![]() ![]() (After reading a bit I see this might not have been the smartest idea. Thus, we can control the stepper motor with just 2 pins from our controller. The DRV8825 is a micro-stepping driver for controlling bipolar stepper motors which have a built-in translator for easy operation. I also adjusted the trimpot on the driver but it made no difference. In this tutorial we will Control the NEMA17 Stepper Motor with DRV8825 Driver Module & Arduino. The DRV8825 driver chip has several safety functions built-in like overcurrent, short circuit, under-voltage lockout, and over-temperature protection. TB6600 Stepper Motor Driver with Arduino Tutorial. The power supply is 12v 3A, so theres sufficient current. This driver can be used with the same code as the A4988 and has a current rating of 3.5 A. Control steppers via a driver board providing STEP+DIR like the ones from Pololu. So the step pulses seem to end up at the motor in some way. A4988, DRV8825 and generic two-pin stepper motor driver library. Half a second later, the coils charged up again, causing a step. I could feel the coils charge up and step, locking the motor, and then when the next step pulse came through the coils "discharged" allowing me to turn the shaft a bit. I grabbed the shaft and tried turning it while it was running, trying to figure out what is going on. So, it moves once every second, even though the step pulses are sent twice a second. The really strange thing is the motor does these steps at HALF the rate of the step pulse. ![]() I have a simple piece of code that sends a step to the motor twice a second. The microstep select (MS1 and MS2) pins of the A3967SLBT are jumper out allowing adjustments to the microstepping resolution. The problem I'm having is the motor moves a step in 1 direction, and then the next step in the opposite direction. 4,6, or 8 wire stepper motors.This EasyDriver provides much more flexibility and control over your stepper motor, when compared to older versions. Maybe the 2 coils pulling against each other? (If thats possible?) The strange thing is the wire order didnt seem to change the symptoms Im having, although I do recall a combination that caused the motor to lock up. Learn how to control a variety of stepper motors using unipolar / bipolar circuits with Arduino. I did however swap some of them out, trying different combinations. Arduino and Stepper Motor Configurations. ![]() I eventually found the correct chart for wiring up the A1, A2, B1 and B2 pins. The only thing I had trouble figuring out was the wires coming in from the motor. I wired everything up according to the drivers specifications. ![]()
