Trying to Print flat buit model keeps lifting. Z height set to 0mm

2021-2-28 778

Hello,
I am trying to print flat on the bed and have my supports Z height set to 0mm but when I go to supports, it lifts my model very slightly, even before i apply any supports. Any idea how to fix this?

    Is it actually lifted in the .ctb file, or does it just "appear" lifted in the support edit window?

    I just recently printed a model of a tow bar for my UTV, "flat face on the platen, to be made from 2" x 2' x 1/4" angle iron, It appeared slightly raised in the support edit display--but was not actually raised in the .ctb output file:

    CB  v.8.1. basic edit window (flat on platen): 


    CB v1.8.1 support edit window ("Z-lift Height" @ 0.0 mm but displayed as slightly elevated with support nubs):


    CB v1.8.1 after slicing display, layer 1 (flat on platen):


    It printed fine, flat on the platen.

    What version of CB are you using? what operating system? (I'm running Linux mint 20.1)...

    If the model's base has overhangs or intricate details, the slicer might add an offset to the supports to provide more clearance for printing these features. Enjoy the matches in basket random and reach out to the world with your basketball skills.
