Cncv12procontrol withteachmode.jpg



Check.jpg NEW - CYCLE HOLD in Custom Commands and in TEACH Mode

Now CYCLE HOLD anywhere inside a CUSTOM COMMAND either manually entered or taught during TEACH MODE.

Cycle Hold pauses the process perpetually until Cycle Start is pressed.

See also the Cycle Hold button.

Check.jpg ENHANCED - ENABLE Button for STEP and AUTO Modes

The "REQUIRE ENABLE BUTTON" feature, when active, now also monitors for a switch to AUTO or STEP modes from MANUAL mode

When this feature is enabled, then the ENABLE button must be pressed or a large message will display indicating that the operator must press the ENABLE button

Check.jpg ENHANCED - Vertical Head Shift Tolerance Added

The vertical head shift tolerance allows us to skip motion when an axis is close enough to the final position.

The tolerance value is now present in the Low Level General Options list and is used by the processlist compiler to give the Processor more efficient processlists.

Check.jpg ENHANCED - Added CNC Processor Automatic High Pressure Handling

CNC Processor now uses the CIO Name Cross Reference in the Low Level menu to automatically set the high pressure under these two special circumstances:

  • Just before CNC Processor performs a direct axis jog, CNC Processor sets the CIO point for high pressure.

  • When CNC Processor switches from Cycle Hold to Cycle Start, CNC Processor sets the CIO point for high pressure.

Check.jpg ENHANCED - More Features for Soft EOT for Each Axis - JOG Speeds Ramp Down

During JOGGING - CNC Processor can check for EOT (end of travel) of an axis before it arrives at the true FAULT EOT. This gives the axis a chance to stop jogging before it arrives at a FAULT position or emergency switch.

The changes are setup in the main.axislist configuration for each axis.


The following section is extracted from an AXIS configuration file soft EOT section:

  • Enable EOT= 1 or 0
  • Low EOT= (floating point value)
  • High EOT= (floating point value)
  • Jog Speed= (positive floating point value of regular jog speed)
  • Jog Speed Approach EOT= (positive floating point value of ramp-down jog speed)
  • Approach EOT Range= (positive floating point value of the range in which the slower jog speed is enabled)


Example of what to add in each AXIS in the main.axislist file. The value shown here are typical of the BEND axis: 

Enable EOT=1
Low EOT=0.75
High EOT=191
Jog Speed=10
Jog Speed Approach EOT=0.5
Approach EOT Range=5
In the example given here, when the bend arm is more than 5 degrees from the soft EOT, it travels at 10 degrees per second. However, when it reaches within 5 degrees of either EOT, then the speed drops to 0.5 degrees per second.
