Bug with Cura using 0.16 layer height with a floating object causes 0 print time.

Posted · Bug with Cura using 0.16 layer height with a floating object causes 0 print time.

I'm using version 4.7.0 of Cura with a Creality Ender 3 profile, and when I try and slice a model that's not touching the bed plate, with layer height set to 0.16, Cura acts like it sliced a model, but there's no model, and the print time is zero. It only happens when the model is floating and at the 0.16 layer height.

    I used a 25mm cube.  Yes, with the object floating it doesn't slice (it didn't matter what layer height I used).  With a support block under the model, and the support block set to "Print as support", and with the model just touching the support block, it did slice.

    With the 25mm cube rotated in space so that only 1 point was touching the plate it did slice.  With the same configuration, but the model floating above the plate and touching the support cube it also sliced.  Just floating there it would not slice.

    An oddity was that with a 5mm thick support block located at Z = 0, the model cube I was using also needed to be located at Z = 0 even though it was 5mm above the build plate.


    For a minute there I was thinking that the Cura team had successfully debunked Sir Isaac Newton, but they must have had to back off because in Cura 4.8 beta the issue doesn't happen.  A pity really.  I'm sure that proving "gravity is a myth" would have meant Nobel Prizes all around.
