Hello. I am doing my thesis in [factory.io](http://factory.io) about an automate warehouse. I use the stacker crane in Analog mode and I was wondering if I can make the stacker crane start slow and stop slow because the pallets are moved and they do not sit properly in the storage position. Maybe I can do it with a controller but I haven’t thought of anything Can anyone help me ? Thanks in advance ---

The stacker already has an acceleration and deceleration function built in … does that not work for you? I have not used the stacker that much. ---

It use it but still the pallet is moveing a lote and don’t stay in the final position , and on the last positions , the pallets drop from the rack. I see it accelerate and decelerate but on the last position the movement of the pallet is uncontrollably
