I am using a prusa I3 printer with the acrylic frame. I was moving my y-axis end stop to a new holder i had just printed and i think i accidentally caused a short (yes i know i should have disconnected the power to the printer) because now my computer doesn't recognize the board. My computer doesn't even register that something has been connected to it. when i try to run the arduino file to connect to the printer i get this error message:
Arduino: 1.6.7 (Windows 7), Board: "Arduino/Genuino Mega or Mega 2560, ATmega2560 (Mega 2560)"
Sketch uses 87,342 bytes (34%) of program storage space. Maximum is 253,952 bytes.
Global variables use 3,648 bytes (44%) of dynamic memory, leaving 4,544 bytes for local variables. Maximum is 8,192 bytes.
avrdude: ser_open(): can't open device "\\.\COM3": The system cannot find the file specified.
avrdude: ser_drain(): read error: The handle is invalid.
im still able to supply power to the printer with the usb port, the LED's still work. did i screw up my board or is this fixable?
