Single Axis XYZ Probing Cycle

Description

Find the position of a X, Y or Z-Surface. This probing cycle is not available for CNC12 Free.

Implementation Details

The probe needs to be placed next to the X or Y-Surface or above the Z-Surface to be probed. For X and Y-Surface measurements, the Z-Height has to be set at the level the measurements needs to be taken at the surface. For Z-Surface measurements, the probe can be placed at any distance above the location where the Z measurment needs to be taken.

For X and Y-Surface measurements, the probe will be away from the probed surface by

(Probing Recovery Distance [System Parameter #13]) + (Probe DIameter /2)

For Z-Surface measurements, the probe will be above the probed surface by

(Probing Recovery Distance [System Parameter #13])

The position of the probed surface location 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.

Also be aware that the DRO of the axis that’s been reset will not show 0 as it does with most probing cycles as the probe will be at a retracted position by the time the WCS is being reset.

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

With the Single Axis probing cycle, only the axis that has been probed can be reset. By default, WCS 0 for the axis will be set at the measured surface position of the currently Active WCS.

It is possible to set WCS 0 at an Offset from the measured surface. 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:

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.
