NEMA 17 and NEMA 23 steppers optimized for smooth microstepping and precise extrusion control.
In 3D printing, motor performance directly affects print quality. Low-quality motors with uneven magnetic pole spacing cause "VFA" (vertical fine artifacts) — a pattern of faint banding visible on smooth surfaces. This is why premium printer manufacturers (Bambu Lab, Prusa, Voron community) specify motors by both torque and inductance.
Lower inductance motors (2–4mH range) respond faster to current changes, enabling smoother microstepping at higher speeds — important for input shaping in fast printers. Higher inductance motors step more quietly at low current but run warmer at high-speed printing.
NEMA 17 motors for X/Y axes (lightweight, fast) and NEMA 17 or 23 for Z and extruder. Look for low inductance (2–4 mH) for high-speed CoreXY printers.
NEMA 23 motors for larger build volumes where NEMA 17 torque is insufficient. Dual Z-axis NEMA 23s prevent bed tilt on larger machines.
Short-body NEMA 17 steppers (25–35mm stack) for direct-drive extruders where weight matters. Low detent torque for smooth pressure-advance performance.
The Voron community recommends 0.9° (400-step) motors for XY and 1.8° for Z and extruder. We recommend our 17HS2408-D at 0.59 Nm for XY axes and the 17HS1352-P1 for the extruder. Both are wired as bipolar parallel for maximum torque at speed.
Noise comes from resonance at certain step frequencies. Solutions: use 1/16 or 1/32 microstepping, upgrade to TMC2209 (StealthChop mode), or switch to 0.9° motors which resonate at different frequencies. Lower inductance motors also tend to run quieter with modern drivers.
