Only not extended pistons can be pulled back, that I understand. So the top one needs to retract earlier, than when the bottom retracts it will bring the top one. That works, BUT:
Even if I manage the timing so that the top piston is pulled back correctly by the bottom one, when its pulled back only the piston comes back, not the block on top of it.
I have 3 repeaters at the bottom one, so the delay is enormous..: Than when I retract: When the bottom retracts, the top one have been retracted much earlier..so I guess its impossible? Im not much experienced with minecraft.
Is that intended behavior? Is there any workaround?
