Signal cables and connectors are loose

After the machine has been transported for a long distance or has been running for a long time, it may cause loose cables or unreliable connector contact. In this way, it may cause crashes during system communication. Although this situation is extremely rare, it should be used during machine maintenance and repair. Pay attention to the inspection of the connector.

The number of stitches stored in memory exceeds the allowable value

 When there are too many patterns to be input and the memory capacity is insufficient, the system may freeze. At this time, please check the number of pins in the memory, store the temporarily unused patterns in the floppy disk, clear out the unused patterns, and ensure the running space of the memory.
