I’ve been trying for 2 nights now to get a simple gcode file to execute. I can jog the spindle around, zero it out, and home it just fine. But nothing I do seems to get it to run the gcode. I noticed next to the play button there is a little clock icon that says that it is being asked to pause sending commands to not overrun the buffer. However, on the grbl panel it says the state is idle and it responds right away while jogging the spindle, and that panel also has the clock icon.
I moved the spindle into position, zeroed my axes, loaded my gcode and hit play. I expect it to begin cutting but nothing happens.
Where can I look for debugging information? It seems like somewhere it is getting the idea that the cnc is busy, but it is idle.
Any pointers would be greatly appreciated.
