got some problems with the pneumatic pistons, all connected but the pistons won't move. only things happens is smoke from the exhaust when using the piston.
and how do the chain or belt gearbox parts work??
For the pneumatic components you need to click on the component and set a start and end range. You also need to set the controls in the receiver so they work when triggered.
For the belt or chain components, first place the pulley or gear on a motor shaft. The click and drag on the pulley or gear you just placed to position the output gear and shaft.
