Spindle not running - Need Help

[Lumiyo Ben]

Hi MYCNC community,

Im having trouble with getting my spindle to spin up. I don't really have any knowledge of how my machine works and would love some help on this.

Ive attached a couple of pictures of where i think the issue is being caused.

There is a flashing red light on D17 on one of the boards which wasn't showing yesterday.

This light stops flashing if the usb lead is removed.

Thanks for reading.

Any advise would be amazing

Cheers

Ben
