I use that driver modified to suit my home modified ZWO manual filter wheel, I use a small 4 wire stepper & a DRV 8825 stepper driver board with a Hall Effect Switch that I had originally developed for an ASCOM setup. I just reprogrammed the Arduino to use the sketch modified to suit my home tweaked filter wheel based on the XAGYL protocol works faultlessly, with the indi XAGYL driver, just make sure the capacitor modification to the reset pin on the Arduino is fitted and you’ll have no issues.
