Great video. I'm using your code in one of my projects. Was wondering how one can implement acceleration and deceleration for soft start and stop the motion.
Thanks. The only option I know of for these types of controllers is to vary the pause time between steps. For example, you could start a series of steps at 200% of the target pause between steps, and then decrease the pause between steps until you reach the target. At then end of the step series, you could start increasing the step pause time. This will work pretty well when you have a long series of steps, not so well when you have a short series. Also, this will work better for belt drives moving heavy loads. Direct drives and light loads don't benefit as much or at all as there is no buffer to absorb and release the step energy.
Very thorough tutorial! I will have to try this some time. Thanks for sharing
Thanks for watching. It would be cool to make an organ of some sort with steppers. Similar to some of the stuff you do.
Thank you. I learned a lot.
Hi, great tutorial. Many thanks
Great tutorial! You helped me a lot, thank you :)
Thanks for telling me.

Need code for a closed loop stepper motor, will this code work to give me positional control?
No. You would have to add code to read the position controller.
Hi, I was wondering where I could download the st.mpy file. It doesn't seem to be in your file depository.
Look in the Funboard V2 repository. It's system_tools.py. Probably in lib builtins.
