    Problem with NEMA 23 Stepper run by a DM542T driver

    I believe that the problem is now fixed! Originally, I had wired the system based on the driver documentation for a controller with open-collector signals rather than PNP signals. I had also tried reducing the frequency of the pulses to around 200 Hz after itsmoked's comment, which I thought was...

    Problem with NEMA 23 Stepper run by a DM542T driver

    Thank you so much for your input! There's so much about this process that I don't know and still need to learn. I am extremely new to this. So am I using the Pi as a sink or an output? and is there a way to differentiate between these 2 states in code? I had previously thought the GPIO pins...

    Problem with NEMA 23 Stepper run by a DM542T driver

    Thank you for your feedback! I'll look into it. Also, is Logic Signal Current referencing the signal from the RP to the driver? I wasn't too sure what that term meant. Thanks, Will Betts

    Problem with NEMA 23 Stepper run by a DM542T driver

    I am attempting to run a NEMA 23 stepper motor with a DM542T driver from a Raspberry Pi 3b+ using Python. I am supplying the driver with power from a 24VDC 10A Power Supply. The positive PUL and DIR terminals are being powered through a 5V buck converter(with a MAX output of 3A) from the same...
