ENHANCED: Improved and Safer Shutdown

Explanation

• CNC Bender software saves its current state and setup in a configuration files and registry entries software during shutdown.
• If the standard shutdown procedure is bypassed due to a loss of power or a system crash, then CNC Bender, in previous versions, may attempt to write a file - only to be interrupted in the shutdown task.
• The result is a possible corruption of this file.
  
  

Solution To Issue

This version solves the problem by placing an intentional delay between the time the operator requests a shutdown and the time the configuration data is written to disk and registry.

The delay message looks like this:



So...



Regular Shutdown

1. The operator requests shutdown of software.
2. CNC Bender hides the interface.
3. CNC Bender displays a shutdown message on the screen showing a progress bar.
4. After the progress bar is filled, CNC Bender saves its configuration data.





Immediate Power Loss Shutdown

1. A loss of power to the operator station occurs.
2. CNC Bender is not given time to perform a normal shutdown.
3. CNC Bender will shutdown before it attempts to save a partial file and potentially corrupts the configuration data.
