The preview does not show the layers at all. Nothing at all, no lines, retracts etc.. I have tried the "native graphics" mode in settings also.
There is also no x,y,z pointers in the main window where i place objects. i can get them to show if i invert y in settings, but then it is useless to me. (this is when using delta setting, round table).
This is not critical to me as it only is a test machine i am running on.
But preview is.
ADDED:
Also the extruder won't retract filament at all.. very weird.. manually i can run it forward and backwards..
