Tooling
Settings → Tooling keeps track of the tools on the active machine: which one is in the spindle, and the lengths measured with a toolsetter. Everything here belongs to the active machine.

In the Spindle
The loaded tool, such as T1, or Not known, and where that came from:
- From the last M6 in a running programme.
- Declared here.
- Carried over — the link dropped or the app restarted since anyone confirmed it.
- No tool change has been seen and nobody has declared one. Type the number to set it.
Type a number in T number and tap Set to declare the loaded tool. When it is your probe's tool number (set in Settings → Connection → Touch Plate), the tab says This is the probe. The spindle is locked out while it is in the collet.
Measurement
Measure on tool change — when the toolsetter measures a tool:
| Choice | What happens at an M6 |
|---|---|
| Every tool change (default) | The new tool is measured, if a toolsetter is fitted |
| Only when asked | Measure in the secured tool-change drawer measures the new tool, then continues; Continue uses its stored length |
| Never | Not measured |
Measure appears at a tool change only with Only when asked and a fitted toolsetter. Never offers no measurement at the change. Measure the loaded tool below remains available under every choice.
Measure the loaded tool — Measure runs the toolsetter cycle on the tool in the spindle and files the length under its number. It needs the loaded tool's number first. While it runs it reads Measuring — step i of n; then Measured. or Measurement failed with the reason. After a failure, put right what the reason names and tap Measure again.
Reference Tool
Every tool length is measured against one reference tool. No reference tool until the first measurement; then the reference's number and trigger height. A tool measured with Measure becomes the reference. Clear forgets it, without asking, and the next measured tool becomes the reference.
If a different tool is loaded, the tab warns that offsets stay correct only while the loaded tool is measured against this reference.
Measured on This Machine
Every tool this machine has loaded or measured: its number, its length or Never measured on this machine, a Name you can give it, and Forget, which removes it at once.
