Magic Number - Layer Height Calculation

[ShinerG 6]

Hi, 

What's the pitch of the lead screw in the UM3 - is it 8mm?

 

Here's a great video from Filament Friday on the application of the Magic Number for determining the layer height in the Slicer settings. He has loads of other great tutorials too.

The full step magic number for the UM2/Um3/S3/S5 I believe is 0.04mm.  There is 8 substeps so you can go finer accuracy than this but 0.04 is a good number to use for the "magic number".

If I want to print on an S5 with AA 0.8 and BB 0.4 what would be a good layer height for that?

Cura will offer you a 0.2mm profile for this combination so that might indeed be the best choice.
