Topic: .3MM to .1MM scale down settings?

I finally started on .2mm from .3 mm settings after playing with the printer for a while.

I went down to .2mm and printed this for better detail then the .3 but I noticed that the infill at every other infill layer set to 2 the infill broke and looked like a mess like the extrusion thickness was too thin and breaking then you see the gaps at the top infill.

When lowering the layer height to .2 from .3 do I have to reduce the flowrate and extrusion settings? I did reduced the flowrate from .86 to .73 and the part looked ok

But when I went to print a .5mm cal cube. with 1 perimeter, no infill the first layer at .25 came out fine but the next layers all print with what looks like infill? the head slows down and trys to within the single wall jog and fill in the 1 wall width? normally at .3 even .25 the cal cube buzzes through each layer for 30 layers and is done in 5 minutes for wall thickness check.

this one would have taken 30 minutes!!! I played with extrusion width to get it down to .3 and set perimeters even to 2 to see if it would print two bands but still goes super slow and trys to fill in the wall.

Are .2 and lower layers a function of the flowrate vs layer height for wall thickness? Is the .5mm wall for example too thick of a single wall to test the extrusion width? I can try putting the flowrate back to .86 I guess and repeat

also are there other things that should be scaled for lower layer heights? temp, Flow, Extrusion width, extract

Re: .3MM to .1MM scale down settings?

Well I on Ian wordpress page I think my prayers were answered of course! But want to confirm

Using Slic3r the flow rate is calculated automatically based on layer height and diameter so i DO NOT need to scale down from my .3mm settings. So I might be running super low then at my current settings.

The extrusion widths I can leave at .42 for .1 or .2mm settings. Override defaults (which I did)

The Infill every X layers for .2mm I set to 2. Does that mean it will then try to run a .4mm thick infill every 2 layers? do I need to adjust my infill extrusion width to .4 or leave it alone?
(Thinking for .1mm at 3x = .3mm height but if I default it all to .42 will that make a difference?

temp and speed I just need to dial in for .3mm settings and scale speed down (for small .1 layers)

this right?

Re: .3MM to .1MM scale down settings?

If you are trying to print infill every two layers at .2mm layer height, the infill would need to be .4 layer height.  As the nozzle on a standard Solidoodle is 0.35 mm, you're going to have a problem.  I would switch the infill back to every one layer and save that tweek for printing at .1 where you can do every three layers and still be less than .35. 

Of course someone smarter and more experienced than me may have better advice but I believe this is correct.

Re: .3MM to .1MM scale down settings?

That is what I thought as well. Thank You Maybe I can get by with .15MM print and 2 layers at .3
