My cnc router was working well, when I started getting error messages. Smoothstepper is used.
Error message is:
Error returned from USB function FT_Write
Error: FTDI USB driver error
ERROR= FT_INVALID_HANDLE
Bytes requested 64
Bytes written 26
Any suggestions for fixing this?
Red led remains lit on smooth stepper
Thanks,
Jim

You have a ground loop issue on the 5v supply to the USS, have a look at the info on the warp9 website and forum, plus ask on the forum as it is better supported by the manufacturer
