I run a fabkit laser with a Smoothieboard and the laser powersupply blows up, and it seems it took the USB port on the Smoothieboard with it.
The board will not recognise as USB Device anymore from PC Side. SD Card is still readable and I can still connect via Ethernet and send Commands and it seems to work fine. My Question:
Is the USB port fixable (like replacing the microcontroller mentioned here) or can I wire a Serial-> USB adapter to the serialport PINs on the board and run the board via this new/second serial port as before via USB Serial?
And in the config is a “second_usb_serial_enable” option, but I can’t see a second port on the board. What is this option for?!
