Controlling Bipolar Stepper Motors with Pololu Driver (by Rod Keith)
Does anyone have any ladder logic for bipolar stepper motors using a Pololu driver? I am using a Nema 23 motor on a linear slide. Forward and Return. Nothing elaborate but hard to find help. I am a beginner

If You have to run motor on high speed ld is slow, do You need ramp when start and stop motor.
What kind of input You need for Pololu driver ld generate 5V.

Stepper Driver (by Rod Keith)
Boris I will need 5V or 24 V. Is it possible to have the microprocessor send a DIR and a PUL only to an off the shelf stepper driver?

You can generate 5V pulses and 5V DIR signal You can generate different speed for stepper which You can change with two buttons I will post ld file but I cannot test it I don't have PCB.
DIR is only output ON or OFF
