    Hello everyone, I have a project that requires three stepper motors (from OYOSTEPPER) and DM542 controllers. I've looked at many websites and GitHub pages, but I'm still a little lost since I'm just starting out.

    My goal is to provide the Teensy with a set of values generated from a graph, allowing the stepper motors to independently perform a precise number of revolutions (outwards or inwards). The three motors must complete a different number of revolutions, but they will stop at their respective positions until the controller receives new parking coordinates. This position information will be generated from external data, processed (possibly with Node-RED), then sent to Teensy 4.1. To start this project, I purchased two expansion boards from Tinde: a GRBLH board and an Arduino-Teensy 4.1 board.

    I chose the GRBLH board because it is similar to my project, both being based on a three axis CNC machine. The main difference is that I don't need to follow any specific procedure...I just position the three motors in a new location for a few minutes or weeks, as needed, then move them to another location and position them again. The speed at which they reach the designated position is not important, but accuracy is essential.

    My question is: where can I find code suitable for this project?

    THANKS !

    May I respectfully suggest that predetermining hardware/software, based on other operational criteria, may not be the best approach for an actual motion simulator.

    There are members who have used steppers, and I would highlight @Lebois as doing incredible work in that space, but concurrently note he also ultimately switched to servos: https://www.xsimulator.net/community/threads/my-2dof-with-stepper-motors.13558/

    What I am trying to convey is that by all means please feel free to explore possibilities, but at the same time note that often the most efficient, cost effective and easiest path is following in the path of other brilliant innovative members who have already created mind-blowing DIY motion rigs.
