Newbie Confused about Layer Height

[rrowan 0]

Hi Folks,

Earlier this week I received my first 3d printer Ultimaker 2+ (Having an awesome time with the printer)

I know the range for Layer is:

0.25 mm nozzle: 150 to 60 micron

0.40 mm nozzle: 200 to 20 micron

0.60 mm nozzle: 400 to 20 micron

0.80 mm nozzle: 600 to 20 micron

Is there any reason to go from 100 micron to 101 micron? Where would one see a difference in the print? Skip by 10 microns, or more? I do know that 100 micron = 0.1 mm

What is the "normal" range you use? ie: 60, 100, 200, 300?

Also why does the smallest nozzle starts at 60 while the other nozzles start at 20?

Many thanks and my apologies if I am asking something that has been explained 100 times already or this is the wrong forum. If so please someone move it.

I usually print 0.1 or 0.2 layer height. Rarely anything else. Everyone is different. I don't know the other answers.

About the small nozzle: I think the problem is the feedrate. With the tiny hole and very small layers, the feedrate would be so low that the feeder would move by a step only once in a while. apart from that i never tried anything less than 60um and in most cased overall print quality will get worse, e.g. overhangs can get quite ugly at small layer heights.
