Project Dashboard TAZ 6 TAZ 6 Final Assembly Workflow

1 Inspecting the Frame Assembly

Obtain a completed TAZ6 Frame Assembly (AS-PR0006)

Place the completed frame on the granite block and verify that it sits flat and and doesn’t teeter, like a chair with one short leg.

Line up the square along both ends, perpendicular to the length of the frame, as pictured.
Examine the relationship between frame and square. If at any point the gap meets or exceeds 2mm, the frame must be rejected for re-squaring.

Firmly grasp each drive rod and check for movement between the upper and lower bearings by attempting to move the drive rod up or down. Both drive rods must be incapable of vertical movement. Visually verify that the drive rod has been fully seated in both bearings.
If any vertical movement is possible (without flexing the Z-Upper) or the bearing is not fully seated, the frame must be rejected.
The frame must be re-squared after proper tension is achieved.

Verify that the vertical smooth rods are flush with the Z-Upper and that the set screws in the Z-Lowers have been torqued to 3 in*lbs.

If all criteria have been met, carefully place the frame on your workbench.

2 Attach Z-Couplers to Motors

Gather parts:
2x NEMA 17 Stepper Motor, Moons' - EL-MT0029
2x Helical Flexible Shaft Coupling with Set Screws HD-MS0351

Required Tools:
1.5mm Hex Driver
16mm Z-Motor Jig
5in*lbs Torque Driver w/ 1.5mm Hex Bit installed

Attach couplers to both Z-Motors;
Locate the flat side of the motor shaft. To make alignment easier, rotate the flat side of the motor shaft towards your dominant hand.
Slide the coupler over the motor shaft.
Space the distance between the coupler and the top surface of the motor with the printed 16mm Z Motor Jig.
Using the 1.5mm Hex Driver, tighten one of the lower set crews of the coupler to the flat side of the motor shaft.
It is crucial that the first set screw to be tightened is aligned with the flat side of the motor shaft.
Tighten the other lower set screw, and torque both to 5in*lbs.

Parts & Tools
Identify flat side of motor shaft and rotate towards dominant hand
Tighten first set screw to flat side of motor shaft

3 Attach Z-Motors to Z-Motor Mounts

Gather parts:
2x Moons’ Motors with couplers attached – EL-MT0029 & HD-MS0351
4x M3x10 BHCS – HD-BT0148
4x M3 Black Washers – HD-WA0038

Required tools:
2mm Straight Tip Hex Driver
1.5mm Hex Driver
5in*lbs Torque Driver w/ 1.5mm Hex Bit installed

Attach motors to Z-Lower of frame;
Lifting that side of the frame off the workbench, slide one motor underneath with the connector facing inwards, as pictured.
Slide the coupler onto the lower end of the drive rod.
Place M3 Black Washers onto each M3x10 BHCS and begin threading, but do not tighten yet.
Alignment of the motor shaft to the drive rod is easiest determined by the straightness of the coupler.
Position the motor on the Z-Lower so that the coupler remains straight and tighten all four M3x10 BHCS securing the motor to the motor mount once proper alignment has been achieved.
A good indicator is if the slots of the coupler remain the same size, larger or smaller gaps indicate an alignment issue.

Repeat for the other Z-Motor, ensuring that the connector for the motor is oriented inwards, towards the center of the frame, and that the coupler is straight once the motor has been tightened to the Z-Lower.

Tighten coupler’s set screws to drive rod end;
While rotating the drive rod by hand, observe near the top of the coupler to locate the flat side of the drive rod’s lower end.
Tighten one of the coupler’s upper set screws onto the flat side of the drive rod, before tightening the other. Torque both to 5in*lbs.
Repeat for the other side.

4 Apply Rubber Feet to Frame

Gather parts:
4x Black Adhesive-Back Bumper, Square - HD-MS0336

Carefully lay the frame on its back.
Apply one Rubber Bumper to each end of the lower horizontal extrusions of the frame.
Do not cover the open slots of the vertical extrusions, refer to image.
Ensure that the rubber feet are straight and don’t hang over the edge of the extrusion towards the inside of the frame as they can be ripped off by packaging materials.

Stand the frame up, but rotate so the back is facing you.

Line up carefully and press firmly with thumb

5 Install X-Axis Smooth Rods

Gather Parts:
1x X-Carriage Assembly – AS-PR0032
2x 12mm X 515mm Stainless Steel Smooth Rod – HD-RD0047
4x M3x6 Set Screw – HD-BT0012

Required Tools:
1.5mm Hex Driver
2in*lbs Torque Driver w/ 1.5mm Hex Bit installed

First we must ensure both ends of the X-Axis are at the same height.
To do so, you will measure with a ruler from the top of the Z-Nut to the top of the Z-Upper, as pictured.
Set both sides to the same height by rotating the drive rod by hand.

Begin inserting the 12mm Smooth Rods into the Z-Carriage Motor End, which should be to your right.
Slide them through about half way.
Slide the X-Carriage onto the Smooth Rods, with the bearings facing towards you, double bearing on top.
Slide the Smooth Rods the rest of the way, into the Z-Carriage Idler, until flush with the outside of the idler end.

Insert two M3x6 Set Screws in each Z-Carriage.
On the Motor end they are located on the rear, on the Idler end they are located on the front.

6 Adjust Z-axis

At this point we want to take a few steps to ensure the Z-Axis will operate smoothly. This action will be performed on both sides before proceeding.
Using your hand, attempt to rotate the drive rod in both directions.
Does it rotate easily?
Are both screws securing the Z-Nut to the Z-Carriage tight, but not over-tight?

If answered no to either question, loosen both M5 screws securing the Z-Nut using a 4mm Ball Tip Hex Driver.
While rotating the drive rod by hand, gradually tighten the rear Z-Nut Mounting screw until the drive rod begins to get harder to turn.
Now gradually tighten the front one while rotating the drive rod by hand until you reach the “sweet spot” where the drive rod becomes easy to rotate by hand.
Perform the same adjustment to the other side, and you should be good to go!

7 Tighten Bearing Holders & Install X-Axis Drive Belt

Gather Parts:
1x GT 2 Single Sided Neoprene Belt - 1164mm by 6mm – HD-BL0032
2x M3x12 SHCS – HD-BT0039
2x M3 Black Washers – HD-WA0038

Required Tools:
Cordless Electric Driver w/ 2mm Hex Bit installed, torque setting ~3
2.5mm Ball Tip Hex Driver

Using the cordless driver, tighten both bearing holders to the X-Carriage.

After tightening, verify that the X-Carriage slides smoothly from end to end.

Cut a Belt (HD-BL0032) at an angle, this will help it feed through the Idler end easier.
Apply M3 Black Washers to both M3x12 SHCS (HD-BT0039 & HD-WA0038)

Place the end of a belt in the left clamp of the X-Carriage, teeth facing up, with the end of the belt facing left.

The belt position in the left clamp impacts how the belt rides in the Idler bearings during axis motion;
If the belt is placed too far into the clamp it can cause the belt to ride towards the front of the Idler and rub on the plastic. A belt in this position will often rub against the single bearing holder as well and may cause the belt to slip under tension due to not enough grip on the belt.
If the belt is not in the clamp far enough it tends to ride towards the rear of the Idler bearings and rub against the plastic. The belt should not rub against plastic at any point of axis motion.
A good way to check this alignment before tightening the belt is to slide the X-Carriage towards the idler. The front edge of the belt (currently farthest from you) should line up roughly with the center line between the two bearings of the Idler. See picture for reference.

Secure the belt in the left clamp with one M3x12 SHCS (with washer).
DO NOT over-tighten! The belt clamps on the X-Carriage break easily when over-tightened. Do not attempt to make the tongues of the belt clamp touch, a small gap should remain.

Flip the belt over the clamp counter-clockwise, and feed the end of the belt through the Idler, starting from the top with the teeth facing down.
Pull the remaining length through the Idler and loop around the X-Motor pulley.

Place the belt over the right clamp on the X-Carriage and bend counter-clockwise to enter the clamp.
Line up the belt’s position in this side of the clamp with the belt’s position in the left clamp.
Install one M3x12 SHCS (with washer) but do not tighten.
Grip the excess length of the belt protruding from the right clamp with the pliers, as close to the clamp as possible.
While holding grip with the pliers, rotate to apply tension to the belt.
Tighten the M3x12 SHCS installed previously to secure the belt with tension applied.
Use the Gates Sonic Tension Meter to dial in belt tension to 23-27 Newtons, several adjustment attempts may be necessary before proper tension is achieved.

Once tension on the belt is properly set, cut off the excess belt from both sides of the clamp but leave about 10mm protruding. This allows for grip should the belt tension need adjusted post-assembly.

By hand, move the axis from end to end and make sure movement is still smooth throughout. Also watch the belt's position on the Idler bearings as you move the axis to ensure that no friction contact occurs with any plastic parts.
