v12.12 - August 25, 2014

• Back to CNC Bender Software Updates
• See CNC Bender Customer Service Page for an update.

The TUBE SUPPORT POSITION logic is completely redesigned in this version.

The problem in previous versions:

• Problem 1: In the previous version, CNC Bender included a tube support position in the Tool page options. This required operators to be aware of the position. In some cases, operators would accidentally set this position in a way that would cause a crash and break the tube support when the chuck spindle it.
  
  
• Problem 2: The tube support position could be set for slow speeds in the Feed axis, but not move down fast enough for the Feed axis high speeds.

How this feature solves those two problems:

• The tube support positions are now moved to the Low Level page (see the image on the right). These values are no longer saved and recalled on a per part basis. They are part of the default setup and can only be changed by entering the low level page.
  
  
• The tube support positions for the FEED motions that are moving FORWARD are now controlled by SPEED. This allows higher speeds to use a position that is further back to assure clearance.
  
  
• This approach means that operators no longer have to remember to set the positions, and they can be assured that the tube support will get out of the way even if the Feed axis is moving forward at high speeds.
  
  
• The only speed-sensitive tube support positions are for FEED Absolutes moving forward, and FEED Relative Positive commands. All other FEED commands use SPEED 1 Tube Support Position.

CNC Processor can control machine lube at a lower level. This enables machine lube to work even when other motion is occurring. These are the changes for machine lube in this version:

• Depending on the style of switch that indicates the lube is complete, lube complete could be configured to either HIGH or LOW. So now this feature can allow a machine lube switch to be active when it is LOW.
  
  
• In this version , when the feature is active, and the E-Stop is pressed, the lube is immediately stopped.
  
  
• New messages for the machine lube are posted in the Processor log in the CNC Bender user interface.
  
  

Previous versions of CNC Bender would allow characters in part names that made the part name illegal or caused problems to CNC Bender.

• This issue has been resolved in this version with a keyboard that will make the disallowed character buttons to disappear when in the filename mode.
  
  
• When these characters are pressed on the physical keyboard when this mode is active, then the key presses will be ignored.

The characters filter out are:

• < (less than)
• > (greater than)
•  : (colon)
• " (double quote)
• / (forward slash)
• \ (backslash)
• | (vertical bar or pipe)
•  ? (question mark)
• * (asterisk)
• = (equals sign)

The new [Tube Support Override] processlist command is added to this version.

This command can be set to ENABLE or DISABLE in order to override CNC Processor from handling the tube support automatically.

An example use is to add it to the Home processlist to customize the tube support during homing. In this case, CNC Processor would stop trying to control the tube support automatically, and allow the Home process exclusive control.

[Tube Support Override] enable

[Tube Support Override] disable

The new [Tube Support Position] processlist command is added to this version.

This command can be followed by a linear millimeter value that indicates where the tube support should come up or go down.

This new command will work with the new tube support position PER FEED AXIS SPEED support feature in this version.

When the Feed axis speed changes, then the tube support process can also change per the Tube Support page in the Tool menu. CNC Bender manual page and processlists can change the position at any time to accommodate for different Feed speeds.

[Tube Support Position] 1650.0

This would switch the tube support as the carriage passes 1650.0 millimeters from the home position.

• The Cycle Hold and Master Power ON buttons can now be defined so that LOW means activated.
  
  
• The Mandrel HOLD FORWARD bend option for the last bend, and the Mandrel NO ORIGINATE AUTO in Prebend options would sometimes be understood as ON when they were OFF and vice versa. This would cause the Mandrel to not retract in the beginning of the part cycle when it should. This issue has been repaired in this version.
