CAUTION –After selecting Move X,Y, or Z, turning the jog wheel (each click/index) moves the
selected axis (X, Y, or Z) the selected movement amount (10mm, 1mm, or 0.1 mm). Each move
of the jog wheel buffers a movement and can stack up for an unexpected large movement. Until
familiar with the machine response, it’s best to jog the wheel a little, then observe the movement
completion, the jog the wheel again until reaching your target position.
Figure 6.2.5 Selecting to Move Z Axis on LCD Display
6) At this point, jogging the wheel will move the selected axis. Turning the jog wheel clockwise
moves in the positive direction, turning the jog wheel counter-clockwise moves the axis in the
negative direction. Start by jogging the wheel a click or two and observing the movement.
Depending on the selected movement distance, several clicks or even several full turns may be
required to move the axis a desired direction. Any movement overshoot can be corrected by
turning the other way. The total movement amount (from starting position) is indicated on the

In this section, you will load filament to the back of the 3ntr printer or into the MMS Unit. The printer is
delivered with 2 spools of ABS/ASA filament suitable for initial set-up calibration and test prints. For
simplicity, use this material.
NOTE –If only unloading filaments/materials from an extruder that will be left empty, you can select the
“Unload filament” function instead, then subsequently perform a “Purge filament” function from the LCD
Prepare Menu.
CAUTION - Only load filament for materials suitable for the 3ntr A2/A4 printers. If necessary, review the
datasheet or materials profiles within KISSlicer to determine acceptable filament types. If you are
changing the polymer type, you must perform a nozzle cleaning procedure before starting a change
filament procedure.
7.1 Load Filament to Back of Printer
This section details the process to load filament onto the back of the printer.
NOTE - If you are using an MMS unit or Humidity Controlled Container (humidity-controlled container)
the process is different. If feeding material directly from a Humidity Controlled Container or equivalent
container, follow the instructions as applicable (new filament spool is not mounted on printer). With an
MMS unit, follow the applicable portions of the instructions below.
1) Check that there is enough clearance (20-30mm) between nozzle and plate before starting. If
not, move printer plate following instructions for “Move Z axis function”
2) Navigate to the Prepare menu. From the Prepare menu select either the “Change filament” (if
filament was previously loaded) or “Load filament” (if empty) function.
