So I'm setting up a fixed tool height sensor later today and I've gone over the manual more than a few times just so I'm sure i know what to do (side note: a series of videos for things like this, probe setup, etc would be AMAZING for first time/novice cnc or TNG users), anyways, the manual says this in regards to setting the default sensor position for fixed sensor setup:

"Note that it is very important what kind of tool is used when obtaining Z axis position value, because all future tool measurements will be dependent on this value. That is why we call this tool also a default tool. Default tool should not be too long or too short. It should be some normal length.

Signs that your default tool was not suitable are usually Z axis plunging into machine table or Z axis activating limit switch after tool offset measurement."

Now i have tools that range from 0.5" stick out to 3"+ stick out. What do i do in this case? I don't want to pick a tool that's too long to where my shorter tooling won't even touch the sensor during a tool change, and i definitely don't wany to pick a tool that's yoo short that cause the tooling to gouge the table or break.

All of this still doesn't even take into account face mills, which would have all different axes values, not just z height.

Now I'm pretty new to all this and might be overreacting. Maybe i can set the default values with a short tool and the sensor will automatically know what's up when there's a longer tool, but i don't want to mess anything up finding out.
