Overview

The LDO-42STH48-2004AC(VRN) is a 1.8° NEMA17 stepper motor designed for Voron V1.8 and Voron V2 Z-axis applications. It uses a 48mm motor body, 5mm output shaft, 2.0A rated phase current, and 59N·cm holding torque, making it suitable for stable Z motion in CoreXY 3D printer builds.

This motor is commonly listed in LDO Voron V2.4 BOMs as the Z motor, with 4 pcs used in Voron V2.4 builds and 2–4 pcs used depending on Voron V1/V2 configuration.

Key Features

Voron Z-Axis Ready

Built for Voron V1.8 and V2 Z motion systems, this motor is intended for lifting and leveling the gantry/bed system with consistent torque and predictable step response.

48mm NEMA17 Body with 59N·cm Torque

The 48mm motor length provides stronger holding torque than shorter NEMA17 motors, helping maintain stable Z positioning under printer frame and gantry load.

2.0A Phase Current for Reliable Motion

Rated at 2.0A per phase, this motor is suitable for 3D printer control boards and stepper drivers commonly used in Voron builds. Configure driver current according to your board, cooling, and firmware setup.

Preconfigured Cable & Connector Layout

The motor uses a PH-6 motor-side connector and a 700±20mm cable with JST XHP-4 or equivalent connector, reducing wiring work during Voron assembly.

Compatibility

Compatible with:

Voron V1.8 Z-axis

Voron V2 / V2.4 Z-axis

Custom CoreXY 3D printer Z-axis systems using 42mm NEMA17 motors

Builds requiring a 5mm shaft, 31mm NEMA17 mounting pattern, and 2A-class stepper driver support

LDO documentation lists LDO-42STH48-2004AC(VRN) as the Z motor in Voron V2.4 BOMs, while merchant listings also identify it as part of LDO Voron motor kits for Voron Z-axis use.

Installation & Use

Installation Notes

Confirm coil pairs before connecting to the stepper driver.

Set motor current based on your control board, driver model, cooling, and firmware configuration.

Use 2–4 motors depending on your Voron Z-axis layout.

Do not force the PH-6 connector; check orientation before plugging in.

This is a plain shaft motor, not an integrated gear motor.
