I believe I understand exactly what was expressed.
My question is, will laminar flow come into play in an area the is .35mm in diameter. If so, am I understanding correctly, that what you are saying is the length of that .35mm diameter orfice should be 2.5-3 times the width, which would put it at a rough number of .35mm in width x 1.05mm in length?
With a transition from 2mm to .35mm being at say 20 degrees? vs 59 degress that most bits have?
If the reservoir is too small (or nonexistent), then you might notice pulses in the extruded material
Thats funny, with series 1 stock setup, I can see the very very minute vibrations/pulses the stepper creates, in the prints, almost like its printing a record in the smallest detail. In fact that can be seen in some of my pics of the vase prints. Although I cant attribute it to a small reservoir, as I just have never investigated that.

I would also recommend reducing the mass as much as possible in the elements that are heated which will reduce the amount of time required to raise or lower the temperature. However, I'm suspecting that a well tuned PID will be much more critical if the mass is considerably reduced.
I think Ive got a pretty decent mass in that area. From what Im thinking, it isnt too big to heat up and keep heated, and it isnt too small of a mass which will fluctuate all that much. Im betting that it will soak and remain soaked at a consistent level, but only time will tell on that.
I was going to attempt to bring some math in that area, but I dont want to create something that is so locked in, it isnt easily reproducible on a larger scale, for a broad range of different types of printers, using the average hobbyist's tools. Im going to rely on the good ole method of just tinkering to find some middle ground. Although a little math wil probably come into play after I test something.... just because.
Obviously I have to research a bit, but I will definitely take the input into consideration when actually building and testing.
