I am plugging the pi in to the type B USB port and i keep getting the following error:
Error: Failed to autodetect serial port, please set it manually.
The pi is fine, it worked onthe previous melzi board, but now it wont connect to the MKS board. Is there some setting I am missing here? Any help appreciated.
check com port and make sure you don't have your 3dsyms software trying to connect before you got the cable plugged in.
It will think port is being used.
Most likely the baud rate is wrong.
You don't mention what software is giving the error, so it's hard to give specifics, but it's worth trying a couple of different rates to see if they work. Google isn't easily telling me the "right" one, but 250000 and 115200 are the most common. Trying a wrong one isn't likely to hurt anything though.
