Unbrick STM32 Arm Processor using ST-Link CNC, 3D Printer, Novusun NVEM EC300 EC500 SKR Mach3

I had to buy one of these USB ST-Link to recovery some firmware. The board I'm recoverying is unique. It does not have a USB port or SD card to flash BIN files. Every day I seem more and more equipment with these ARM processors. Pretty amazing devices.
