14.1. How Tool Setter Works
Overview
A tool setter or a simple touch plate can be wired to MASSO and is used as a reference surface with the
Auto Tool Zero feature.
When MASSO is homed the tool currently installed in the spindle is touched off of the tool setter.
From this touch off MASSO can measure the length of the tool in the spindle and stores this length to use as
a comparison in future tool changes. This value will remain valid until the machine is homed again or it is
turned off. The tool can now be zeroed to the surface of the stock as required.
WARNING: If you do change or alter the tool height without being instructed to do so by MASSO
you must home your machine again. Failing to do so will cause the 2nd tool change and all
following tool change heights to be wrong causing damage to your work and machine.
When MASSO is asked to change tool using the M06 GCode command it will measure the new tool length
and compare it against the original measured tool, then adjust the tool height offset accordingly.
It is therefore critical that once the tool is measured that it is not changed or it's length altered as this will give
incorrect tool heights on all future tool changes.
Because the Tool setter is a reference surface the height of the tool setter does not matter so long as it does
not change it's height.
The tool setter should not be confused with a probing touch plate which is used to measure tool height above
the surface of the material which requires the height of the probing plate to be known.
Prerequisites
To use a tool setter you must have homing setup on you machine so that the spindle can find the tool setter.
