Type of Upgrade: Critical: ACCURACY

The changes in this version are designed to make CNC Bender more accurate and run faster.

Check.jpg REPAIR - Feed Accuracy Fix During Feed/Rotate Motion When Bend Arm Returning

  • There were circumstances were the Feed positioning was interfered with by Processor making multiple calls to the BEND axis when the BEND axis was returning to ZERO.

  • We discovered this problem running on a new high-speed Pro-face operator station running LiteControl.

  • We are convinced that this issue could occur in any bender with newer software being run in a fast Pro-face control.

  • The issue is directly linked to the "Don't Move if Within Position Tolerance Of" value in the AXIS configuration file, and situations where multiple axes are called simultaneously in the same COMDEF (like when the bend arm is returning and the Feed/Rotate axis starts up).

  • The "ignore" Axis property is now ignored and can be removed from the axis file.

Check.jpg REPAIR - For [BEGIN RUN AGAIN] Feature

  • As of version CNC Bender v11-20091104, CNC Processlist Builder inserts a new [BEGIN RUN AGAIN] label placed in the middle of each part's process list to trim off processing time. This allows CNC Processor to skip the initialization section of each new part after it has been run once.

  • We discovered that the switch to the [BEGIN RUN AGAIN] label did not occur until after the second time through the processlist. This increased time slightly, and sometimes caused the bend arm to pause on the way to the home position when the "Last Row Absolute Feed Clear - Immediate Move" was ENABLED.

  • This problem has been resolved. Parts now run faster on the second time through the process, and the bend arm motion will not be stopped and restarted while returning.

Check.jpg NEW - Second Constant Run List Designed for HIGH SPEED OPERATIONS

  • USe the new high-speed constant run list for processes that should run all the time and get high attention.

  • Control the interval of how often the list runs in the Processor tab in the Low Level menu.

  • The list file is separate from the ConstantRun processlist. The name is "ConstantRunHS.processlist"

  • Put tube-support control in this list to make it more responsive to fast moving Feed axes.
