ProbeApp for Mill & Routers that integrates with Centroid CNC12
Find the center and top of a Rectangular Stock to set WCS 0 for X, Y and Z-Axis with one probing cycle. This probing cycle is available for all versions of CNC12.
Note that this probing cycle can also be used if you want to set WCS 0 at a corner of your model and you want to distribute the excess of the X and Y-Dimension of the stock evenly around your model for better machining. For that use case, you would configure the X and Y-Offset to half of your models X and Y-Dimensions. You can specify a positive or negative offset depending on what corner of the model you would like to set your WCS 0.
Any of the four sides of the rectangular stock can be selected as the start point of the probing cycle. The probe needs to be placed at the approximate center of the selected start side. The Z-Height has to be set at the level the measurements needs to be taken on the surface.
The probe will make the following moves and measurements:
At the end of the probing cycle, the probe will be at the center of the Rectangular Stock at the Probing Recovery Distance (System Parameter #13) above the Z-Surface and the X and Y-Width 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.
Be aware that the DRO for the Z-Axis will not show 0 after the WCS reset as the probe is above the Z-Surface by the Probing Recovery Distance (System Parameter #13) when the WCS is being reset.
The Approx. X/Y Width is the distance the probe needs to travel accross the stock along the X/Y-Axis to get to the opposite side. Be generous with this amount and rather error on the plus side rather than being too short.
If this amount is too short, the probe will be tripped while trying to move down on Z to get to the probing height. When this happens, the retry cycle will be activated that will advance the probe in increments until it’s clear to drop down on Z. Should the retry cycle hit any limits (e.g Probing Search Distance or travel limit) the probing cycle will be aborted with an error message.
The Z-Clearance Amount specifies the distance the probe needs to move up on Z from the start point to traverse to the opposite side. Be generous with this amount and rather error on the plus side rather than being too low.
If this amount is too low, the probe will be tripped while trying to traverse. When this happens, the retry cycle will be activated that will advance the probe in increments until it has enough clearing height to traverse. Should the retry cycle hit any limits (e.g Probing Search Distance or travel limit) the probing cycle will be aborted with an error message.
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 Rectangular Stock for the currently Active WCS.
All 3 axis allow to set WCS 0 at an Offset 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:
Any of the available WCS # can be selected to be reset by 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
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.
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.
