Using 4 as an example, dividing 7.5 degrees by 4 = 1.875 degrees per step or 196 steps for 360 degrees. Setting the switches divides the step angel, not the number of steps. A 1.8 degree per step motor requires 200 steps for 360 degrees. S1, S2, and S3 are step multipliers for 360 degrees.įor example my motor in the video was 7.5 degrees per step or 48 steps for 360 degrees. Note the three control connections for micro-stepping.

Three of the setup switches select the current limit. It has three control connections (enable, count, direction), four connections for a bipolar stepper motor, and six setup micro switches.
