    i am pretty new to this so this question may be stupid to some of you, but i want to control my PoStep60-256 Stepper driver via rs485 with my controllino. Somehow i cant get it to work. Maybe someone can help with it.

    Hello Markus,

    could you please be more specific about what exactly is not working? Please check the proper connection of A and B signals. Also please check the RS485 termination resistor – this shall be done externally. Also check the communication speed and all commands.

    Sometimes it is good to use some USB-RS485 converter and try it via PC so you are sure that you fully understand the communication and the PoStep is working and then connect the Controllino.
