I’m working on a project that’s making use of an Actuonix Linear Actuators, controlled by TIC825s which are connected to the actuator. The intent is to use a Raspberry Pi 4 and I2C to connect to two stepper controllers and actuate them with Python. Right now I’m trying to run the stepper with the I2C code provided on Pololu’s website (https://www.pololu.com/docs/0J71/12.9), but when I run that code, it simply makes the motor screech and it doesn’t actuate at all. I’ve verified that I’m sending/receiving signal over I2C, and can’t figure out what the issue could be. Does anyone have any experience with something like this?
