I printed 6 individual parts (separate print jobs) that all lay flat once cool and off of the printer. The infill was standard rectilinear infill.
Then-
I updated to SO3.02, tried the fast honeycomb infill and started the print.
This new part bows upward in the middle.
The edges don't show any curl at all. The part was flat but as it cooled the center of the part lifted.
The shape of the part is a little like a 4-legged spider. The legs all touch the table while the body (center) is raised up by 1.7mm.
Anyone having issues with the honeycomb?
I am trying 'full honeycomb' now to see if the curvature goes away.
