A carriage that shuttles between two limit switches, part 1 of 6: The carriage and its rack

The machine drawn from a blank drawing: a bed, end stops and a hanger as rectangles, a 12-tooth pinion with the Gear tool, a rack added under it already in mesh by one right-click, a carriage body and a small flag, and all three made one assembly named Carriage.

A carriage that shuttles between two limit switches: the whole project

A rack-and-pinion carriage and its control logic, built from a blank drawing in six steps. The drawing side is rectangles, the Gear tool, a rack added to the gear by a right-click, and an assembly. The Motion window gives it a slide and a motor; the Controls section adds two limit switches, a counter, two buttons and a gate, and five rules that read as plain sentences; the control panel runs it. It shows a machine's wiring tried out on the drawing before anything is built: what each switch is for, what each rule does, and the log of what happened.
