I have bought a RS-485 shield for Raspberry Pi a couple of days ago, in order to drive two stepper motors that only use serial communication (sharp look toward Trinamic). I managed to command one motor, however, if I add the second one in parallel, both move simultaneously, having obviously the same target ID.
Could you tell me if this is linked to the way I drive them (I use a C-program of my own, however, the demo-code on Learn-LinkSprite works as well) or if I should ask Trinamic about this?
Thanks in advance,
Have a nice day,
