Sending different speeds to different motors through Stepper Motor Stream

Hi Guys,

We're sending 4 different steps information to 4 motors connected to one arduino board every 5 seconds (with a timer) but we also need to send 4 different speeds to match these steps for each motor.

Is that something we can do or is the Stepper Motor Stream component limited to one speed for all four motors at once?

I hope you can help. Many thanks.

Arthur

Hi Arthur, any progress with this? I'm in the exact same situation. Were you able to enter various speeds with Firefly, or did you go with a more custom solution?

Update: Set the speed and acceleration as single numbers (as their are only one input for each).

Then you can vary the speeds of the different motors by altering the # of microsteps inputted, and changing the rate of input using a timer and some graph mapper/custom equations.

An example I came across that helped: https://www.youtube.com/watch?v=HAcyi2ZItkg (by a Nathan Melenbrink)
