Spindle will not turn on

The Offline Controller GRBL Status shows STOP. What is the problem and the FIX,

Which model CNC?

Have you tried with a PC attached so that you can see if there are any alarms and what those alarm numbers might be?

Where did the gcode come from that you’re trying to run?

I assume you checked that the e-stop button is not engaged? I had a bad one which was always on regardless of the button position (support told me how to fix that)
