Downgrade Arduino after firmware update issues

@RemcoVH I can’t change the interface. Thus the only option/solution is to downgrade to the version that worked correctly for me. But that is still not working. First see if you can talk to the Arduino with the Serial Monitor in the Arduino IDE. Set the baud rate to 115200 and the “End of Line” to NEWLINE Once you can talk to the Arduino again we can load in a back rev of grbl.
