The whole job · 8:36A 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.
