I'll try to use the lowest possible belt everywhere in my blueprints. You can load it up in creative mode and replace all belts to a higher level if you'd like to, but the production won't be faster.

Is it possible to make a drawing using mk3-4 tapes?

Ok totally user error on my part. I just linked the belt to the frame, once I pushed the belt back into the merger it works just fine. Sorry for the confusion

But beside the sink issue the factory works great! Just needs managing

I hooked up a sink to the outgoing belt on the right of the factory but nothing came out had to keep containers low to keep others filling

I'll plan to redesign this BP a little bit, but I don't know when: rotate the containers like my other BP-s, do some better belt work, make the Sink internal. In my save it works fine, but the Sink must be used. Have you set it up?

Cool factory unfortunately the overflow doesn’t work so if one thing gets full all production stops. I’m hoping the owner can fix this cause I really like the factory.
