    • Then slide onto the Lead-Screw a Clamping-Collar - ->- - Rubber-Bushing - ->- - Radial-Bearing.

    • Repeat for the opposite end of the Lead-Screw in reverse order.

    • Adjust the Lead-Screw so there is 13mm protruding from the Stepper-Motor side of the X-Axis.

    • Seat the Radial-Bearings into the insets on the Y-Carriages, slide the Rubber-Bushing against the Radial-Bearings and finally slide the Clamping-Collars so they are against against the Rubber-Bushings.

    • Slightly tighten the Clamping-Collars.

    • Repeat all the above points for Y-Left & Y-Right Axis, like Image 3.

  7. Thrust-Bearings come in 3 parts. Thrust-Bearing-Housing-Washer, Thrust-Bearing-Caged-Roller and Thrust-Bearing-Shaft-Washer The Thrust-Bearing-Housing-Washer and Thrust-Bearing-Shaft-Washer look exactly the same. They are not. The Thrust-Bearing-Shaft-Washer has a smaller internal diameter thus it will be tighter on the Lead-Screw.

  10. Repeat Step 8 for Y-Left & Y-Right Axis
    • Repeat Step 8 for Y-Left & Y-Right Axis

  11. Reattach and reconnect all Stepper-Motors using the previously removed M5-Low-Profile-50mms and 4 x Aluminium-Spacer-40mms On the Stepper-Motor side make sure the Flexible-Coupler grub screw is on the flat portion of the Stepper-Motor shaft.
    • Reattach and reconnect all Stepper-Motors using the previously removed M5-Low-Profile-50mms and 4 x Aluminium-Spacer-40mms

    • On the Stepper-Motor side make sure the Flexible-Coupler grub screw is on the flat portion of the Stepper-Motor shaft.

    • Once in position, tighten the clamping bolt first, then the grub screw.

    • The Lead-Screw side was tightened earlier in this guide.

  12. Attach the X-Axis Limit-Switch to the X-Limit-Switch-Mount using the previously removed 2 x M3-Plastite-Screw-8mm. The M3-Plastite-Screw-8mm's go through the X-Limit-Switch-Mount first, then self thread into the Limit-Switch. A Pozi #1 Screwdriver should be used.
    • Attach the X-Axis Limit-Switch to the X-Limit-Switch-Mount using the previously removed 2 x M3-Plastite-Screw-8mm.

    • The M3-Plastite-Screw-8mm's go through the X-Limit-Switch-Mount first, then self thread into the Limit-Switch.

    • A Pozi #1 Screwdriver should be used.

    • The best technique is to thread into the Limit-Switch a small amount, then back out. Then back in further, back out, so on so fourth until the Limit-Switch is secure.

    • Do not over tighten as you can shatter the switch. Make sure the Limit-Switch is orientated correctly.

    • Insert the previously removed M5-Low-Profile-8mm through the hole on the X-Limit-Switch-Mount and slightly thread on the M5-Drop-In-Tee-Nut.

    • Attach the X-Limit-Switch-Mount to the back of the X-Gantry C-Beam. It should be at the left side if looking from the back. The X-Limit Switch-Mount should be up against the Y-Carriage.

  13. Home the machine and use the jog buttons to move the machine roughly into the middle of the working area. Loosen all the Nut-Blocks on the X & Y-Carriages.
    • Home the machine and use the jog buttons to move the machine roughly into the middle of the working area.

    • Loosen all the Nut-Blocks on the X & Y-Carriages.

    • Loosen the Clamping-Collars that are on the inside of the extrusion channel on the X & Y Axes.

    • Move all Radial-Bearings, Rubber-Bushings & Clamping-Collars away from the plates.

  14. Starting with the X-Axis, thread on the Tensioning-Knob until it is up against the Clamping-Collar. Then loosen the same Clamping-Collar.
    • Starting with the X-Axis, thread on the Tensioning-Knob until it is up against the Clamping-Collar.

    • Then loosen the same Clamping-Collar.

    • Turn the Tensioning-Knob clockwise, you will feel the Lead-Screw tension build.

    • Keep turning until the Stepper-Motor clicks over.

    • Keep turning, just before the point that the Stepper-Motor clicks over is the correct amount of tension for the Lead-Screw.

    • While at this point of tension, tighten the Clamping-Collar that is next to the Tensioning-Knob.

    • Remove the Tensioning-Knob.

    • Repeat all the above for both Lead-Screws on the Y-Axis.

  15. Once all 3 Lead-Screws are tensioned, put back the Radial-Bearings, Rubber-Bushings, and Clamping-Collars that are on the inside of the extrusion channel on the X & Y Axes. The Clamping-Collars only need to be pushed lightly up against the Rubber-Bushings & Radial-Bearings.
    • Once all 3 Lead-Screws are tensioned, put back the Radial-Bearings, Rubber-Bushings, and Clamping-Collars that are on the inside of the extrusion channel on the X & Y Axes.

    • The Clamping-Collars only need to be pushed lightly up against the Rubber-Bushings & Radial-Bearings.

    • We need to release any tension inside the Flexible-Couplers.

    • On the Stepper-Motor side of the X & Y-Axis Flexible-Couplers completely loosen the grub screws and clamping bolts.

    • Then completely tighten the same grub screws and clamping bolts.

    • Make sure you do this to the Stepper-Motor side of the Flexible-Coupler.

    • If you loosen the Lead-Screw side you will loose all tension in the Lead-Screws and you will need to redo it.

    • Tighten all the Nut-Blocks on the X & Y-Carriages. While doing so, squeeze the Nut-Blocks together to remove any backlash.

  16. Home the machine. Then turn the machine off.
    • Home the machine.

    • Then turn the machine off.

    • On the left Y-Axis (The side with the Limit-Switch) measure the distance between the back of the Y-Carriage and Y-End-Plate.

    • On right Y-Axis measure the same distance.

    • Rotate the Flexible-Coupler by hand until it matches the left Y-Axis.

  17. Put back the Lead-Screw-Caps.
    • Put back the Lead-Screw-Caps.
