Before you begin on your journey, a word of caution.
In the comfort of your own home you are about to assemble a robot. This machine can
maim, burn, and electrocute you if you are not careful.
Please do not become the first Lerdge iX victim. There is no special Reddit flair for that.
Please read the entire manual before you start assembly. As you begin wrenching,
please check Lerdge-iX web for any tips and questions that may halt your progress.
For mechanical damage or electrical damage caused by improper operation during the
assembly process, Lerdge Tech does not provide warranty and replacement services.
For the hazards and risks caused by the assembly not in accordance with this assembly
manual, Lerdge Tech does not assume any maintenance or other responsibilities.
Most of all, good luck!

Step 1
Assemble
Aluminum Frame

1.1-Assemble the Z-axis aluminum profile
The screw penetrates
from the side with the
reamed hole
140mm V2040 Aluminum profile
300mm V2040 Aluminum profile
Tips：
Press the aluminum profile on a flat surface (such
as glass, ceramic tiles, etc.) to ensure the accuracy
of the assembly, and then tighten the screws.

1.2-Assemble the Y-axis aluminum profile
The screw penetrates from
the side with the reamed
hole
270mm V4040 Aluminum profile
Tips：
Press the aluminum profile on a flat
surface (such as glass, desktop) to ensure
the accuracy of the assembly, and then
tighten the screws.
Note：
Tighten the screw with moderate force,
over-tightening may cause deformation of
the V4040 profile and affect the
engagement of the Y-axis pulley. Too
looseness may cause the deformation of
frame to during use.

1.3- Frame size requirements
Note:
Please spend your enough patience here. Make sure that the three aluminum profiles that make up the frame are perpendicular to each other as much as
possible, and then use the connection blocks in the next step to further firmly fix the three profiles.
Profiles that are not perpendicular to each other can cause the printed model to appear skewed. Let’s have a good start!

Use 2028 connection blocks to strengthen the
connection between the profiles, which can
further improve the stability of the frame.
The use of customized aluminum alloy
sheets can reinforce the connection between
the profiles, which will further improve the
stability of the frame and ensure the
verticality of the Z-axis profile assembly.

Note：
Please pay special attention to the direction of the plate when assembling the pulleys on plate.
Please make sure the M5 screws are assembled in the correct direction. Reversing the direction
of the screws will cause structural issue for next assembly of the slider.

2.7- Assemble Z-axis motor seat
Button head
mechanical screw
2 x M3*5
Note：
Make sure that the screws are
tightened vertically. Since the
screw is close to the groove of the
aluminum profile, please be
careful not to skew the screw
during the tightening process.
Otherwise, it may cause the Z-axis
motor seat to can’t be firmly fixed.
