My layer preview has vanished!
Using HOST 1.06.6 on slate 7 series Samsung I find that the layers don't show in the layer preview the bizarre thing is that the first three times i used the program the layer display worked flawlessly how did i break the display??
Still not sure what went wrong but an uninstall/ re-install cycle appears to have fixed this issue.now I just need to work on print quality (layer sepaeration, non-square corners on squares, etc.)
Did you hit the disable filament button in status bar?
