M3 Dead

[cdb0ewm]

I hadn't used my M3 for a month or so but when I tried to fire it up today it won't move to any X, Y, or Z command. Here's what I checked

• Made sure connect to right com port
  
• Verified that baud at 115200
  
• GBRL selected
  
• Power supply is powering board/fan
• Rebooted computer
  

When I power up the power supply I hear a clunk but that's it.

Any HELP is appreciated

There should be another clunk when the USB cable is plugged into the PC from the control.
What software are you using? If it's powered up you would have torque on the motors. Did you verify the com port in Win10 Device Manager?
