SITEST
X Start SITEST.
X Select
Single Functions
and perform (for all heads) a
head reference run
.
X Select
Gantry-Gantry axis functions
and perform a
reference run
for the X-axis.
X If the single reference run is successful (no errors), perform a
complete reference run
.
X Calibrate the
Machine zero point:
(for both gantries if using a D2).
X Save the machine data.
4-4: Fixing the X scale
X Place the scale in the previously marked
starting position and press it down firmly in this
position.
ATTENTION: Make sure the scale is
not bent or rubbed against any
parts.
X Move the adhesive device with the head
mount. While doing so, press the scale firmly
against the adhesive surface with your finger
(see fig.).
ATTENTION: Make sure that no
blisters or uneven areas are formed.
If this does occur, the scale must be
removed and replaced with a new
scale.
X In order to fix the last part of the scale, move
the head mount back and press the rest of the
scale down firmly with your hand.
X Make sure that the whole scale is fixed firmly
onto the gantry.
X If necessary, clean the scale and the
incremental encoder lens again.
X Fit the incremental encoder with the two
fastening screws so that there is a gap of 0.4
mm between the incremental encoder and the
scale. Use a suitable thickness gauge
(plastic). (See also: "Replacing the X-Axis
Incremental Encoder " in the service manual).
X Move the gantry out of the table area.
X Switch the machine on.
X Insert the changeover table into the machine.
