In a comment thread in a previous blog entry, a reader had some questions about how to handle the transfer from 1st to 2nd stage transfer. The basic focus of the discussion both in the comments as well as private were about a general approach to establishing the transfer, yet they have many different types and brands of machines.
Unfortunately, here is no standard for machine response from fill to pack. I have seen some machines stop the screw immediately when 2nd stage is turned off, yet allow extensive overshoot once it is turned on. Other machines have different settings for how over or under-damped you want the machine to behave. You should determine the behavior of your actual machines and then make a procedure specific for those machines so everyone can setup a process the same way.
