I'm experiencing an issue with my CNC controller regarding the Z-axis soft limit. Specifically, I received a warning message indicating a problem at line 754. This has halted my operations and I need guidance on how to resolve this issue effectively. Could you provide me with troubleshooting steps or any recommended solutions to clear this warning and restore the functionality of the Z-axis? Any detailed instructions or insights would be greatly appreciated, as I'm eager to get back to work without further delays.
