Thank you for clear step-by-step explanation.
I did a model and make it slice for "thin wall": looking descent with about Flow Tweak = 2. With orifice about 0.3mm walls measured 0.31 - which I think excellent.
After I did slice for "Solid": looking descent with about Flow Tweak = 1.12, but interestingly enough walls start to saffering - they become almost connected dots, where a stepper extruding material and connection where no steps. So, bottom looking solid, almost no open triangles but walls is absolutely unacceptable.
So, I got two parameters, which is contradicting. This is simple calculation algorithm errors.
Reason, why I start to look for solution for working with KS is ununiforrmal printing some parts of the model.
I find your recommendations very useful. But when I do print in Slic3R, all prints and flow rate is calculated with one single user parameter entry. Here in KS it is impossible to reach a balance. I truly believe it need to be corrected inside the software - where is calculation for thin wall and solid fill need to be calculated properly and not need to be adjusted for each wall of the model. In another word, a vehicle driving to North and to South brake shall work identically, based on construction, not a direction of driving. : )
Like we all, most my models what I work has both - Thin Wall and Solid Fill - how it could be fixed on fly ?
So, what the options is left for this version?
What the way to submit this problems to developers, to level they will hear and implement.
