hi there i have 3 axis bonmet
sm60-013 motors and
sa3l04c drivers
i have them fit onto a mill that i have converted to cnc but i need to fine tune them now, i have the servofly software and also a bonmet application to upgrade the firmware but my windows 10 pc doesnt connect with the serial cable, it doesnt recognise the drivers when plugged in.

any ideas please?
ive tried a usb to serial adaptor but still no working.
