Well, I recreated it and confirmed cycling VFD power without rebooting LinuxCNC makes the spindle run again.
I looked into the HAL after the "Spindle CW" button breaks everything: enable TRUE is_alarm FALSE is_at_speed FALSE is_ready TRUE is_running TRUE reverse FALSE run TRUE watchdog_out TRUE compared with actually having it running with M3: is_at_speed becomes TRUE (duh) watchdog_out is FALSE Well, that's odd. IIRC the watchdog is not getting data back from the VFD in a timely fashion. It is somehow locked up so that does seem consistent with the situation. But no idea how it's getting locked up. The x200 VFD code sends a speed, dir, and run command and reads back the coils.
