CNC Setup
Auto home setup
When encoders are used that include reference marks, or
when limit switches are used in place of encoder refer-
ence marks, the location of machine zero can automati-
cally be found by the system when the QC-320 program
is launched.
The Auto home screen provides fields for configuring
CNC auto homing direction and search velocity for each
axis.
Configuring auto home
The process of configuring auto homing parameters is identical for all axes. To configure an axis for auto
homing:
1 Check or clear the Start moving in negative direction box to
specify the initial CNC search direction for the desired axes.
2 Enter the desired search velocity as a percentage
of the maximum velocity directly into the desired
Search velocity data field.
Only search for reference marks after the end of travel
Encoders with multiple reference marks (other than C-scales) must be driven to the end of travel prior to
searching for the unique mark that will repeatedly be used to define machine zero.
1 To specify encoders with
multiple reference marks, check
the Only search for reference
marks... box.
Enabling/disabling auto homing
1 Check or clear the Enable box to enable or disable auto homing.
