The screen read "buffer error" and it did not give me the option for restart or continue print.... so I lost a days worth of a very large print. I am using a USB stick to store the Gcode program on, no WIFI etc.. I used prusa slicer 2.9.4 to generate the Gcode program. The printers firmware is 6.2.6

Does anyone know what's going on here? This printer is less than a week old. I don't dare try another large print right now.
