Gather Materials

2 Prepare the Z Lower Left

Place 1x LDO geared stepper motor [EL-MT0084] inside the Z lower left motor jig, then slide 1x 16 teeth timing pulley [HD-MS0033] on the motor shaft making sure one of the set screws on the pulley is aligned with the flat side of the motor shaft.

While pushing down on the timing pulley torque the set screws to 3 in*lb.

Using the bearing punch and 1x rubber sealed bearing [HD-MS0411] and Z lower left [PP-GP0697] press the bearing into the Z lower left.

Then align the motor with the Z lower left so that the connector is on the opposite side as the smooth rod holes.

Before fully sliding the motor into the Z lower left, feed 1x GT2 Belt [HD-BL0023] through the hole between the two smooth rod holes and loop it around the timing pulley.

Then push the motor so that the shaft goes through the bearing while making sure the connector is on the opposite side of the smooth rod holes.

Once the motor is placed inside the Z lower left secure using 4x M3x10 BHCS [HD-BT0148] with M3 washers [HD-WA0038].

Now using 1x YZ idler [PP-MP0225], 1x M5x20 SHCS [HD-BT0151] and 2x rubber sealed bearings [HD-MS0411] assemble the YZ idler around the end of the belt making sure the motor is on the opposite side of the motor.

Secure the timing pulley to the motor
Make sure the Z lower left is flat
Use the bearing punch to press the bearing into the Z lower left
Place the motor inside the Z lower left with the belt around the timing pulley
Use 4x HD-BT0148 w/ HD-WA0038 to secure the motor
Install YZ Idler making sure the head of the bolt is on the other side of the motor

3 Prepare the X Motor Mount

Place 1x NEMA 17 stepper motor [EL-MT0068] inside the Z lower left motor jig, then slide 1x 16 teeth timing pulley [HD-MS0033] on the motor shaft making sure one of the set screws on the pulley is aligned with the flat side of the motor shaft.

While pushing down on the timing pulley torque the set screws to 3 in*lb.

Using the bearing punch and 1x rubber sealed bearing [HD-MS0411] and X motor mount [PP-GP144] press the bearing into the X motor mount.

Check that the bearing is secure inside the X motor mount by knocking the motor mount on the table and the bearing should say in place, if it falls out set part a side and notify the line lead. Do not slam part on table or the part may break!

Place 2x M3 lock nuts [HD-NT0001] inside the two nut traps in the X motor mount. Then using 2x M3x20 SHCS [HD-BT0007] with washers [HD-WA0038] secure the lock nuts. Make sure to leave screws loose..

Then thread 2x M3 set screws [HD-BT0012] into the two brass inserts on the left and right side of the motor mount.

Now attach the switch [EL-SW0022]to the motor mount using 2x M2x10 SHSC [HD-BT0107] with washers [HD-WA0012]. Make sure the button is on the side closest to the motor.

Attach the motor with timing pulley to the motor mount using 3x M3x10 SHCS [HD-BT0148] with washers [HD-WA0038]. Make sure the motor connector is facing the switch.

Thread 2x HD-BT0012 into the two brass inserts on the left and right side
Attach the limit switch making sure the button is by the motor mount
Attach the motor to the X motor mount using 3x HD-BT0148 with HD-WA0038

4 Prepare the Z Upper Left

Take the Z upper left [PP-GP0358] and place it on the Z upper top plate [PP-FP0156] making sure the square hole aligns with the three holes in the Z upper top plate.

While holding the two parts together flip them over so that the Z upper top plate is on top, then secure them together using 4x M3x10 FHCS [HD-BT0116].

Now take the switch [EL-MS0022] and place it on the table as shown in [reference#1] then take the base of the switch and bend it upwards so the tabs are bent to 90 degrees.

Verify that the button is on the left side when the tabs are on the top and pointing up. If the button is on the right bend the tabs the other way.

Now slide 2x M2x10 SHCS [HD-BT0107] with M2 washers [HD-WA0012] through the side of the switch that the tabs pointing.

Then fasten the switch to the Z upper left.

Place the Z upper left on top of the Z upper top plate
While holding both parts flip them over and secure them together
[reference#1] Prepare the switch with 2x HD-BT0107 with M2 washers
Install the switch to the Z upper left

5 Assemble the Z Axis Left

Using the reaming tool, ream both smooth rod holes on the Z lower left.

Then slide 2x smooth rods [HD-RD0061] into the smooth rod holes.

Now take the X motor mount and slide it onto the smooth rods making sure the motor is on the opposite side of the flat side of the Z lower left.

Take the Z upper left and slide it onto the end of the smooth rods with the flat side on the same side as the flat side of the Z lower left.

Then pull the YZ idler up to the Z upper top plate and attach it using 1x M5x12 BHCS [HD-BT0158] with a M3 washer [HD-WA0040]. Then install the 2x M3 set screws [HD-BT0012] in the two holes next to the idler.

While sliding the X motor mount along the smooth rods tighten the two screws that are on the backside of the motor mount to secure the bushings.

Then take the belt anchor [PP-GP0394] and using 4x M3x10 BHCS [HD-BT0148] attach the belt to the X motor mount.

Ream the two smooth rod holes on the Z lower left
Slide both smooth rods into the Z lower left
Slide the X motor mount onto the smooth rods
Slide the Z upper left onto the smooth rods
Pull the belt towards the Z upper top plate
Attach the YZ idler to the Z upper top plate
Install set screws
While sliding the X motor mount on the rods tighten bushing
Attach the belt to the motor mount
Done! Take me home
