Hey @physv620, thanks for reaching out and sorry for the trouble - could you confirm that the file you uploaded to the SD card has the extension .maf and not .mcf.gcode (it needs to be .maf for Palette)? If it is, could you please try the [guide|13|troubleshooting steps in this article] and let us know if that resolves your issue?[br] [br] If you are still experiencing this issue after trying the troubleshooting steps, please let us know your shipping address and the serial number of your Palette to email@example.com - we may need to send you a new main board, with a new SD slot. Thanks for your patience!
