2Pcs NEMA 17 Stepper Motor Encoder Kit, 400PPR Quadrature Rotary Encoder Module for 3D Printer CNC DIY lfx

Upgrade your motion control projects with this 2-pack NEMA 17 stepper motor encoder kit, engineered for makers, engineers, and DIY enthusiasts who demand precise position feedback in 3D printers, CNC routers, robotics, and automation builds. Each kit features a 400PPR quadrature encoder module that delivers 1600 counts per revolution in 4x decoding mode, giving your setup the resolution needed for accurate closed-loop control and reliable step verification. The quadrature A/B channel output supports direction sensing, so your controller always knows exactly where the motor is. Designed to pair directly with standard NEMA 17 stepper motors, the rotary encoder module mounts cleanly and integrates easily into existing CNC and 3D printer setups. Whether you are building a closed-loop extruder, tuning a laser engraver, or assembling a custom pick-and-place machine, this encoder kit provides the consistent feedback that keeps your project running smoothly. What's in the box: 2 x NEMA 17 rotary encoder modules (400PPR, quadrature output). Compact, lightweight, and ready for your next DIY electronics or motion control project.
