![]() Here are some of the things I found useful: Hey sweet! I have four 5-phase steppers myself! Each one of mine is implemented in a 5-point star pattern. From the doc, it looks like all I should need to move the motor is the pulse signal assuming I am generating it correctly. I assume that a low state should be the default not connected to anything but I have tried grounding the other pins while moving around the pulse pin. ![]() ![]() This all said I am not how to configure the other pins relative to whatever the pulse pin is. The only other measurable change is that with the 5v connected, pins 2 3 and 5 show 1v with ground. If you have any code suggestions let me know. The minimum voltage for the pulse is ~4.5v, looks like I am cutting it close and maybe I am not meeting the minimum fall speed. Image of my oscilloscope reading is below, not sure how accurate it is though. I checked my pulse with my old oscilloscope after tweaking the code a bit. Moving my pulse pin around to (2 3 4 5 6) pins had no effect. Not much luck after connecting pin 1 to the 5v Arduino supply and the ground.
