Works for me - a minor optimization that seems like it slipped through the cracks is that one of the multiplexers in the top row isn't actually being used for anything - it's the one to the left of the one just before the routers.

it still works for me. i've uploaded the gif in the walkthrough. hope this helps.

This setup worked perfectly for me. Are you sure you guys put the ABC painters in the correct order?

to fix this all you have to do is bring up hte dispenser of cups and lids with 1 space and bring up 3 new conveyer belts with it, new timer settigns are needed so change B7,8 to B8,9 (same with the other 3 NOT THE TOP ONCE!) and it should work

I'm not getting results with this setup. doesn't paint red stripe w/first order.
