I'm just wondering is there anything maybe slightly different when measuring a touch probe to add it to the tool library as maybe T99 and using it as a reference tool for setting up my WCS so that any other subsequent tool changes follow along with the correct offsets. Do I just treat the touch probe like any other tool since pre-travel is almost 0 when touching off in the Z axis.
You posted your question in an expired ProbeApp thread. If you have questions about the ProbeApp, please post in the new thread here.
You mentioned that you have a spindle with a non-fixed, collet style tool holder. That means you cannot use the method that Keith describes in this video as this video shows the process for fixed tool holding. With collet style tool holding, the tool and/or the touch probe will have a different length every time you change the tool so it's really pointless in this case to store the tool length in the tool offset library as the length will change the next time you use that tool or touch probe. You need to measure each tool again after each tool change.
As you have posted in the ProbeApp thread, I assume you are using the ProbeApp and the ProbeApp does have the "Tool Setter" cycle that's specifically designed for machines with non-fixed tool holding to integrate the tool change and tool length measuring process into the job flow without the need to stop/restart a running job.
There are two supported methods in the Tool Setter cycle of the ProbeApp, one is the single TT method with a movable Tool Touch Off Plate (TT) and a dual TT method with a fixed and a movable TT where the fixed TT could also be the same as the movable TT just always placed at the same location on the machine table for a fix TT touch off. The dual TT method will give you more automation as all subsequent tools will automatically be measured with the fixed TT. It also allows to use the touch probe (TP) to initially set WCS X0 Y0 and set the reference distance between the top of the workpiece and the top of the fixed TT. This reference distance is used for subsequent tool changes to always adjust WCS Z0 to the bottom of the tool touching the top of the workpiece.
There is a separate thread on the Centroid forum describing this process: Guide on how to measure Tool Heights and set WCS Z0 on a Router or Mill with none-fixed Tool Holders most efficiently
It's also described in the Tool Setter chapter of the ProbeApp User Guide.
Let me know if you have any more questions or something is still unclear.
