[Screenshot 2022-09-07 160454] I am attempting to use 3 stepper motors to create an accurate x-y stage to move a sensor to 100 different positions above a 7ft^2 area. The motor I am using is the STM24QF-3RE NEMA 24 from Applied Motion Products. This motor has its own "Q-programming" for stand alon…

What is your level of programming skill? How complex are the tasks that the x-y stage must perform? It's impossible to suggest a target controller without understanding the application requirements.

Thank you for reaching out. I have practically no programming skills, but the tasks required seem pretty basic. I have attached a picture of the requirements of the stage, as well as a few pages of commands from the command reference sheet of the motor to give an idea of what it is already capable o…

[image] mnorm123: I have attached a picture of the requirements of the stage I don't see that. Am I misinterpreting the images?

[image] mnorm123: so I'm not sure if an Arduino is needed at all. Something has to tell each motor controller exactly what to do. What is your level of understanding about how that communication takes place? What decides what the motors are supposed to do? That is, go from project plan …

I see now. Is this a project that you undertook for someone else? An Arduino can probably do this. These requirements are very basic, there is no mention of the method of specifying tasks (i.e. how the x-y will be told what to do). Do steppers need to be synchronized to move in unison or is it okay …

While it's possible to do this with an arduino, it will be far simpler with something more powerful. What's more, that company already provides software that lets you download stored motion programs to its controllers. I'd start with that. If you need something more sophisticated and are looking fo…

If your positioning accuracy limit is +/- 1mm over "7ft^2 area" does that mean you need a 7-foot beam that won't sag more than 1mm in the middle? That is a VERY stiff beam. How much weight does this positioner have to carry?

I appreciate the offer but it is a group project and I can outsource the programming to someone else. However, you understand the scope of this project so I'm curious, what Arduino model or other controller would you use in this scenario. It just has to communicate to the motors using the software t…

I wouldn't use an arduino. Faced with the same problem, I used a PC and wrote the code in C# with a pretty cool GUI to control the machine gantry.

here is just the picture of the requirements. If that is not loading I can type it out
