I had GRBL Offline Controller board. When I received the controller, it is had 3 files to test the machine. The machine worked well (3018). But, when I load files to the controller from Easel, the controller did not start the machine. Why??
I had the exact same problem.
So far my solution was to make sure easel has the machine set for spindle control to automatic, also I have to run the.nc file through the candle program and save from that onto my offline controller. I’m still new but so far that has worked.
