42BYGH47-401A Nema 17 Stepper Motor

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.

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.

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.
