t's a long story. I was trying to solve my printing problem described in this post. The printer was connected to the computer then and the power is on. I was adjusting the current of my y-axis motor, and I accidentally touched something with the screwdriver. Then the driver of the motor sparkled in an instant. I didn't realized that it's a problem until I checked my computer after all those thing happened, I found that it disconnected by itself. The fan on my PSU was on and the LEDs on Mega and Ramps were on and everything seemed on.
However I just couldn't connect it again. I believe that the usb cable is fine. The usb cable was providing power to mega, because even when the main PSU is unplugged the led will still be on if the usb cable is connected.
When I tried to connect the printer while the usb cable is connected Printrun said:
"[ERROR] Could not connect to /dev/tty.usbmodem1411 at baudrate 115200:
Serial error: could not open port /dev/tty.usbmodem1411: [Errno 2] No such file or directory: '/dev/tty.usbmodem1411' "
(115200 is my usual baudrate.)
So, is any of my parts broken? Or will the problem disappear in some time?
