Hi,
Can someone pls help me?
This is the first time I am working with arduino and I am trying to make a 3D printer using an arduino Mega r3, ramps 1.4, stepper-motors and Marlin and Pronterface. But now I am starting to build the electric part and trying to make my motors move but when I tested pronterface, it is telling me connecting... but it is stuck there.
I tried to upload only the Marlin part and it gave me the error:
"avrdude: stk500v2_ReceiveMessage(): timeout
avrdude: ser_send(): write error: sorry no info avail
avrdude: stk500_send(): failed to send command to serial port
avrdude: ser_recv(): read error: De ingang is ongeldig. (entry invalid)

avrdude: stk500v2_ReceiveMessage(): timeout
avrdude: stk500v2_getsync(): timeout communicating with programmer
Failed uploading: uploading error: exit status 1"

I have tried checking if the port was connected. I have also tried using a different baudrate and i also used Arduino Ide 1.8.5 and Arduino Ide 2.0.3.0 .
I don't know what to do next and i have checked many other reviews on this topic, but still haven't found a solution.

@mr_nootas
Do you have something connected to the pins 0 & 1 of the Mega board?

I have found the problem.
I used my school laptop and it blocked the arduino usb.
