Having a problem I have not encounter before.

I am carving a military rank plaque with keyholes on the back. Load the back keyholes cut just fine, flip the board and start carving the plaque.

About 4-5 percent into the carving I get an error message to reformat the card and reload the project.
I have reformatted the card and reloaded the project and the same error occurs.

I changed cards - same error

I even actually even started all over with project saved to a different file name and get the same error.

I think I have the problem lies in one of 2 areas - either the Power supply or the controller.

No issues with my other C model machines. Just this one.
