The mechanical endstops should never be blocked
during the initial homing function or during a print.

Adjustment of the Z Axis
A
Take the time to go through the leveling
procedure to help ensure that your prints are
consistent and trouble free. Install the Printrun
software and connect to the printer as described
in the Printrun software section in the complete TAZ 3D
printer manual. Use the homing buttons to home the X
and Y axis.
15
Do not use the Home Z button until after the Z
axis end stop has been adjusted. Make sure you
have removed the red shipping clamps on the
Z axis smooth rods.
Raising the Z Axis
A
Use the +Z 10 button to move the Z axis up
in 10mm increments. Raise the Z axis until the
hot end nozzle is approximately 40-50mm away
from the print bed.
16
B
With the Z axis above
the bed, use the included
150mm 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.
If not, in Pronterface, turn
off the stepper motors by
pressing the
Motors Off button. Turn the threaded rod
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 screw counter-clockwise to raise the
surface of the thumb-screw by roughly the
same amount as the distance between the
nozzle tip and the print surface. Press the
Home Z button to home the Z axis. The tip of the nozzle
should now be very close to the surface of the bed.
17
A
Slide a piece of paper underneath the
nozzle, adjust the Z axis end stop and home
the Z axis until the tip of the nozzle applies
firm pressure on the paper. You should be able
to slowly pull out the sheet of paper with only slight
resistance.
18
Leveling the Print Bed
B
Move the hot end nozzle tip over to the far right side
of the X axis by using the +X 100 button. As the X axis
carriage approaches the end of the Y axis, use the +X 10
button and the +X1 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 the 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.
B
Adjust the Z axis end stop trigger on the far left of the
printer, mounted on the X-axis motor mount. Once
connected to the printer in Pronterface, rotate the Z axis
end stop trigger counter-clockwise to raise the thumb-
screw approximately 1cm toward the Z axis end stop.
C
Press the Home Z button to home the Z axis. The hot
end will lower to about a centimeter 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. Manually rotate one of the Z axis linear
threaded rods by hand if needed.
