9.1 Hardware Maintenance
9.1.1
Care of the Vertical Axis
The linear profile of the vertical axis
should be wiped briefly with an oil-
moistened cloth (conventional machine
oil) along its entire length after each
use of the printer so that a thin film of
oil forms on the metal. This effectively
prevents dirt or rust from accumulating
on the rail or slide over time.
9.1.2
Care of the Toothed Rack
The gear rack should never be
greased, as the grease presses into
the rear flanks of the teeth and can
have a very negative effect on the
clean running of the gear wheel.
Instead, clean the rack from time to
time - especially in the area of the rear
flanks - with a thin wooden stick or
cloth and oil the rack thinly with an oil-
soaked cloth (conventional machine oil)
to prevent rust.
9.1.3
Care of the Linear Slide
The linear slide is a high-precision system in which 4 chains of ground steel balls run to
guide the slide on the profile. The system must be greased after a running distance of
2000 km or after 12 months - whatever comes first - to avoid abrasion and friction and
to ensure smooth running. Only use the grease supplied by wallPen and the grease gun
supplied.
It is best to grease the system when the printer is disassembled. This is the best way to
reach the screw for the grease nipple and to apply the grease gun stably.
