Step 1. Assemble the driving wheel carriage.

a. Insert 2 linear bearings into the grooves of the driving wheel carriage.

b. Insert the endstop into the driving wheel carriage. Note the direction of the endstop.

c. Fix the pulley on the stepper motor shaft, with the threaded part up.

d. Fix the motor to the driving wheel carriage with 4xM3*8mm screws and 4 washers (with the connector downwards).

Step2. Assemble the driven wheel carriage.

a. Insert 2 linear bearings into the grooves of the driven wheel carriage.

b. Take the driven wheel shaft. First, loosen the set screws in the pulley and thread the driven wheel shaft through the pulley. Subsequently, attach one ball bearing on each side of the shaft.

c. Insert the assembled pulley into the driven wheel carriage from the back.

Step3. Assemble the extruder carriage.

Insert the remaining 4 linear bearings orderly into the extruder carriage.

Step4. Connect the X axis.

First, fit the two X axis rods through the linear bearings on the extruder carriage.

Then insert one end of the two X axis rods into the corresponding holes of the driven wheel carriage.

Finally, insert the other end of the two rods into the holes of the driving wheel carriage.

Note:

1. Note the direction of the 3 carriages, the belt grooves on the extruder carriage must be aligned with the pulleys on the driving wheel and the driven wheel carriage.

2. If the holes are not perfectly fit, please trim them with a file.

3. It is suggested that you use soft headed hammer to hit the two ends of the rods, making sure that the rods are fully inserted into the holes.

Step 3: Mount Y Axis Front and Rear Rods

Required parts Required number Part ID

Y axis rod*2 NO. 3

Locking ring*4 NO. 6

Pulley *5 NO. 32

Belt loop*1 NO. 34

The following part shows how to assemble Y axis front and rear rods.

Y axis Front rod :

a. Prepare the rod

Y axis front rod: locking ring—pulley—Pulley—locking ring

b. Fit the rod into the ball bearings of the right side panel and left side panel. Fasten the locking ring.

Y axis rear rod:

a. prepare the rod

locking ring—pulley—pulley—belt loop—pulley—locking ring

Note: Pay attention to the direction of each pulley，the two pulleys are in opposite directions.

b. Put the belt loop to the right end of the rod with two pulleys.

c. Fit the rod into the ball bearings of the right side panel and left side panel. Fasten the locking ring.

d. Loop the belt around the pulley on the rod and the Y axis motor. Make sure the two pulleys are aligned.

If the belt is too loose or too tight, you can adjust the placement of the Y axis motor.

Step 4: Connect Y Axis Left and Right Rods With X Axis

Required parts Required number Part ID

Y axis rod *2 NO. 1

Locking ring*2 NO. 6

Insert the Y axis rods orderly through the holes on the rear panel, 2 locking rings (one for each rod), the linear bearings on X axis driving wheel carriage and driven wheel carriage, until they reach the Y axis rod fixed panel on the front panel. Fasten the locking rings.

Connect the Y Axis left rod with the driven wheel carriage.

Connect the Y Axis right rod with the driving wheel carriage;


Step 5: Assemble Z Axis

Required parts Required number Part ID

Z axis rod *2 NO. 4

Locking ring*2 NO. 7

Ball bearing*1 NO. 29

Z axis threaded rod *1 NO. 52

M3*12mm screw*4 NO. 16

M3 Washer*4 NO. 5

Step 1. Respectively fit the two Z axis rods into the two corresponding holes on the upper panel, two locking rings, the two linear bearings on the hotbed from the top down, until they reach the Z axis rod holder on the lower panel. Fasten the locking rings.

Step 2. Insert the Z axis threaded rod spirally from the bottom up into the corresponding hole on the lower panel, through the Z axis nut on the hotbed and a ball bearing, until the threaded rod reaches the Z axis bearing fixed panel on the upper panel.

Step 3. Fix the motor tightly with 4xM3*12mm screws and 4 washers. (Fasten the screws in a diagonal direction.)

Step 6: Mount X Axis Belt

Required parts Required number Part ID

Beltx1 NO. 33

Timing belt platex 1 NO. 39

Step1. Loosen the 4 screws on the X axis stepper motor slightly. Loop the belt around the pulley on the driving wheel carriage from inside to outside.

Step 2. Pull the belt from bottom up across the pulleys on the driven wheel carriage.

Step 3. Pull both end of the belt to the extruder carriage.

Fix the two ends of the belt into the groove on the extruder carriage respectively. Cut the spare belt. Keep the two ends of the belt are in alignment. Fasten the two ends tightly into the groove with the timing belt plate.

Step 4. Tighten the screws on the stepper motor.

Note: Pull the belt tightly and properly to make sure it does not slid or jump gear.

Step 7: Mount Y Axis Belt

Required parts Required number Part ID

Belt*1 NO. 33

Belt spring*2 NO. 23

Step1. Assemble the belt on Y axis right side rod:

a. Loop the belt down- top around the pulley of Y axis front rod and insert the end into the groove on the driving wheel carriage.

b. Pull the belt to the pulley of Y axis rear rod, loop the belt from top -down around the pulley.

c. Taut the belt, fit the belt spring on the middle of the upper belt.

Note: At first, move the X axis to the middle of the building platform. Subsequently, fit the belt ring on the upper belt approximately in the middle of the belt.

d. Insert the other end of the belt into the groove of X axis driving wheel carriage. Use a pair of scissors to cut the belt in a proper way. Fasten the set screws of the front and rear pulley. Please make sure that the two pulleys are parallel and in line with each other.
