| May 9, 2022 at 20:55 | comment | added | StanberyTrask | ok after waking up and taking a second look at it it appears to be a wiring mistake on my part, instead of being wired to pins 10 and 9 dir and step where on 9 and 8 and i feel a bit silly, but before moving to 10 and 9 the driver was connected to pins 3 and 2 and was still having the same erratic behavior. and the motor simply wont turn if plugged into the adjacent pins ((2 & gnd) / (4 & 3)) and the program adjusted. so i guess problem solved for me at least | |
| May 9, 2022 at 18:36 | comment | added | chrisl | When you measure such voltages on the digital output of the Arduino there is something electrically wrong. Do these voltages persist, when you are not connecting the stepper driver (only the Arduino without anything connected)? Is the 5V pin staying at 5V when you have the stepper driver connected? | |

| May 9, 2022 at 10:11 | comment | added | StanberyTrask | the arduino is plugged in with usb and im using the 5v output on the micro (and i can confirm its 5v), and im also lead to believe that the digital pins operate at 5v | |
