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 Issues During Feed/Rotate Motion When Bend Arm Returning

  • There were circumstances were the Feed positioning axis accuracy could decrease unacceptably by Processor making multiple calls to the BEND axis when the BEND axis was returning to ZERO, and the Feed/Rotate axes began to move at the same time.

  • After several tests, we have confirmed that this version of CNC Bender completely RESOLVES the issue.

  • 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:
  1. The "Don't Move if Within Position Tolerance Of" value in the AXIS configuration file - where axis moves are skipped when they are already in position.

  2. ...Combined with 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).



Check.jpg CHANGE - Removed Option from AXIS File

  • The "Dont Move If Position Within Tolerance Value" value is no longer uses

  • This resolves issues discussed in the previous section.

  • This line can be safely removed from all future main.axislist files

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

  • 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.

Explanation of 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.
