When referring to the front or rear of the machine it is important to know the orientation.

The front of the machine is the end that has the Z-Axis facing it. 

The rear of the machine is where the stepper motors are installed.

The Ball Bearing Nut is installed onto the moving gantry plate. The Ball Nut is secured to the Ball Nut Plate/Bracket.

The Fixed End of the transmission system is on the stepper motor end of the axis. This has the larger FK Bearing.

The Floating End of the transmission system is on the front of the machine. This has the corresponding FF Bearing.

C-Beam is the aluminium extrusion that is 40mm x 80mm and when looking at it front on is in the shape of a “C”.

Other profiles used are 2040 which is 20mm x 40mm and 4040 which is 40mm x 40mm.

It is important to note some other aspects of the machine.

The Diaphragm Coupler is used to connect the ball screw to the stepper motor shaft.

The HGH Bearing is used on the Y-Axis and X-Axis. For machine ease of maintenance, always mount the bearings to have their grease nipples facing out. 

The MGN Bearing is used on the Z-Axis.

There are 2 types of Ball Nut Plate/Bracket in the build. While the X, Y, A/2 axis uses the same Ball Nut Plate/Bracket, the Z-Axis uses a different design. 

The Ball Nut should never be removed from the Ball Screw. 

Each actuator on this build has one FK Bearing (Fixed) and one FF Bearing (Floating).

A. Insert the M4 x 14mm Socket Cap Head Screw through the HGR Rail and thread the M4 Sliding T-Nut onto the end. 1/2 a turn on a Screw will suffice. We will tighten these later.

C. Place one face of a Builder’s Square on the Spoilerboard’s Extrusion, while the other face of your Builder’s Square mates against the Y-Axis’ C-Beam Extrusion and then tighten the screws that secure the Y-End Plate to the front of the machine. 
If you are unsure of what screws to tighten,  please refer to Chapter 3.3.6.

D. Tighten Screws that secure the Bracket L2 to the Front 2040 Extrusion. Please refer to Chapter 3.3.2.   

Important: Ensure to use a reliable Builder’s Square for this process. Using a poor quality tool will negatively impact your CNC’s results later on.    

B. Move the Y-Axis towards the rear of the machine as per the illustration. Ensure to move your Y-Axis as close as you can from the rear of your machine.  

C. Place one face of a Builder’s Square on the Spoilerboard’s Extrusion, while the other face of your Builder’s Square mates against the Y-Axis’ C-Beam Extrusion and then tighten the Screws that secure the Y-End Plate to the rear of the machine. 
If you are unsure of what screws to tighten,  please refer to Chapter 3.3.5.

D. Tighten Screws that secure the Bracket L2 to the rear 2040 Extrusion. Please refer to Chapter 3.3.4.   

Important: Ensure to use a reliable Builder’s Square for this process. Using a poor quality tool will negatively impact your CNC’s results later on.    

B. Move the Y-Axis towards the first middle extrusion as per the illustration.

D. Tighten Screws that secure the Bracket L2 to the rear 2040 Extrusion. If you are unsure of which bracket needs to be tightened, please refer to Chapter 3.3.3.

E. Move the Y-Axis towards the second middle extrusion as per the second illustration. 

F. Tighten Screws that secure the Bracket L2 to the rear 2040 Extrusion. If you are unsure of which bracket needs to be tightened, please refer to Chapter 3.3.3.

The distance acquired with the measurements above should be very similar. Good results are between 1mm to 2mm. If you have achieved better results by measuring the diagonals, you have Squared your machine well. Although if you have found a larger deviation, we recommend redoing chapter 6.2.
