I am trying to install the latest dev version 4.2, I have configured using the online configurator and have downloaded the file. Using the latest veriosn of the Aurduino IDE after uploading Pronterface will not connect. When I click the connect button in Pronterface it appears to reset my controller becasue the LCD screen clears then displays the Kimbra marlin 4.2 screen then the printer info screen.
I have verified the COM port and baud rate are correct. I flashed the old Kimbra Marlin 4.1.2 and it works as expected (other than the random issue of G28 rapidly moving Z up faster than my steppers can handle stalling them)
