At this point, we can set the material base in X-axis by clicking „Zero X”
button on the Mach screen. Coordinate X on the screen will be reset.
Switch the feed rate mode on continuous one, „Slow Jog Rate” speed – e.g.
2% because we are very close to the material and the same way we set the
Y base on the lower edge of the cube. This way of homing seems to be a
little troublesome but with a little practice this can be done very quickly, besides it is quite precise.
When the position is set on the lower edge of the material then click „Zero Y”, to reset the Y coordi-
nate at this point.
If we do not use the automatic tool length measurement, setting a
Z base at this point makes no sense. You should set it only if we
place the right tool. However,
I assume that such a sensor is
installed in the machine.
For Z-axis, we set the base
much like XY, raising the axis a
little higher above the materi-
al level, next lowering it in
stepper mode until the lower
roller surface touches the
material. Now click the „Zero Z” to reset the Z coordinate at this
point.
The material base is already set so you can place the correct milling cutter – to plan the surface
measure it and load the trajectory file.
After we placed the tool, we measure it clicking „Auto Tool Zero” button.
Automatic tool length measurement is not a standard Mach3 function. Description of this function
activation and configuration you can find in chapter 14.1 – „Automatic tool length measurement”.
