DANGER
Strong permanent magnet fields
Observe the safety instructions in section 1.1.2 "Safety Instructions for Working with Strong
Magnetic Fields" [}10].
► Remove the nozzle changer (see 9.2 "Replacing the Nozzle Changer" [}227]).
► During the following inside measurement make sure that the tip of the measuring scale does
not tough the magnetic strip as this might scratch it!
CAUTION

Place a suitable plastic plate between the magnet and measuring scale, if required.
► Position the measuring scale(1) on the top edge of the X axis upper linear guide(2) and
measure the distance to the nozzle changer contact surface(4).
► Hold the measuring scale vertically.
► The setting value (3) is 277+/‑0.2mm.
You can adjust the height, where necessary, by removing or adding NC adjusting plates.

structions:
CAUTION
Installation instructions
► Check the height of the nozzle station (see below).
Fig.309: Setting the height of the nozzle station
(taking the standard nozzle station as example)
► The distance(1) between the contact surface of
the nozzle station and the top edge of the upper
guide rail of the gantry needs to be
266.0+0.1/-0.3mm. You may need to use shim
plates to adjust this.
NOTICE!
Alternatively, you can measure from the top
edge of the lower guide rail of the gantry. In this
case the distance is 105.0+0.1/-0.3mm.
