There were no macros in my macro folder. There are in the default profile, but I created a custom one and there are none.
Now, this is strange. I was looking at the diagnostic page and clicking the spindle on button to see that the LEDs changed. They did change as expected. I clicked the ref X button and the spindle motor started, regardless of the spindle button state. Once started the only way to turn it off was to exit mach4.
Anyone seen this happen?
