How does that work in the first photo? I'm thinking that the nuts will also turn since the acme thread turned and it would want to pull the nuts toward the direction that the stepper motor is turning. Like the gantry is moved when the X axis stepper turns. Or am I missing something?? I apologize for being so thick headed
