I have just updated my grbl firmware to 1.1f and now the real time x y z positions just show NaN.000? . Any ideas , or should i just go back to an earlier version. i dont think there is any feedback from the board.
The grbl workspace is not compatible with grbl 1.x. A compatible work in progress workspace is available at /jpadie
Thanks, i have reverted back to version 0.9. Working fine again now.
Thanks for posting this Jon, I had the same issue.
If you have issue in unit conversion(imperial and metric) try my work space: /hyun
