I wander, When I change layer thickness in my slice program, What does the printer do? My nozzle does not change, so the width of the plastic can not change. It must be the amount of plastic on top of each layer ... Correct? Is there a max or optimum layer hight in relation to nozzle ? Mine is 0.35 mm.

Yes.
Basically the platform or head depending on the printer moves the layer height for each layer the rate that plastic is fed in depends on that, the speed you're printing and the requested extrusion width.]]> Polygonhell Printing Tue, 08 Jan 2013 12:21:31 -0500 https://reprap.org/forum/read.php?262,174838,175497#msg-175497 https://reprap.org/forum/read.php?262,174838,175497#msg-175497
Remains this question: is the layer hight also the platform advance per layer ? Or will platform advance lass due to plastic layers getting forced a bit into each other ?

Just for info..

So I understand that I could consider 0.35 layers on my 0.35 nozzle?

One more question on the matter: will the Z-direction also move relevant per layer? So 0.2 for the platform at 0.2 layer and 0.3 for the platform at 0.3 layer ?

If you extrude too little plastic then it will snap while extruding, this basically limits the minimum height.
If the w/h ratio is much less than 1.5 then layers don't stick together well, this dictates pretty much the maximum height you can extrude at.]]> Polygonhell Printing Fri, 04 Jan 2013 12:21:50 -0500 https://reprap.org/forum/read.php?262,174838,174838#msg-174838 https://reprap.org/forum/read.php?262,174838,174838#msg-174838
When I change layer thickness in my slice program,
What does the printer do?

My nozzle does not change, so the width of the plastic can not change. It must be the amount of plastic on top of each layer ... Correct?
Is there a max or optimum layer hight in relation to nozzle ? Mine is 0.35 mm.

Advice is appreciated
