Tutorial: How to Change the Tube Support Point

Follow these steps to change the tube support point:

• STEP 1
  Enter the low level menu of CNC Bender.

• STEP 2
  Select the Init Axes tab.

• STEP 3
  Find the line in the Init Axes configuration that looks like this:

// Set the Feed Programmable Limit Switchs
FeedAxisPLS5 = LSL0:1500.1, LSU0:3000
FeedAxisPLS4 = LSL0:1, LSU0:1499

• STEP 4
  The values are from the back of the Feed axis toward the front in millimeters. The PLS4 command parameters are ranges for when the limit switches are active.
  
  For example, the LSL0:1 to LSU0:1499 refer the range when the tube support should be UP because the carriage is far enough from the bend die. In this case, the 1499 value could be change to a higher or lower value to adjust that output. For example, if you want the tube support to drop when the carriage is at 1600 millimeters from home, then enter 1599 after LSUO: on the PLS4 line.
  
  The PLS5 line's LSL0 value should also be adjusted. In the example above, if you were to use 1599 in PLS4, then enter 1600.1 for LSL0 of the PLS5 line. The LSU0 value for the PLS5 should be beyond the front of the bender (3000 is usually enough).

• STEP 5
  Save the change with the Save / Update button in that menu.

• STEP 6
  Close and restart CNC Bender.

• STEP 7
  Slowly jog the feed axis forward to test your change. Does the tube support drop when expected? If it does, then the change is complete.
