LDO-42STH25-1004CL200E(VRN) NEMA17 Linear Stepper Motor 200mm Tr8x8 for Voron V0 Z Axis

The LDO-42STH25-1004CL200E(VRN) is a compact 1.8° NEMA17 linear stepper motor designed for precise Z-axis motion in small-format CoreXY and DIY 3D printers. It features an integrated 200mm Tr8x8 lead screw, a short 26mm motor body, and a PEEK anti-backlash nut for stable, repeatable vertical movement.

This motor is commonly used as the Z motor for Voron V0 / V0.1 / V0.2-style builds, where a compact footprint, reliable lead screw motion, and clean wiring are key. LDO documentation also lists this model as the official Z motor in Voron V0.2-S1 BOM references.

Key Features

Compact 26mm NEMA17 Body

With a 42.3mm max frame size and 26mm max body length, this motor is built for tight printer assemblies where standard NEMA17 motors may interfere with panels, motion parts, or enclosure space.

Integrated 200mm Tr8x8 Lead Screw

The motor uses a 200 ±1mm Tr8x8 lead screw with P2 × 4-start thread geometry, making it fast and stable Z-axis travel in compact 3D printer platforms.

PEEK Anti-Backlash Nut Included

The black PEEK anti-backlash nut helps reduce axial play in Z-axis movement, improving layer consistency and repeatability compared to a basic lead screw nut.

1A Phase Current with Class B Insulation

Rated at 1.0A per phase, with Class B 130°C insulation, this motor is suitable for enclosed printer environments when configured with proper stepper current and thermal management.

This motor is suitable for:

• Z-axis applications on Voron V0 / V0.1 / V0.2
• Compact DIY 3D printers that use a NEMA17 integrated lead screw Z motor
• Builds requiring a 200mm Tr8x8 lead screw
• Printer designs using anti-backlash Z-axis motion
• Small enclosed printers where a 26mm short-body motor is preferred

This model is commonly listed as a Z motor for Voron V0.1 / V0.2, with 1.0A phase current, 26mm body length, and a 200mm Tr8×8 output shaft.

Before ordering, confirm your printer requires a 200mm Tr8x8 lead screw, NEMA17 31mm mounting pattern, and a compatible connector / wiring layout.

Installation Notes

Match the coil pairs correctly before connecting to the stepper driver.

Set motor current according to the 1.0A per phase rating.

Do not over-tighten the M3 mounting screws - the drawing specifies a minimum thread depth of 3mm.

Keep the lead screw clean and properly aligned to avoid Z binding.

Confirm nut orientation and lead screw travel range before powering the printer.
