I'm using Marlin 2.0.9.3 and windows. I have been successful in uploading firmware but when it comes to connecting the board to my computer (I'm using pronterface) it won't connect. Before you give me the same responses that I've been getting from everyone on the internet.
Yes I have set serial port 2 to be -1 Yes I have tried to update drivers (couldn't really find them though) Nothing shows up on the device manager
I'm probably doing one small thing wrong, but any help is appreciated
