6. Troubleshooting

This section addresses common issues you might encounter with the FoxAlien CNC Offline Controller.

Problem	Possible Cause	Solution
Controller does not power on.	Not properly connected to CNC machine; CNC machine not powered on; faulty cable.	Ensure the cable is securely connected to both the controller and the CNC machine. Verify the CNC machine is powered on. Test with a different cable if available.
SD card not recognized.	SD card not inserted correctly; corrupted SD card; unsupported card size/format.	Re-insert the SD card. Try a different SD card (ensure it's 4GB max and formatted correctly, e.g., FAT32). Reformat the SD card if necessary (backing up data first).
CNC machine does not respond to commands.	Machine is locked; emergency stop engaged; connection issue; GRBL error.	Tap "Unlock" on the controller. Check for any physical emergency stop buttons on the CNC machine. Reset the controller. Verify cable connections.
"Computer mode and offline controller mode cannot be used at the same time" error.	Both computer and offline controller are connected or attempting to control the CNC.	Disconnect the computer from the CNC machine before using the offline controller, or vice-versa.
