I can't seem to uplaod to my board. It worked once with everything disconnected but won't work any longer. Really dont' want to label everything again and pull my printer apart again to remove all the connections to test.
I'm running windows 10 pro 64 bit
I have a MKS gen L v1.0 board
I have tried disconnecting the screen and BL touch and tried uploading when the board is powered by usb and by printer power supply. The message I get is "the selected serial port does not exist or your board is not connected" The board is connected and shows up as COM 5. When I disconnect the board, COM 5 disappears, so I know that's the right com port.
Here is my error message:
