The Auto Tool Zero Settings screen controls how MASSO measures tool length using a tool setter.

Enable Auto Tool Zero

Enables the Auto Tool Zero function for measuring tool length:

• During the homing routine

• Between tool changes

Without a tool setter installed, each tool change will require a separate G-code file, as the tool setter is an integral part of tool changing in MASSO for both manual and automatic tool changers.

For more information, see: Auto Tool Zero

Only Auto Tool Zero When Manually Requested

This option is intended for machines with:

• Automatic tool changers, or

• Tools installed in fixed-length holders

   

When enabled:

• Tools are not measured during homing or tool changes

• MASSO uses the tool length entered in the F4 Tool Table

• Tool height is set using the stored tool length during program execution

Tools must be measured using Auto Tool Zero from the F4 Tool Edit page:

• Only required when a tool is first installed or replaced

Tool Setter X & Y Position

Defines the machine coordinates of the tool setter on the table.

• If an axis is not enabled, the spindle will not move to that coordinate

• The tool setter must be located within the machine soft limits

For more information, see: Auto Tool Zero

Z Safe Distance to Tool Setter

Defines the machine Z position the spindle will rapid down to before probing begins.

• Useful for machines with a long Z axis
