Just reporting a small issue
I've configured my computer to deliver 5v on USB3 ports also when switched off.
When the computer is off, for some reason the USB3 ports delivers only 3.16V. The power led on the AMC is On but nothing on the screen, and what is wired, is that the motors are spinning regardless the sensor position.
One could maybe limit the AMC NOT to run at all, when it can not deliver the correct voltage. luckily my off-line speed was set up to 5 when the computer shut down, I had time to avoid the desaster :-)
a bit confusing.
cheers

The watchdog for low voltage on the amc1280usb is set to 2.4v, this it to avoid unnecessary resets during use. You can use a powered USB HUB to keep it always on.
Thanks Thanos

cheers.
