Hi,
I recently updated Marlin Sanguino firmware on my Melzi motherboard for my 3d printer, and now I want to print.
Problem: The port COM3 is not being recognized by the pronterface. I went into device manager, and COM3 was under 'Other devices' and i made sure that this was recognized as a Port. Now, when I try to connect the printer to pronterface, this is the error I get:
Serial error: Could not open port COM3: [ERROR 5]: Access is denied.
Any help with what might be going on?
