Home and Auto Tool Zero

1

I have an Elite Foreman with the OneFinity tool setter.

With the tool setter configured, the machine will automatically zero the tool using the tool setter when a home operation is performed (or after a tool change).

This “auto tool zero” operation tells the machine at what Z offset the tool presses the button on the tool setter. However, how is that information useful without it knowing the Z height of the tool setter button?

The height of the tool setter could vary significantly depending on whether it’s mounted on the waste board or on the QCW tube. When I installed it, I was expecting a step where the height was measured and recorded by the controller.

I must be missing something because I’m failing to see how the machine gains any useful information about the tool height without knowing the tool setter Z height to offset against.

Thanks for any help to clarify this issue.

It measures from the home position at the top.

Tool setters only determine tool height offsets relative/between measured tools, so the location of the tool setter makes no difference - as long as it remains in that location for all tool offset measures.

The tool table - F4 - records these relative offsets/Z heights.

The value comes after you zero the firsts tool for your first machining operation, and subsequent tooling will then - using the measured offset - be at the same/correct Z zero to continue machining.
