• Assemble all the Solid V Wheels as per the drawing.
• It can help to use one of the longer screws to align everything by threading the parts one by one.

• At this step, the Y Gantry will be assembled. Please note that the Y-Axis Gantry Plate has 7 holes for 7 M5x30mm Screws and the holes placed on the lower part of the plate. those lower holes are to be used with Eccentric Spacers – 8mm Hex – 6mm Height. These Eccentric Spacers make it possible to adjust the pressure between wheels and V-Slot.
• All quantities are for both sides of the Y-axis.
• Precision Shims are encountered in the wheel kit.

Step 3 Insert the M5x30mm screws into the Y-Axis Gantry Plate and layer the hardware as per the drawing above.

Step 4 Repeat this process for the other Y-Plate.

• This section will cover the spring-loaded system for the motor. This system was designed to keep the right tension between the rack and the pinion.

Step 5 Start placing the M5x25mm and M5x27 screws on the Y-Plate and built it up as per the following image.

• IMPORTANT The right amount of tightening in the M5 Nylon Insert Hex Locknut and M5x25mm Screw is when the motor plate became hard enough to be hand turned. This means that this nut should not be over-tight or under tight. Before tightening this part, ensure that you place the motor plate quite close to its final position.

Step 6 Assemble the spring-loaded mechanism as per the image.

That is what you should have achieved so far.

• This section will show how to attach the pinion and motor to the Y-Axis Gantry.

Step 7 Slightly tight the pinion to the shaft of the motor.

Step 8 Tight the motor on the plate using the 4 x 12mm M5 Low Profile Screws.

Step 9 Adjust the centre of the pinion to match the centre of the Wheels and tight the pinion using the long side of your Allen-Key.

• Please Note That it might be hard to find a spot to reach the screw with your Allen-Key. If this happens, you tight as much as you can with the pinion in the right position, undo Step 10, tight the pinion and attach the motor back accordingly to the previous drawing.

Please compare your assemble against the following drawing of Y-Axis right side

Please compare your assemble against the following drawing of Y-Axis left side

• At this stage, you should be ready to start the X/Z gantry which will be covered in this chapter.

Step 10 Attach the spacer blocks by lining up the spacer blocks with the bottom of the OX Z Flate Front

Step 11 Insert the 10mm screws into the smaller holes on the plate and the threaded holes in the spacer, the larger holes will line up with the between the spacers and the plate for the wheels in the next step.

Step 12 Using 3 x 45mm M5 Low Profile Screws screws attach the V-Wheels through the Gantry Plate and the Spacer Block (V-Slot).

Step 13 Use 3 x Eccentric Spacer - 8mm Hex - 6mm Height on one Spacer Block (V-Slot) and 3 x Metric Aluminum Spacers 6mm on the other.
