Posted on July 05, 2018 at 00:09I am using an X-NUCLEO-IHM03A1 board (powerstep01) to control a stepper motor (17HS24-0644S) speed.When I use the command 'Run (DIR, SPD)' over SPI interface, I observed that the speed in step/s is not exactly the sam...

I think theoretically you can use up to 255 powerstep01 in daisy chain. You cannot stack more than 3 ihm03a1boards because of the way the MISO and MOSI signal are wired inside the board. CPU MOSI -> PS1 MOSI -> PS1MISO->PS2 MOSI-> PS2 MISO -> PS3 ...
