I am building a mechanical installation that is driven by NEMA 17 stepper motor and DM542 driver.
I could just about work out how to connect these + a controller bypassing the need for Arduino.
However, the motor is heating up, it’s sometimes making very a strange sound and the movement is not always smooth.
I am pleased it’s doing something though, as I’ve NEVER done this kind of stuff before.
I would love to bribe someone who knows this stuff with a canopy from next door and have a five-minute chat
