for anyone that is having problems with a buzzing or freaking out motor, try to connect reset and sleep pins to 5v instead of each other, that worked for me.

I cannot thank you enough for this. Every time I setup a new stepper, I use your video again! My last comment is 1 year old, in the meantime I started my own channel : )

It's now 2020 and still this comes in handy for someone never built a 3D printer on his own - which is now my current task ( Removing all the crap electronics from an Anycubic Predator ). Thanks a lot, appreciate the info!

Thank you! I tried following other tutorials that included strange libraries but this worked flawlessly. You're the best!

I believe you should use pololus current limit formula which is
current limit = VREF/ 8 * RCS
in this case:
current limit = 0.6/ 8 * 0.1
for the fullstep mode
current limit = 0.6/ 8 * 0.1 * 70/100 = 0.525 A

im still new to this, but it seems more accurate in this and in my case.
this video still helped, thanks!

This is the best explanation for the A4988 on YouTube. Thanks.

[Michael_Harrigan]

Your direct and complete explanation along with great video quality is the best I’ve seen on Arduino so far. Thanks for posting.

[FanucMi]

Great tutorial ! Straight to the point without a lot of distracting information. Thank you. I'm looking forward to setting up my system.

[rusticagenerica]

As usual, your tutorials are unbelievable. Your rock.

[CrL]

Simply amazing. I followed you video and now I have my motor working exactly as I needed it. I just had to modify your code just a bit. Thank you very much.

[Banana-qwhd]

Is there a way I could get the motor to cycle a number of times at certain time of day every day?

I followed this tutorial with all required hardware. I had issues with buzzing and losing consistent position. I used a NEMA17 stepper from an old 3D printer. I solved my issue by connecting sleep/reset pins, adjusting steps to 400 and 800 (0.09deg IPO 1.8deg), and slowly adjusted timing within loops (ended with 660ms). Hope this helps!

Look, I come from Uruguay, I've been searching for a video (in spanish) to understand those fucking drivers and I couldn't find any video to get its function... When I searched for it in english I found this video, I could understand it very quickly. Thank you very much! I wouldn't be able to keep my project without you

A really helpful and informative video. I was struggling with running my stepper motor and I found this. You saved my lot of time.

[instasquid]

This video is still helpful, even after 5 years. Thanks!

[damianbutterworth]

I`m back again using your advice. This time for a telescope EQ drive. Thanks again.

[sasatarle]

great video! i like a detailed explanation of each step, its perfect for a beginner like me. hopefully, in the next one hour my motor will start rotating!

[gowrishankar]

The way of your Explanation was too good.i can understand entire thing, thanku dejan.
its very useful to me..

I had identical parts and it took days of research to figure out why mine wasn't working.
My motor would beep and whine and struggle to move, but in the end I solved this by adding one wire.
All I had to do was apply 5V to the linked RESET and SLEEP pins.
This can be done by running one wire from the same breadboard row as the A4988 VDD pin and running it to the RESET row.
Hope this helps someone!
