¶ Step 1 - Prepare to install the Z- Axis
- Z- Axis Assembly
- 4x M8x30 Cap Head Screw
- 4x M8 Nylon Locking Hex Nut
- 8x M8 Washer
¶ Step 2 - Install the Z - Axis - Part 1
- Make sure the top Z plate is at the top
- Once all four holes are aligned, install an M8 washer on to each M8x30 screw and insert them through the XZ plates, screwing them into the ball screw block
- The top fasteners must be inserted from the front
- The bottom fasteners must be inserted from the back
¶ Step 3 - Install the Z - Axis - Part 2
- Insert an M8 Washer on to each screw
- Thread a Nylon Locking Hex Nut into each Screw and tighten everything
- Double check the orientation of the screws before proceeding:
- The top screws must be inserted from the front
- The bottom screws must be inserted from the back
¶ Step 4 - Prepare the Stepper Motors
- 4x Nema 23 Stepper Motor High Torque
- 12x 40mm Aluminium Spacer
- 4x 35mm Aluminium Spacer
- 4x Coupler - Disk Type
- 12x M5x55 Cap Head Screw
- 4x M5x50 Cap Head Screw
- 4x 3mm Aluminium Spacer
¶ Step 5 - Install the Y Stepper Motor- Part 1
- Coupler - Disk Type
- Insert the coupler on to the end of the Y-Axis Lead Screw
- Tighten the Screw on the Coupler
¶ Step 6 - Install the Y Stepper Motor - Part 2
- 4x M5x55 Cap Head Screw
- Nema 23 Stepper Motor High Torque
- 4x 40mm Aluminium Spacer
- 4x 3mm Aluminium Spacer
- Using a 2.5mm hex key, tighten the marked screw to secure the disc coupler to the NEMA23 shaft
- Rotate the lead screw by hand until the marked screw is accessible. It's required that both Y-Axis lead screw are rotated simultaneously since they are atatched to the X-gantry.
¶ Step 7 - Install the Y Stepper Motor - Part 3
- Tighten the Tensioning Nut until the lead screw is straight
- If you are building a bigger StrongHold ONE then sag on the Lead Screw should be more noticeable, requiring a bit more tension to keep it straight
- Don't overtighten the tensioning nut as it will lead to binding and malfunction of the axis
- Tighten the screw on the tensioner nut once the lead screw is properly adjusted
¶ Step 8 - Install the Y Stepper Motor - Part 4
- Push both Lock Collars against the plate
- Tighten the Lock Collar screw
- Repeat for the Lock Collar on the other end of the Lead Screw
¶ Step 9 - Install the Y Stepper Motor - Part 5
- Repeat Steps 5 through 8 to install the remaining Y-Axis Stepper Motor
¶ Step 10 - Install the X Stepper Motor - Part 1
- Coupler - Disk Type
- Insert the coupler on to the end of the X-Axis Lead Screw
- Tighten the Screw on the Coupler
¶ Step 11 - Install the X Stepper Motor - Part 2
- 4x M5x55 Cap Head Screw
- Nema 23 Stepper Motor High Torque
- 4x 40mm Aluminium Spacer
- Using a 2.5mm hex key, tighten the marked screw to secure the disc coupler to the NEMA23 shaft
- Rotate the coupler by hand until the marked screw is accessible
¶ Step 12 - Install the X Stepper Motor - Part 3
- Tighten the Tensioning Nut until the lead screw is straight
- If you are building a bigger StrongHold ONE CNC then the sag on the Lead Screw should be more noticeable, requiring a bit more tension to keep it straight
- Don't overtighten the tensioning nut as it will lead to binding and malfunction of the axis
¶ Step 13 - Install the X Stepper Motor - Part 4
- Tighten the screw on the tensioner nut once the lead screw is properly adjusted
- Push both Lock Collars against the plate
- Tighten the Lock Collar screw
- Repeat for the Lock Collar on the other end of the Lead Screw
¶ Step 14 - Install the Z Stepper Motor - Part 1
- Coupler - Disk Type
- Insert the coupler on to the end of the Z-Axis Lead Screw
- Tighten the Screw on the Coupler
¶ Step 15 - Install the Z Stepper Motor - Part 2
- 4x M5x50 Cap Head Screw
- Nema 23 Stepper Motor High Torque
- 4x 35mm Aluminium Spacer
- Using a 2.5mm hex key, tighten the marked screw to secure the disc coupler to the NEMA23 shaft
- Rotate the coupler by hand until the marked screw is accessible
