    Hello I currently have a 2dof motion, and I'm starting to develop a linear actuator with stepper motor.

    Already bought some parts:
    3 nema34 9nm @ 4.5A
    3 spindle with pitch 10mm and chestnut
    3 drive tb 6600 50v 5A
    3 48v 7.5A power supply
    1 mega arduino

    The idea would be 2 actuator in the front doing the 6 moves and 1 actuator in the back part in the shaft doing only the movements of heave, pitch and sway.

    I am already manufacturing the mechanical part of the actuators as shown in the attached photo.

    I would like a help from how would that code in arduino for that my idea so that the actuators works with pulse and direction.

    Check @Bordiin work with steppers and arduino, he already have a Nema actuators based sim, and he is also from Brasil.

    Thanks Mariano, I tried to talk to him, and due to a contract with a company can not inform me the code, so in case someone here has more information on how to proceed with a step motor code, I'm thinking of using 1 arduino for each Step motor, so that there is no risk of delay in processing, because stepper motor needs many steps per second.

    In that case have a look at @eaorobbie 's comments on Ard/Steppers here: https://www.xsimulator.net/community/threads/arduino-code-for-steppers.5434/

    And @Harry King's code: https://www.xsimulator.net/community/threads/audrino-sketch-to-run-steppers.9458/

    Hello I returned to the project and follow video of the first tests, then running 30mm up and 30mm down, approximately 125mm / s Now I need to make the communication with the simtools, someone could help me in which the command for the arduino q will read the serial port, and how it receives these values. Of the simtools, as the startup, interface and shutdown. Knowing how I have to receive these signals in arduino, I believe that I can finish the code
