Problem 1: Machine displays an error upon startup.
Solution: This is almost certainly caused by an incorrect data cable connection; try reconnecting the SATA cable, or replace it entirely.

Problem 2: “Motion init failed” error displayed when the machine is powered on.
Solution: 1. Check for slow or obstructed movement. 2. Check for issues with the limit switches. 3. Restart the machine.

Problem 3: The take-up and feed motors are not operating.
Solution: The controller is receiving power input but does not light up and produces no voltage output; this indicates a faulty controller, which should be replaced immediately.
