I was planning on using the pico to control a nema 23 motor with a similar driver which makes this video very helpful. You earned a subscription from Algeria, thank you for your efforts.
Very interesting about the print statements and the thumping. Good catch! Great video! Now I can get started on motorizing our vertical blinds which are a pain to open and close because of the location of the stick that hangs down.
Glad it was helpful! The upside of stepper motors is very precise rotational control, the downside is you have to feed them a very consistent pulse stream or the spaz out. Good luck with your blinds project! Cheers Chris
Hi michaelbyron9688 Thanks for the kind words and subscription! I hope to get around to that. Motion control is an area I like to play in a lot. I don't know when I can but almost certainly I will be doing more with these types of drives and motors. Coordinated motion control is not a trivial matter, especially when combining with acceleration and deceleration - so it is a great and fun challenge. Cheers! Chris

Unfortunately not, PWM is not suitable for creating a variable pulse stream. It is however, good for creating a fixed frequency of pulses with a variable amount of duration for the pulse. Cheers! Chris
Thank you Chris! That was very helpful. did you experiment with uasyncio yet to drive three stepper motors independently? that's what I need to do. Not shure if that is precise enough 😑
Hi again, Yeah, unfortunately, old habits are hard to kill sometime. Been referring to motor controls as drivers for about 40 years now, just can't break the damn habit. However, I think my WI accent has mostly faded away;-) Chris

Excellent video! Just subscribed.
A follow-on might be to use the 2nd core, and control 2 motors like might be needed to make a circular path.

Great video, will you be looking at acceleration and deceleration of the motor in the future also maybe controlling the speed with a potentiometer?

Thanks for your video, but I also want to know if can use the PICO PWM to create pulses and control the speed by control the PWM frequency?
Unfortunately not, PWM is not suitable for creating a variable pulse stream. It is however, good for creating a fixed frequency of pulses with a variable amount of duration for the pulse.

very well represented. thanks for. your efforts.
I am glad you liked the video!

Hi CineMuck84,
Usually when I hear "3 stepper motors" I suspect CNC is the goal. Is that what you are trying to do?
Cheers
Chris
❤❤ thank you
OmidAtaollahi ,
Glad you liked it!

You are being confusing. The electronics box is a driver, not a drive. The motor provides the drive.
