Steps/mm calculator

Lead screw

Timing belt (GT2)

Steps per revolution (= 360deg / step angle)

Microstepping

Screw lead (mm per full revolution)

Result: 1600.00 steps per mm 1 full step = 0.01 mm = 10.00 micron 1 microstep = 0.0006 mm = 0.63 micron

Current per phase (Ampere)

Safety margin (%) - recommended 10-20%

Rsense resistor value (affects A4988 only)
