Ready Steady Eddy

In the interest of practicality I'm proposing these changes

*emergency stop button pressed - strategy 1
*limit switch activated (NOT home limits) - strategy 1
*Charge Pump error - strategy 1
*'Stop' button pressed - strategy 2 or strategy 4
*spindle over temperature switch activated - strategy 5
*Stepper driver alarm relay activated (e.g. AM882) - strategy 2

The reasons being,
* If the spindle is overtemp then sound an alarm and let the operator take action at the Mach3 screen or otherwise.
* If the stepper driver alarm relay operates then it should be sufficient to issue the 'enable' signal, if not then the emergency stop can be operated.

finding a suitable off delay for the VFD contactor AT THE RIGHT PRICE is proving a challenge right now. There are some cheap ON delays which could be used but would not be fail safe.
