Re: Stepper driver help
Such a small stepper can easily be controlled by our common pololu / stepstick drivers. (A988 or DRV8825 are common ) All you'd need is an arduino nano on a breadboard, a driver,a potmeter or encoder...

As Olaf says, you can use a standard low cost driver with that motor. Be sure to adjust the current on the driver to be below the 0.4A rating of your motor. A 12V power supply should be sufficient and...

Okay so if I understand correctly will these parts be sufficient? I am unsure what the potentiometer or the end stop is for. I was hoping to just have a momentary switch for clockwise and another for...

The stepper driver looks OK. You need a 12V supply for the stepper motor driver, not a 5V one. The Pro Mini version of the Arduino isn't the best choice for you because it doesn't include the USB port...

Thank you very much dc42. Is this a good place to purchase the products from or would you recommend a different source?

I entirely agree with dc42 that the Arduino Pro Mini is not the best choice, but it actually does have the 5V regulator onboard. So that it's possible to run it from 12V - it's the pin labeled "RAW"....

If you want to do it without arduino and programming at all, you'd need a "multivibrator chip" like NE555 to endlessly produce step signals. Then add a switch to set the drivers dir pin HIGH or LOW...

I like that idea very much Olaf. I do not have much experience in this field and simple is good. I already ordered an Arduino but since this project is time sensitive I will likely save that for a...

I recommend you stick with the Arduino. It's very easy to learn to program, far more flexible than hardware alone, and you can change the behaviour easily by reprogramming it.

dc42 is right, arduino will bring you home easier, but it's kind of overkill. -Olaf

If you are planning to use A4988 drivers with 1/16 microstepping, I would consider 0.9° steppers for better accuracy. DRV8825 steppers work well with 1.8° steppers, but would benefit from the "decay...

Hi, thanks for the reply! If I choose to stick with 1.8 degree steppers, is a holding torque of 40N.cm enough? I read somewhere that the holding torque only affects the printing speed, whereby more...

Either of those stepper motors should work OK. The 42SHD0217-24B is better, both because it has higher torque (0.5Nm vs 0.4Nm) and a lower rated current that is more suited to common stepper motor...
