50mm X 2MM object printing out as 50mm x 1.5mm

[phillyjon 0]

Hi All,

 

I just got my Ender 3 Pro about two weeks ago.  I have gotten great prints out of it for the most part.  Benchy and a mini-3D printer test came out well.

 

I'm currently having an issue with a very basic test object I created in FreeCad.  It is a simple flat cylinder that is 50mm wide by 2mm tall.  No matter what settings I change in Cura for the slicing, the object prints out 1.5mm high.

 

I'm using a .4mm nozzle

2mm layer height

0.4mm wall line width (all lines are set to 0.4mm)

3 wall lines = 1.2mm walls

0.8mm bottom / top shell

4 bottom layers / 4 top layers

 

Cura shows the slicing as 10 layers. At 0.2mm this should add up to 2mm total height.

 

I've tried:

 - Print thin walls

 - Infill density at 10% and 20%

 - Union overlapping features

 - stl export of item in FreeCad

 - creating a mesh version of the object and then exporting that out of FreeCad

 

Any ideas?

 

Thank you!
