Secondary Processlist

A secondary processlist is a list of commands to move devices simultaneously while the bender is bending a the tube with the main processlist. Secondary processlists multitask with the main processlist and CNC Processor allows for any number of secondary processlists to run during the main cycle.

This is secondary processlist that controls an autoloader. This process runs independently of the main bending process as long as CYCLE START is active:

// Open the grippers and return the loader

// Decrease the priority of this list now

  [DISPLAY] LOADER - Decrease Priority of Secondary List 1 (0.250 secs)
