LDO-36STH20-1004AHG(DFH)

LDO high-temperature NEMA 14 pancake stepper for compact direct-drive extruders. The 36STH20-1004AHG(XH) is the LDO Motors 1.8° pancake motor used where a small, heat-tolerant extruder motor matters more than frame size.

Why this motor

• High-temperature build: LDO specifies Class H insulation for operation up to 180°C, with materials selected for heated 3D-printer environments.
• Compact extruder format: NEMA 14 pancake body with a 20 mm motor length for tight toolhead packaging.
• Integrated drive gear: KB-3D’s spec lists a 2.5 mm shaft with integrated 10-tooth gear, the format commonly used in compact extruders.
• Ready wiring: integrated 1 m high-temp Teflon lead with JST-XH termination.

Intended use

Use this as a compact extruder motor for Voron-style direct-drive toolheads and similar builds that call for the LDO 36STH20-1004AHG family, including Clockwork 2 / Stealthburner, Galileo, Orbiter-style and other tight extruder packages when the BOM matches this motor.

Compatibility notes

• Match the connector pinout and gear requirement against your extruder BOM before installation.
• This is a stepper motor, not a complete extruder kit and not a stepper driver.
• Use a current-capable stepper driver such as the live BTT TMC2209 v1.2 Stepper Driver or BTT EZ2209 Stepper Motor Driver where your control board supports it.
