Finding Home (Rotary Encoder)
You must find home before you run a program. To find home immediately after startup,
locate the Z-axis at the top of the fixed mark then press the
FIND HOME softkey.
Otherwise, press the DATUM softkey, then the FIND HOME softkey. The table will auto-
matically move a short distance along the Z-, Y- and then X-axes to find home. Z-axis
finds home first. You will have to locate the Z-axis at the top of the location mark before
finding home.
When finding home, MILLPWR will use ACU-RITE’s advanced Position-Trac ™ technolo-
gy. Position-Trac works by using a very precise distance-encrypted reference mark line
pattern that's been placed onto each ACU-RITE precision glass scale included with your
MILLPWR system. Proprietary software decodes the line pattern which then allows you to
accurately find home and reestablish workpiece zero from any position.
With Position-Trac, there is no need to leave the system powered up when it is not being
used. You’ll be able to easily, quickly and accurately reestablish workpiece zero after
power loss.
After home has been found, the tool’s position (relative to your most recent datum) will
be displayed.
If you don't find home before moving the table, you will
risk exceeding the table's travel limits and damaging the
milling machine,
MILLPWR or both.
