Support not printing

[maranello55 0]

Updated to CURA 4.0 and new firmware for my Ultimaker 3 Extended. This is the second case of support not printing after the updates. Hope to get some help from you guys. Thanks!

on blocked nozzle on Extruder 2, I tried printing the Ultibot before starting on this one and it came out perfectly.

Tried with a test model. Still it is not printing the support after the solid layers. However, the support brim is printed well so it is not blocked nozzle. Help
