Enables/disables 'Enable' signal for all of controller’s axes.
Soft Limits Enable
Enables/disables software limits of machine.
Machine will be able to move outside of software limits set with Motor Limits. Motor limit values are set in File/Settings/Motors/Limits.
Hard Limits Enable
Enables/disables hardware limits (limit switches) and probe inputs of machine.
Machine axes will move despite corresponding axis limit switch or probe input being active.
Limits switch parameters are set in 'File/Settings/Motors/Limit Switches'.
Probe parameters are set in 'File/Settings/Program Options/Probe & Measure'.
Probe Trigger
Simulates active probe input.
This feature comes very handy in case if you use PlanetCNC TNG in simulation mode where user need to simulate hardware probe input.
You can use shortcut for this feature for easier use.
