Elizabeth ★★★★★ Oct 22, 2026

The 47mm depth gives it noticeably more torque than the smaller Nema 17s I’ve used, and the 1.8° steps are dead-on for my CNC setup. Took a bit to mount due to the extra length, but once aligned, it runs smooth and quiet.

Steven ★★★★★ Oct 21, 2026

Wiring this up was straightforward, and the 1.8° step angle gives me precise control without any skipping. The deeper 47mm case definitely adds the torque I needed for my project.

Abigail L. ★★★★★ Oct 20, 2026

The extra 47mm depth made a real difference in torque for my 1.8° steps—no more skipped movements on my Z-axis. Wiring was straightforward, and it runs cool even after an hour of printing.
