X-carve Grbl Default Settings - 500mm

I’ve been helping folks get their X-carve machines up and running. I’ve learned a lot. One of the things that I have noticed is that the grbl parameters seem to be inconsistent, especially when the Arduino has to be re-flashed. Long story short I wanted to find out exactly what the defaults should be. I took a new Arduino and used the EEPROM clear example program to clear the contents of the EEPROM (1024 locations), compiled the source code for Grbl 0.9j, downloaded to the Arduino, then ask fo…
