I'm trying to build a kind of drawbridge with a row of sticky pistons that pushes a row of blocks (the bridge) two blocks up. It works like a charm except for one thing:

The lower sticky pistons correctly moves the upper sticky piston up and down as it should via an ABBA switch. However, the cobblestone block the upper sticky pistons moves doesn't move down as I want it to when the lower sticky pistons pulls down the upper one. The cobblestone block only moves one block up/down when moved by the upper sticky piston.

Is that intended behaviour? I hope not, because otherwise I have no idea how to accomplish my goal without having to rely on sand or gravel instead of cobblestone.

It's all in timing, The second piston needs to extract out one last time at the end of the cycle.
If how I'm thinking it works is correct then this might help,

Umm. I think sticky pistons only move a block one block toward/away to/from a direction. That's the only thing i made out of the post. That it only moved one block

With right Timings you can make it move two I got some setups that do just that.

There's even a video out there I've seen of a THREE block move using three sticky pistons lined up.

But the wiring for it is enormous. Not exactly practical.

I use the two-block shift all the time in my creations. My latest one is a horizontal two-block pull for the secret stairway in my living room. I hid the pistons under my couch (made of fours stair blocks in a row and signs for armrests). The other block that needs to be moved has the piston hidden under the loveseat which runs perpendicular to the couch.

The best part is the lock for it is two levers set on the coffee table in between the seats (in front of the big screen television). I tell people they are my joysticks for my xbox. But really they act as an OR gate. Only one of the four possible combinations of the two lever positions will open the stairs. It's pretty sweet.

Thanks for the link to the video. I think I've seen it before a few days ago. My problem is, however, that I don't just want to move a single block up/down two blocks, but a row of at least four of them. And then the wiring becomes a total nightmare IF it is even possible at all.

Yeah that's pretty much never gonna work. To move one block up/down 2 spaces requires access to all four sides of the piston stack. Obviously if the pistons are in a row you can't access all four sides.

I suppose you could try alternating the push/pull direction possibly... Pull the first block down from below, then pull the next block upwards, third block pulls down, fourth block pulls up, etc. Not even sure if there's enough space to do that.

look up CNBminecraft on youtube he has a pretty good double piston extender

Huh i was under the impression that when a piston pulled anything else, another piston or otherwise, it only pulled that block not anything further attached to it ? I really need to go look at these at some point soon I guess

I used the upward double piston extender from this video and it works everytime. May be the same setup as the other video linked in this thread, so sorry if it is.

Keep in mind that a sticky piston can't pull an extended piston or sticky piston. I didn't know that until I did a little research, so maybe that info will someone here as well.
