¶ Step 1 - When to install the Y-Axis belts
- If you are building a Hybrid V-Core 4, the Y-Axis belts must be installed when instructed in the commissioning guide
- If you are building an IDEX V-Core 4, the Y-Axis belts must be installed before following the commissioning guide
¶ Step 2 - Prepare the top Y belts
- Both belts must be pre-cut to your machine size:
- 1110 mm - V-Core 4 300x300
- 1310 mm - V-Core 4 400x400
- 1510 mm - V-Core 4 500x500
- Both belts must have the same length so they can be easily tensioned later.
¶ Step 3 - Prepare the following parts
- 2x vc4_y_belt_body assembly
- 2x vc4_y_belt_clamp
- 4x M3x12 Cap Head Screws
- 6x M3x8 Cap Head Screws
¶ Step 4 - Install the Y belt parts
- Install the vc4_y_belt_body on top of the joiner assembly
- Ensure the belt grooves face the inside of the machine
- 2x M3x12 Cap Head Screws
- Feed the M3x12 cap head screws through the vc4_y_belt_body assembly and tighten them into the threads on the joint plate.
- Repeat the previous step and install the parts on the other Y Joiner assembly.
¶ Step 5 - Route the Top Y belts
- Ensure the belt teeth are facing the stepper motor pulleys.
- Take one end of the top Y belt, and feed it as shown:
- Insert one end in the printed part slot.
- Feed the belt through the tensioner idler making sure the theeth are facing the idler.
- Take the other end of the top Y belt, and feed it as shown:
- Feed the belt through the top stepper motor bearing stacks. Ensuring the belt teeth face the stepper pulley.
- Insert one end in the printed part slot.
- Repeat the previous Steps and install the second Y belt.
¶ Step 6 - Install the Y belt clamp
- vc4_y_belt_clamp
- 3x M3x8 Cap Head Screw
- Install the vc4_y_belt_clamp on top of the vc4_y_belt_body. Insert the screws through the clamp and tighten them into the heat insets on the vc4_y_belt_body.
- Repeat the previous step and install the parts on the other Y belt assembly.
¶ Step 7 - Tighten the stepper motor pullleys
- Please move the gantry back and forth a couple of times to allow the belts to assume their natural positions.
- Tighten the two set screws on the stepper motor pulleys.
¶ Step 8 - Tension the belts
- Adjust both belts tension in a progressive and equal way.
- Do not overtighten your belts! it will result in poor machine performance
¶ Step 9 - Next guide
- If you are upgrading a CoreXY to a Hybrid, you can return to the commissioning guide
- If you are upgrading a Hybrid to an IDEX, or building an IDEX from scratch, continue with the next guide: IDEX Accessories
