Stock-style Voron 2.4 Z endstop contact hardware. This bundle includes a deflanged GT2 20 tooth pulley and a 5 mm x 30 mm steel pin/shaft for the microswitch-style Voron 2.4 Z endstop assembly.

Why this part matters

  • Replaces the small contact hardware used in the Voron 2.4 Z endstop so the nozzle has a repeatable mechanical touch point.
  • The deflanged 20T pulley press-fits into the printed endstop part; the 30 mm shaft sits in the pulley as the Z contact pin.
  • Useful when you lost the original pin, damaged the pulley during assembly, or are rebuilding the stock microswitch-style endstop.

Specifications

  • Pulley: GT2 20 tooth, deflanged for the Z endstop printed part
  • Pin/shaft: 5 mm diameter x 30 mm length steel shaft
  • Fitment: Voron 2.4 stock-style microswitch Z endstop / Z probe contact assembly
  • Included: pulley + pin only

Fitment and pairing

Use this with the printed Voron 2.4 Z endstop parts and the correct microswitch or endstop PCB for your build. The official Voron 2.4 manual shows the Z endstop using a GT2 20 tooth pulley and 5 mm shaft, with the pulley press-fit into the printed part.

If you are moving away from the stock pin-and-pulley style endstop, the Voron 2.4 and Trident Sexbolt Z Endstop Super Kit is the more complete alternate endstop route.

What it is not

  • Not a complete Z endstop kit; it does not include the PCB, microswitch, wiring, printed parts, or screws.
  • Not an XY idler pulley or a general motion-kit pulley; it is prepared for the Voron 2.4 Z endstop contact assembly.
  • If your switch has a lever, remove it only if your Z endstop printed part or PCB assembly requires a bare microswitch.
