Conveyor won't start upon engine signal having physics enabled

Hey all,

I searched the forums regarding my issue without success.

What I try to achieve is: a robot picks up a part (an euro pallet in my case) and drops in on top of a conveyor. The conveyor’s engine input is then set but the pallet doesn’t start moving.

I tried with batch conveyor as well - same behavior.

What am I doing wrong?

KUKA.SimPro 3.1 (3.1.0)

Thanks in advance!
