I’m having a problem with printing the lower portion of a 2" diameter spherical shape.
One section, always at about the 10 o’clock position, is flat or concave while the opposite side has the correct convex shape. To make things more peculiar, this only happens on the first (lowest level) shape when printing a stack of such shapes.
I am printing ABS using Cura v17 running on a TAZ 5 with 0.35mm nozzle.
I’ve tried different bed temps, different filament temps and raising the first print off the bed; all to no avail.
I’ve included an STL file that I’ve used to do tests with in case anyone else wants to try to duplicate my result.
Any suggestions greatly appreciated.
