I have reflashed the firmware multiple times now. Still having the same issue. Each time I turn it on it may or may not read from SD files. Flashing, factory resetting has no impact on the issue. Yesterday for example I turned it on and it read the files, i decided i would try the calibration keychain again. It made it to the second layer, then the palette appeared to have frozen. The extruder pulled filament until the palette hit the buffer indicator, the light came on but it never fed more filament and provided the Buffer error. The filament stripped on the printers extruder gear because palette would not feed any more filament. After this failure, i power cycled the palette, and when i turned it back on it wouldnt read from SD again. I tried a dozen times during the day and nothing. In the evneing I turned it on and to my surprise it read the SD card, so i decided to print. I selected the print - it froze on initializing, a couple hours later i tried again and the print worked. Today - nothing
