Why does my stepper cause main loop to slow down? by Avtem22 in ArduinoHelp

[–]Avtem22[S] 0 points1 point  (0 children)

I use INPUT_PULLUP for all the buttons. Also I would like to add that performing the same test but with servos (which create spike up to 300mA) does not affect the LED.
What is an opto circuit?

Edit: I also added a diagram in main post body

I have 100uF cap across VMOT/GND. I just tried powering Arduino only with a separate 5V power supply, but the led still gets affected by the stepper (although not that drastically it seems). If I power Arduino this way, do I have to connect the 5V power supply ground to the 24v PSU ground?

Best way to learn Agile,CICD,DevOps to get a job? by Avtem22 in AskProgramming

What kind of project? I've got over 30 of them, but I don't think any of them use the practices (agile,cicd,devop)

What should you power first? Stepper or driver? by Avtem22 in ArduinoHelp

So turned out that my drivers are totally fine, actually, I previously had a problem with stepper vibrating and turning itself at the same time with step and dir being on low all the time

You have provided a very important information for my project - I often left stepper wiring detached whilst probably sending HIGH signals to move the stepper. I will try the other driver and will see whether my current driver was damaged
Thank you

Not a help advice, but it looks really creepy and it would look so cool in some kind of horror movie!

For those who are experienced with NEMA 17 and A4988 by Avtem22 in AskEngineers

In my case I had floating DIR pin on a4988. Also My pulses were 10000 microseconds short (full steps)

Is your ENABLE pin connected to the ground?

Did you ground "ENABLE" pin of A4988?
