How to restore the Z-axis limit alarm of CNC engraving machine?

Under normal circumstances, when the CNC engraving machine turns on the control system, it will prompt a limit start emergency signal. This is not a mechanical problem, but because the emergency stop button on the control cabinet of the engraving machine is not turned on to trigger the limit signal, and the control software will prompt a limit signal. Activate emergency signal.

Solution: As long as the emergency stop button is turned on, the fault can be solved immediately.

Another situation: the parameters in the I/Q status window of the CNC laser engraving machine are disordered. At this time, the parameters need to be modified. The solution: click on the x-axis, ctrl+shift+alt and then right-click. When the window pops up, click "Reverse the point Towards". Click on the y-axis, press ctrl+shift+alt and then right-click. When the window pops up, click "Reverse the polar direction of the point". Click on the z-axis, then right-click with ctrl+shift+alt. When the window pops up, click "Reverse the polar direction of the point", and then close the control window. After the above operations are completed, restart the engraving machine control system and the engraving machine control system can work normally.

There are also a small number of cases where the control software program of the CNC engraving machine is damaged. In this case, the control system needs to be reinstalled.
