After waiting 3 months for a X7 spindle driver board from Syil China the spindle still wont run

I can't see any loose wires

Syil asked me to check the voltage from the controller to the board when the spindle is activated and I'm getting 5 volts

I haven't been able to use this mill since I got it 3 months ago because the spindle wasn't working and are getting desperate to get it going

I would appreciate any help

Thanks,
