System Parameter Configuration (Reference Examples)



For Mach3/4:

Pulses per degree = (Motor steps per rev × Driver microstepping × Reduction ratio) ÷ 360

Example (57mm motor, 16x microstepping, 100:1 ratio): (200 × 16 × 100) / 360 ≈ 888.889 pulses/degree

For Weihong (Syntec) Controls:

Degrees per pulse = 360° / (Motor steps per rev × Driver microstepping × Reduction ratio)

Example (same parameters): 360 / (200 × 16 × 100) = 0.001125°/pulse

Note: User must input parameters based on their actual motor and driver specifications.
