Z Height Mathematical Computation
Is there a formula to figure what the theoretical perfect height of the Z axis should be based on the nozzle diameter?
What I think would be a better way of setting the height would be to figure what it should be, then only need to make small
live Z adjustments to tweak it. I am thinking a multiplier of say 0.8 might be close, but that does not take into consideration the flow rate of the material.
I am a retired Tool Maker so doing things by numbers is in my blood. 🙂

Sorry not beeing able to give you the correct answer.
A very interesting question. A nice research topic. Which factors have to be considered, for being able to compute z height in regard of nozzle diameter:
Possible examples:
- filament material?
- surface you are printing on (surface tension)?
- nozzle temperature (extruder temperature)?
Which of these factors are really necessary to get an accurate computed z height ...
Lots of questions - but as you said: you are retired so you should have lot of time 😉

My goal is to come up with a number that could be set using feeler gages then just tweak a few thousandth to dial it in.
The Live Z adjustment is nice, but very hard to see what is happening until the entire calibration cycle is finished. A calculated number
would also be a validation for the "eyeball" method.
RE: Z Height Mathematical Computation
Nozzle height depends on many things:
- Nozzle shape,
- First layer width,
- Bed type (smooth, textured, etc)
- Filament type
- Nozzle temperature
You can't quantify the perfect height in number that will fit all of those.
You have to do it by eye. There is no other way.
Also Z calibration takes about 1-3 minutes for first time. And then you can correct it during print in few seconds.
You are trying to overcomplicate it.
