Apply with sudo sysctl -p.
Before setup, verify your BIOS version. Boot and press Del or F2. Note the version (e.g., RML1316_V1.22). If older than 1.20, update before installing the OS. huayu rml1316 setup best

Our "Best" Recommendation: Set SW1=OFF, SW2=OFF, SW3=ON for 1600 micro-steps/rev (1/8th step). This provides the optimal balance between smoothness, torque, and controller pulse frequency. Your stepper motor will take 1600 pulses to make one full rotation.
The Huayu RML1316 shines with BSD-based firewalls or Linux. For the "best" setup, we outline two scenarios: Apply with sudo sysctl -p
The RML1316 is a bipolar driver. You must identify your motor’s phases using a multimeter (continuity mode). Pairs that beep together are one coil.
The RML1316 can run hot during heavy milling (up to 85°C). For the best longevity:
