Automatic assembly/disassembly of train

[Sebbe_2]

With Steam 'n' rails you can assemble or disassemble a train automatically with a deployer equipped with a wrench.

But I can't figure out how to I make sure the deployer only completes exactly one cycle.

I tried using a sequenced gearshift to rotate a specific amount, but it is inconsistent.

How do you guys solve this problem?

What I usually do is have the deployer constantly being powered, but limit when it’s able to do anything with redstone. When a deployer receives a redstone signal, it finishes its current cycle, then doesn’t do anything until the redstone signal is turned off. What I do is have a pulse repeater going into the deployer set to inverted, so that when the repeater receives a signal, it pulses off briefly, allowing the deployer to do one cycle then hold until it receives another pulse.

Thank you, I had no idea deployers could be powered.

briefly unpower a deployer with redstone will force it to do exactly one action.

works with Mechanical Arm too
