I received my order of a second controller this afternoon, and just shut my SO3XXL down, pulled the plugs from my existing CMB and insert them in the new CMB (both v2.4d) to test it before continuing with the project I bought it for, and on starting Carbide Motion and clicking connect I get the following:
Cannot Open Port for cutter
GRBL Error: Serial Port: Not Open Error
GRBL Error: Serial Port: Device Not Found Error
then back to the connect screen, and back though the above if I initiate a connection...
Windows audibly recognizes when I plug in or un-plug the usb cable.
with the power off, manually Moving any of the steppers makes the right lights go on.
The Steppers make the appropriate buzzing when the power is turned on.
I plugged in the original board(both are v2.4d) and everything runs as it should...
I plugged it in to test it before flashing it for EstlCAM.
Other than not finding the USB port, and what comes next, everything I tested has the same responses from one board to the other.
Maybe this board was not flashed for GRBL and Carbide Motion is simply not finding the port setup in the firmware? I did specify that I would be flashing it for ESTLCam when I ordered it, but there were no notes with it. Ideas, suspensions, etc...
