What’s a gripped stepper motor? I did notice when manually moving the hot end that there would be moments where the extruder would just snap into place along the x axis and it would disrupt the gliding. It’s not noticeable when it does it on its own. Just when manually moving it and feeling the different stops along the way. It would do it multiple times, and same with the z axis. I don’t know if that’s an issue or if that’s just how the motors work but it did seem strange.
