Soft limit warning

If the control unit gives a soft limit warning when you press the start button, in most cases there is nothing wrong. 

This means that the controller knows it is attempting to exceed its table limit with the written g-code. In most cases, this applies to the Z-axis. The g-code specifies that the Z-axis must move down by, for example, -100mm. The maximum soft limit is set to -85mm. The controller therefore wants to go beyond its limit and asks if that is acceptable. However, the controller does not know that in this case, it will be stopped prematurely by the plate thickness detection (Probe).

When the workpiece is larger than the X and Y axis machine coordinates, it is a different story. In that case, if you accept the warning, the control system might attempt to move outside its range, causing the motors to hit the limit stops.
