Dear All, I had XPRO V3 working fine, until this afternoon. I was configuring homing settings and after making necessary changes to grbl config.h file and compiled it in Arduino, I was flushing the .hex file to my XPRO board, when suddenly all the light on the board turned off and I can only see the 5V green LED, and flickering green LED on the USB port on the board. The flickering is as if it is being programmed but after waiting for long minutes and minutes, this doesn't stop at all, so this is actually not being programmed. Turned all powers off and reconnect all cables and tried to power on the board, but there is only the 5V green LED, this time this is from 24V reaching the board. Other than that no LED of the motors is on, lifeless. Universal GCode sender, connects to the port but grbl information is not replied. I am posting this to others too, as I am a bit panicking. Help, please.
Refer to 5. Troubleshooting · Spark-Concepts/xPRO Wiki · GitHub 1) ensure you flashed official Grbl 1.1f from GitHub - gnea/grbl: An open source, embedded, high performance g-code-parser and CNC milling controller written in optimized C that will run on a straight Arduino (GNEA is the official version) - flash a stock version first, your changes may be the issue 2) compare settings to XPRO wiki (especially Enable Invert relative to your XPRO version as outlined in wiki)
