiormaker]

I am running a file from the SD card and occasionally it will print 1 or 2 layers and then move to front of the table and stop. The table and extruders stay warm but the machine stops printing. I am starting the print with my laptop plugged in with the usb and once it starts I disconnect the usb and use my laptop elsewhere.
Is this file corrupted or what is going on ?
Thanks,
Dan

In addition to the above, I am getting this in the script. I dont know what this means ...... "CRC mismatch detected"

Any help would be appreciated!

Could be a corrupted file if it only happens on a specific file. If it happens on more than one file....after a while those little SD cards can get dodgy. Try a new one.
