Find Home
You should find home before a program is run, or immediately after
startup.
 During start up, the Find Home soft key is provided on the start up
screen soft key area.
 If the find home step is not performed at initial start up, it can be
initiated at any time during operation. Press the Datum soft key, then
press the Home soft key, and then press the Find Home soft key.
 A 3 axes system will move the table and quill. They will
automatically move a few inches along the Z, Y, and then X to find
home. If a W axis exists (i.e. coupling knee to quill) then the control
will prompt you to move the W manually to home it.
 A 2 axes system will move the table. The table will automatically
move a few inches along the Y, and then X to find home. Then the
control will prompt you to move the Z quill manually to home it. If a
W axis exists (i.e. coupling knee to quill) then the control will prompt
you to move the W manually also to home it.
When finding home, the MILLPWR
G2
will use (on machines equipped
with ACU-RITE glass scales), the Position-Trac™ distance-encrypted
reference mark line pattern. This line pattern allows MILLPWR
G2
to
accurately find home and re-establish workpiece zero from any
position.
Position-Trac will accurately re-establish workpiece zero after power
loss, or shut down. After home has been found, the tool’s position
(relative to the most recent datum set) will be displayed.
Before finding home with a 2 axes system, the quill must
be fully raised first.
Finding home applies to the X, Y, Z, and W axes.
Not finding home before moving the table will risk
exceeding the table's travel limits, and possible damage to
the machine, and the MILLPWR
G2
system.
Programs will not be allowed to run if the homing process
does not complete successfully.
The Find Home soft key is not available if there is an error,
and the front panel LED indicator is flashing.
The error must be corrected, and then cleared from the
error log. Then homing is allowed.
Refer to Chapter 9 "Error Log" on page 183 for information
on opening the error log and deleting errors.
