The mechanical end stops should never be blocked
during the initial homing function, or during a print.

Adjustment of the Z Axis
A
This step is essential to producing quality
prints with your 3D printer. First, install Cura
LulzBot Edition-the recommended software
for your LulzBot-and connect to the printer as
described in the Cura section of the LulzBot TAZ
manual. Press the
CONTROL
button to open the
Printer Interface
. Use the homing buttons to
H me X
and
H me Y
. When Cura is first launched, a
model should be visible on the work plane. If not, load a
model (STL file) to control your 3D printer. We
recommend the rocktopus, which can be found at
LulzB t.c m/r ckt pus

Do not use the Ho e Z button until after the Z axis end
stop has been adjusted. Verify that the red shipping
cla ps on the Z axis s ooth rods have been reo ved.
Raising the Z Axis
A
Use the
+Z 10
button to move the Z axis up
in 1 0mm increments. Raise the Z axis until the
print head nozzle is approximately 40-50mm
away from the print bed.

B c nt.
If not, in Cura,
turn off the stepper
motors by pressing the
M t rs Off
button.
Turn the threaded rod by
hand on one side of the
printer to raise or lower
that side to match the
measurement on the
other side.
Fine Adjustment of the Z Axis End Stop
Rotate the end stop trigger clockwise to lower
the surface of the thumb-screw by roughly the
same amount as the distance between the
nozzle tip and the print surface. Press the
H me Z
button to home the Z axis. The tip of the
nozzle should be very close to the surface of the bed.

A
Slide a once-folded piece of paper
underneath the nozzle, adjust the Z axis end
stop trigger and home the Z axis through
Cura by pressing the
H me Z
button until
the tip of the nozzle applies pressure on the paper. The
paper should only be able to slowly pulled out with only
slight resistance.

Leveling the Print Bed
B
Move the tool head over to the far right side of the
X axis by using the
+X 100
button in Cura. As the X
axis carriage approaches the end of the X axis, use the
+X 10
button and the
+X 1
button until the tip of the
nozzle is near the front right corner of the bed.
C
Slide the same piece of paper under the nozzle and
home the Z axis. Adjust that bed corner's bed leveling
screws so that the tension felt when moving the paper
under the nozzle matches the tension felt previously.
To raise or lower the front right corner of the bed,
adjust only the screw with the spring. Turn the screw
clockwise to lower the bed, decreasing the tension felt
when moving the paper. Turn the screw counter-
clockwise (raising the corner) to increase the tension
felt when moving the piece of paper under the nozzle.
Once adjusted, press the
+Z 10
button to raise the Z
axis.
D
Repeat the same process, first raising the Z axis,
then using the
+y
button to move the heated bed to
place the nozzle on the rear right corner of the bed.
Adjust the height of the bed using the same procedure
as outlined above. Finally, raise the Z axis and move the
X axis carriage over to the rear left corner of the bed
and perform the same leveling procedure to adjust the
last corner. Close the Control window,
right click
on the work plane and select
Delete All
Objects
.
B
With the Z axis above the bed, use the included
1 50mm ruler to measure the distance from the bottom
of the X axis smooth rod and the top surface of the Y
axis aluminum bed plate on the left side. The distance
measurement should be the same on left and right.
B
Once connected to the printer in Cura, rotate the Z
axis end stop trigger (mounted on the X-axis motor
mount) counter-clockwise to raise the thumb-screw
approximately 1 cm higher toward the Z axis end stop.
C
In Cura, press the
H me Z
button to home the Z
axis. The print head will lower to about 1 cm above the
heated bed. If there's a grinding sound, stop, turn the
printer off and check that the Z axis is level in relation to
the body of the printer (see 1 8b). Manually rotate one of
the Z axis linear threaded rods by hand if needed.
