Cura and first layer

[drindt 0]

Hello Forum,

i am using cura 2.1.2 and have an issue by printing this camera mount http://www.thingiverse.com/thing:1704892. The base plate with the hole in the mid must be 1.6mm in height. But after printing it is 1.7mm. It seems that cura adds the thickness of the first layer plus wall thickness top and bottom.

What i should do to achieve the real size from the stl file in the printer?

Thank you a lot for reading.

Daniel

I'm thinking you're printing at .2mm Layer Height and .3mm Initial Layer Height.

This tends to offset the layers by .1mm accounting for the runover from 1.6mm to 1.7mm.

Two things to try:

1. Print at .1mm layer height (better quality prints, but twice the print time)

2. Set .2mm Initial Layer Height. You may have issues getting the prints to stick to the bed pending on your printer, filamant, bed adhesion type...

The model has many non-manifold edges. I run it through https://makeprintable.com/ and was able to repair it. This should work, Here is a fixed file: https://drive.google.com/file/d/0B-702hnJJYE_ZEhLX05uM1VENGM/view?usp=sharing

Let me know if this solves your problem.
