John,
?
I use a parallel port mode for the stepper driver. ?The Raspberry Pi has a 40 pin header that can be configured to drive any such device.
?
I currently use a Byte2Bot level shifter to drive a 25 pin cable that connects directly to all my steppers.
?
I originally used a PC, then a Raspberry Pi 4 and currently a Raspberry Pi 5. ?It is a very compact setup.
?
