Mellow LDO NEMA14 36mm High-Temp Stepper Motor | Voron Extruder
Mellow LDO NEMA14 36mm High-Temp Stepper Motor | Voron Extruder
Mellow LDO NEMA14 36mm High-Temperature Stepper Motor
Upgrade your Voron 3D printer's extruder drive system with the Mellow LDO NEMA14 36mm High-Temperature Stepper Motor. Available in two configurations — the compact LDO-36STH17-0354AHG (17mm body) and the more powerful LDO-36STH20-1004AHG (20mm body) — these precision motors are purpose-built for demanding, high-temperature printing environments.
Both variants deliver a robust 10 kg thrust force, ensuring reliable, consistent filament feeding even during extended high-speed print sessions. The high-temperature-rated construction keeps performance stable at elevated operating temps, making these motors ideal for enclosure-based printers like the Voron 2.4 and BLV.
Made in Mainland China.

Frequently Asked Questions
Q: What is the difference between the LDO-36STH17-0354AHG and the LDO-36STH20-1004AHG stepper motors?
A: The main difference is the body length — the LDO-36STH17-0354AHG has a 17mm body, while the LDO-36STH20-1004AHG has a 20mm body. Both share the same NEMA14 36mm frame and 10 kg thrust rating, but the 20mm version is slightly larger and may offer different current/torque characteristics. Refer to the specifications shown in the product images for full electrical parameters.
Q: Are these motors compatible with the Voron 2.4 and Sherpa Mini extruder?
A: Yes. Both the LDO-36STH17 and LDO-36STH20 are specifically designed for use with the Sherpa Mini and Orbiter extruders, which are popular choices for Voron 2.4 and BLV 3D printer builds. They are drop-in compatible with no additional assembly required.
Q: Why choose a high-temperature-rated stepper motor for my 3D printer extruder?
A: Enclosed printers like the Voron 2.4 generate elevated ambient temperatures inside the build chamber. Standard stepper motors can experience reduced holding torque and increased heat soak at those temperatures. High-temperature-rated LDO motors use materials and windings designed to maintain consistent performance in hot enclosure environments, ensuring reliable filament feeding throughout long print runs.
Q: Does the motor come pre-assembled or require any setup?
A: No assembly is required. The motor arrives ready to install directly into your compatible extruder mount. Simply connect the wiring harness to your printer's stepper driver as per your printer's configuration guide.
