the problem i having right now is.
a dual line system where both levels run at the same speed and have the same number of parts in them.
it then comes to a lift section that need to load from the last line, then they both move up at the same time and speed to a set position. and then when bot lines have emptied the lift then moves back down to the rest position which is also the load position,
these lines need to move in a forward and a backwards way and they are a feed-in and feed-out of the system.
any help with this system would be great i have a plan of doing the system as a line then moving the lines up at the same time in the 3d world.
this is close to what i am looking for but there would be two lift beds one above the other they will then be feed by two lines then feed off to two lines,
in the same way that yours feeds off no.
Thank you for the video this help me understand that it is possible.
but it is not quite what i am looking for
