For the Anycubic Kossel Linear Plus I have to upload data to the 3D printer from a software called Arduino and then close it. Then I open Pronterface and put in the right port and baud rate that is in the Arduino files and then click "connect". Afterwards it says

connecting... 

and that is all it does and doesn't fully connect to the printer. I've tried changing the baud rate and port in Pronterface, Arduino and the bit rate in the Device Manager but nothing works.

Any suggestions on how to fix this?

I know this may be a little late, but I bought the same printer and found that I had problems also. To fix this connection issue I first made sure I had no arduino programs open that were trying the connect to the printer. These would not allow Pronterface to connect to my printer. Then if I still had issues I opened up task manager on my computer just to make sure I had no other programs trying to communicate with the printer. Then if it still can't connect I closed Pronterface and reloaded it a couple of times.
