Cause: One or more broken wires.
Broken wires cause intermittent errors that become more frequent as they are ignored. In our experience while troubleshooting CNC routers, when one wire breaks, more will follow. These intermittent and seemingly random errors are easily fixed and can save your factory costly down time.
