Need help operating the NEMA 23 for the C-Beam assembly.

    Hello,

    I am trying to run 4 Nema 23's, each individually so I can raise something up and down on the C-Beam assembly, using a button or switch. I'd like to use an Arduino. Does anyone have any experience with this? Any hardware recommendations? I have tried using a 24V power supply and motor driver, but I am having issues.

    Thanks!

    Is this a CNC machine using grbl to make precise moves, or do you just want to move it manually?

    It is not a CNC machine. I just want to move it manually. I want to raise and lower a small device.

    You may need multiple stackable stepper motor shields. I think an arduino board can only handle 3 with drivers. But i could be wrong.

    Maybe not an Arduino but a Teensy 4.1. It can run the grblHAL which can control 4 individual motors.

    grblHAL not ideal for a non-CNC use case:


    ____

    Arduino, couple switches and a library like GitHub - laurb9/StepperDriver: Arduino library for A4988, DRV8825, DRV8834, DRV8880 and generic two-pin (DIR/STEP) stepper motor drivers (not used it myself, first result in a search for Arduino libraries that support step/dir drivers) with a little custom code will be better

    Which drivers do you have?

    Perfect, will work fine with the solution I suggested. You will have a little bit of a learning curve with Arduino if you aren't already familiar but libraries makes that a little easier

    Could I operate the 4 steppers with this: BlackBox Motion Control System ? and just forgo the tooling part. It seems like the openbuilds software would allow me to operate each stepper individually if needed.
