Regular Bore Probing Cycle

Description

Find the center of a Bore Hole. This probing cycle is available for all versions of CNC12.

Implementation Details

The probe needs to be placed in the approximate center inside the bore hole. The Z-Height has to be set at the level the measurements needs to be taken inside the bore hole.

The probe will make the following moves and measurements:

• Move to the X- side for the first measurement
• Move to the X+ side for the second measurement
• Move to the calculated X-center based on the two X-measurements
• Move to the Y- side for the third measurement
• Move to the Y+ side for the fourth measurement
• Move to the calculated Y-center based on the two Y-measurements

At the end of the probing cycle, the probe will be at the center of the bore hole and the diameter of the bore will be displayed:

Note that this message can be surpressed if “Set WCS after probing” is checked and the configuration settings have been made to skip the measurement display. See Configuration Options for details.

If “Set WCS after probing” was checked, the WCS reset message will be displayed:

Note that this message can also be surpressed if a direct WCS reset is desired withou a prior WCS Reset Info message display. See Configuration Options for details.

Probing Parameters

The only parameter for this probing cycle is the “Set WCS after probing” checkbox

If the WCS box is checked, at least one of the Axis needs to be checked too. By default, WCS 0 for the axis will be set at the center of the bore hole for the currently Active WCS.

Both axis allow to set WCS 0 at an Offset from the center if needed. For an offset in the negative axis direction, a negative value needs to be entered.

Note that the available WCS numbers depend on the version of CNC12:

• CNC12 Free: Only WCS #1 (G54) is available
• CNC12 Pro: WCS #1 - #6 (G54 - G59) are available
• CNC12 Digi: WCS #1 - #18 (E1 - E18 where E1 - E6 is the same as G54 - G59)

Any of the available WCS # can be selected to be reset by the probing cycle.

Start the Probing Cycle

After making all the selections necessary on the screen, pressing the START button will start the parameter validation. A message will be displayed if any of the parameters are missing or invalid

If no validation issues have been found, the ProbeApp will write all the necessary probing commands to

c:\cncm\ncfiles\probing_cycle.cnc

The ProbeApp will close giving control back to CNC12

At this point the Probing Cycle can be started by pressing Cycle Start or aborted with Cycle Cancle.

Closing ProbeApp without a Probing Cycle selections

The Probing Cycle screen can be closed by either pressing the X on the top right corner of the window or pressing the Green Back Arrow on the top left. This will open the ProbeApp main window where the Exit button can be pressed.

Control will go back to CNC12 where this message will be displayed:

Pressing Cycle Cancle will terminate the cycle immediately. Pressing Cycle Start will bring up this message:

Pressing Cycle Start at this point will also terminate the cycle.

3-Point Bore Probing Cycle

This is a special version off the Bore Probe Cycle that is activated by checking the box 3-Point Probing. This cycle is useful if not all 4 sides of the bore can be used (e.g. one side has been milled out).

Select the 3 points that should be measured. All the other functions work the same way as the regular Bore Cycle.
