Hello everyone,

I'm having an issue with a CNC milling machine that uses an HCN 210A control unit. When I start the machine, it gets stuck in "handle" mode, and I'm unable to switch modes. Occasionally, it will allow programs to run in automatic mode, but during operation, it reverts back to "handle" mode. Some days, the machine becomes completely unresponsive.

Has anyone encountered a similar issue, or does anyone know if updating the firmware might resolve the problem? Any advice or suggestions would be greatly appreciated!

Thanks in advance for your help.
