• 2 x Hexagon Socket Countersunk Head Screw M4x18

Step 1: Attach the motor to the profile using two M4x18 screws it needs to be secure but do not over tighten.

Step 2: Slide the lead screw into the top of the coupler and tighten the grub screw to clamp it securely in place.

2.3 Install Bowden Tube Connector, XE-axis Assembly and Drive Belt

What you will need

• 1 x XE-axis Assembly
• 1 x X-axis Profile
• 2 x Bowden Tube Connector
• 2 x Hexagon Socket Flat Round Head Spring Washer Combination
• 1 x Drive Belt
• 1 x Wrenches and Screwdrivers

Step 1: Tighten the Pneumatic tube connector firmly into the Extruder using an open-end wrench.

Step 2: Align the bolt head on the XE-Axis Assembly into the hole on the X Axis profile.

Step 3: Secure the XE-axis Assembly to the X-Axis Profile with two M4X16 screws. (Insert the Allen key through the holes on the outer plate).

Step 4: Install the Drive belt round the pulley inside the XE-axis Assembly with the toothed side round the pulley as shown above.

2.4 Install Nozzle Assembly, Z-axis Roller Bracket Assembly

What you will need

• 1 x Nozzle Assembly
• 1 x Z-axis Roller Bracket Assembly
• 1 x Hexagon Socket Flat Round Head Spring Washer Combination

Step 1: Make sure the drive belt is in the profile slot and slide the Nozzle assembly onto the profile as shown above.

Step 2: Attach the Z-Axis Roller Bracket Assembly to the profile, aligning the bolt head into the hole on the profile and using the M4x16 screw into the threaded hole in the profile.

2.5 Install X-axis Tensioner and Connect the Drive belt.

What you will need

• 1 x X-axis Tensioner
• 1 x Hexagon Socket Flat Round Head Spring Washer Combination
• 1 x Hexagon Socket Countersunk Head Screw (black) M4x14

Step 1: Undo the tensioning knob and remove the tensioner block.

Step 2: Thread the drive belt around the pulley making sure it has not twisted and push the pulley back into the tensioner base making the alignment is as shown in the picture above.

Step 3: Screw the tensioning knob back into place by couple of turns.

Step 4: Attach the Tensioner base to the profile Z Axis Roller Bracket assembly with a M4X16 screw on one side and the countersunk screw (in the Tensioner block bag) on the other, both these screws use the same threaded hole in the profile.

Step 5: Secure the ends of the drive belt by sliding the belt into the slots in the Nozzle assembly as in the picture above.

2.6 Install the Z-axis Gantry Assembly and Adjust X-axis and Y-axis Drive belt Tension

What you will need

Assembled Part After Mechanical installation Section 2.5

Assembled Part After Mechanical installation Section 2.2

Step 1: Place the lower V rollers into the grooves on the outside of the Z profiles.

Step 2: Locate the lead screw in the Brass nut on the XE Assembly and turn by hand to screw the gantry down while guiding the other V rollers into the Z profile grooves.

Step 3: Adjust the tension of the X and Y axes drive belts as shown above.

Tips:

Turn the X-axis and Y-axis tensioner knobs to adjust the belt tension.The belts should be taught but not over-tight or too slack. When you press down the drive belt, you should feel some spring in the belt.

If the belts are too lose they can slip during printing ruining the result.

If the belts are too tight they will over stress the pulleys and motors or even break.

2.7 Install the Gantry Profile and Display Assembly

What you will need

• 1 x Gantry Profile
• 1 x Display Assembly
• 4 x Hexagon Socket Head Spring Washer Combination Screw M5x25

Step 1: Fix the Gantry profile onto the upper end of the gantry with four hexagon socket head cap screws M5x25 and tighten securely:

Step 2: Unclip the display from the bracket, slacken the screws pre-installed on the bracket and insert the T nuts into the base profile.

Step 3: Tighten the bolts making sure the T nuts are turning to engage with the base profile.

Step 4: The display can be moved forwards and backwards to suit your preference then tighten the bolts.

Step 5: Connect the ribbon cable to the display screen and clip it back onto the bracket.

2.8 Install Filament Holder, Gantry Cover and Extruder Knob

• 1 x Filament Holder Pipe and Nut
• 2 x 2020 Profile Cover
• 2 x Hexagon Socket Flat Round Head Screw M5x8
• 2 x M5 T Nut
• 1 x Extruder Knob

Step 1: Insert the M5X8 bolts through the holes on the Filament holder upright and loosely attach the T nuts.

Step 2: Align the T Nuts in the top profile groove (The flat side faces towards the back of the printer) and tighten the nuts, the T nuts will turn in the grove as it tightens.

Step 3: Attach the filament holder and secure with the plastic nut.

Step 4: Place the extruder knob onto the top of the extruder motor shaft and push the profile covers in on both sides of the top profile.

2.9 Connect the Bowden Tube to the Extruder

What you will need

• 2 x Joint Claw

Step 1: Press the collar on the extruder Pneumatic Connector in to the fitting and hold.

Step 2: Press the Bowden tube into the connector firmly until it goes no further.

Step 3: Release the collar.

Step 4: Clip the Connector spacer between the collar and the body of the connector to lock in place.

What you will need

• 1 x Power Cable
• 1 x X, E, Z-axis Motor Port
• 1 x X,Z-axis Limit Switch

Step 1: Connect the X, E, and Z-axis stepper motors according to the yellow labels on the 6pin (4 wire) connector. The keys on the plugs must be correctly aligned with the socket first.

Step 2: Connect the X and Z-axis limit switches according to the yellow label on the 3pin (2wire) connectors. The keys on the plugs must be correctly aligned with the socket first.

Step 3: Check the correct input voltage has been selected.
